AD3987E6FA38FFDB50B6FE54FB64BB4E.taxon	discussion	Remarks. Hutton submitted a description of Unio depauperata to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 d: 216), and was preempted by a brief description of Unis [sic] depauperata in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 h: 478). Hutton (1884 d) noted that this taxon was “ perhaps an impoverished form of U. zelebori [Dunker, 1866: see Marshall & Fenwick 2006], but too distinct to be passed over ”. It has been treated as a subspecies of the morphologically variable species Unio menziesii Gray (e. g., by Simpson 1900: 890; 1914: 1292; Suter 1913: 941; Dell 1953: 231) and as a junior synonym of U. menziesii by McMichael & Hiscock (1958: 460), Powell (1979: 384) and Marshall et al. (2014: 10). The last-mentioned species is endemic to New Zealand, and is widely distributed in lakes, rivers and streams in the North and South Islands, and on Great Barrier Island (Marshall et al. 2014: 12, fig. 6).

AD3987E6FA38FFDA50B6FA25FE67BCCA.taxon	discussion	Remarks. Based on one or more specimens collected by John Enys. Hutton submitted a description of Unio rugatus to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 d: 216), and was pre-empted by a brief description of Unis [sic] rugatus in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 h: 478). Unio rugatus Hutton, 1883 is a junior homonym of Unio rugatus Menke, 1828, and was renamed Diplodon (Hyridella) menziezi [sic] rugulosus by Simpson (1914), based on Hutton’s type material from Lake Pearson. This taxon has been treated as a subspecies of the morphologically variable species Unio menziesii Gray, 1843 (e. g., by Suter 1894 b: 291; 1905: 238; 1913: 943; Simpson 1900: 889; Simpson 1914: 1291) and as a junior synonym of U. menziesii by Dell (1953: 230), McMichael & Hiscock (1958: 460), Powell (1979: 384) and Marshall et al.

AD3987E6FA39FFDD50B6FC14FC15BC20.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 140), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 282). A re-description and illustration of Leptopoma calva by Suter (1913: 179, pl. 35, fig. 1) was based on the type material from Canterbury Museum. Suter (1913: 179) and Dell (1955: 1136) stated that this species was known from the type specimen only. The latter author noted that Suter’s (1913) “ description and figure are not highly diagnostic. Unfortunately the type cannot at present be located in the Canterbury Museum, and no topotypes appear to have been collected ”. Dell (1955: 1136) identified material of “ a moderately common shell in Fiordland ” as Murdochia cf. calvum (Hutton), but noted that “ until these shells can be critically compared with undoubted specimens of calvum, the identification cannot be certain ”. Marshall & Baker (2007) redescribed Leptopoma calva Hutton, 1882 as part of a taxonomic review of Cytora Kobelt & Möllendorff, 1897, noting that the shell of this species is distinctive in having a maculate colour pattern, although the latter feature was not mentioned in the descriptions by Hutton (1882 p, 1883 d) or Suter (1913), and they identified ‘ Murdochia cf. calvum ’ of Dell (1955) as Cytora mayhillae Marshall & Barker, 2007. Marshall & Barker (2007: 60) selected a neotype of calva, NMNZ M. 174790 (pl. 1, fig. C), that “ represents the only Cytora species occurring in the vicinity of Greymouth that is accordant with Hutton’s descriptions and Suter’s (1913) crude illustration of the holotype ”. This in itself is not sufficient justification for the designation of a neotype under ICZN Art. 75.3 but, given that previously there had been confusion over the identity of calva, we agree that a neotype was required to stabilise the nomenclature. The neotype selected by Marshall & Barker (2007: 60) was from the Otira-Kumara Highway, c. 45 km SE of Greymouth; they stated that they had “ not seen any reliably localised specimens from Greymouth or the immediate vicinity of that town, so we have chosen the neotype from one of the nearest localities where the species is definitely known to occur ”. Subsequently, C. calva has been found living in Omotumotu Bush, Greymouth, and on Peter Ridge, and near Point Elizabeth, on the southern and northern outskirts of the town, respectively (F. Brook pers. obs.). Current taxonomy.

AD3987E6FA3EFFDD50B6FD88FC2AB876.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 184), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 477). There are no published illustrations of the original type material. Marshall & Barker (2007: 94) redescribed this species, noting that it is “ highly distinctive in the combination of large size (height up to 6.85 mm), narrowly conical spire, and especially the presence of rather strong, widely spaced spiral threads on the first whorl of the protoconch ”. However, their synonymies indicated that some earlier workers had confused pallida with other congeners, including Cytora kerrana Gardner, 1968, C. maui Marshall & Barker, 2007 and C. tokerau Marshall & Barker, 2007. Marshall & Barker (2007) designated a neotype of pallida, NMNZ M. 174819 (pl. 1, fig. D), on the basis that type material appears to no longer exist. This in itself is not a sufficient reason under ICZN Art. 75.3, but the fact that this species name had been misapplied by some earlier workers means that designation of a neotype to prevent confusion over the identity of this species, and stabilise the nomenclature, was appropriate.

Lectotype designation and identification of paralectotypes by Marshall & Barker (2007: 94). According to a note in the CMNZ accession register (by D. Gregg, 8 May 1968) the type lot M 1266 originally contained four specimens. The molluscan collection at CMNZ has a radula mounted on a glass slide with the label details ‘ Leptopoma pannosa, Greymouth, XVI p. 173 ’, in Hutton’s handwriting (i. e., CMNZ 2017.17.46), which is also probably primary type material (see description of radula by Hutton 1883 d: 140), but whether it is from the lectotype, or a paralectotype, is not known. There is a dab of glue residue on this glass slide, suggesting that some other item, possibly the operculum illustrated by Hutton 1884 b: pl. 10, fig.

AD3987E6FA3CFFDF50B6FF74FED6BA15.taxon	discussion	Remarks. Primary type material of Rissoa vana Hutton is illustrated here for the first time in pl. 1, fig. G. The original description of this species was based on one or more specimens collected from Awamoa Creek, Oamaru. Hutton (1873 c) interpreted vana as a marine species derived from a Miocene fossil assemblage, but Finlay (1924: 491, 493) pointed out that it is a synonym of the extant freshwater snail Amnicola badia Gould, 1848 [= Potamopyrgus antipodarum (Gray, 1843)]. Finlay (1924) noted that this species was common in Awamoa Creek and suggested that the type material of vana was probably collected from Recent flood deposits. Potamopyrgus antipodarum is widely distributed throughout New Zealand in fresh and brackish water (Winterbourn 1970, Haase 2008: 103). It also has a wide adventive distribution in southeastern Australia and Tasmania (Ponder 1988) and Europe (e. g., Welter-Schultes 2012: 40), and is adventive also in North America (e. g., Richards et al. 2001, Alonso & Castro-Diez 2008) and Japan (Shimada & Urabe 2003). Current taxonomy. A subjective junior synonym of Potamopygus antipodarum (Gray, 1843) — Finlay (1924: 491, 493), Marshall (1996: 20).

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1884, but publication was delayed until May 1885 (Hutton 1885 c: 55), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1884 h: 175). Treated as a junior synonym of Succinea tomentosa Pfeiffer, 1855, by Hubendick (1951: 180) and Dell (1956: 76). The latter taxon, which was described from material collected in New Zealand, was transferred to Austropeplea Cotton, 1942 by Smith (1992: 257). As presently interpreted A. tomentosa has a wide but patchy distribution in the North and South Islands, with records from Northland to Otago, in seepages, swamps, small bodies of standing water, and less frequently in lakes and running waters (Dell 1956: 78; Pullan et al. 1972: figs. 1 a, 1 b). It has also been recorded from southeastern Australia (e. g., Hubendick 1951: 170, fig. 361; Boray & McMichael 1961; Smith 1992: 257; Puslednik et al. 2009: fig. 1 a), but molecular studies indicate that the New Zealand populations of A. tomentosa form a distinct endemic lineage that is not conspecific with any of the Australian populations previously attributed to this taxon (Puslednik et al. 2009).

Species name unnecessarily emended to pusilla by Hedley & Suter (1893: 625). Hubendick (1951: 171, 179, 200) treated Limnaea pucilla Hutton, 1884 and Limnaea alfredi Suter, 1890, which was based on shells from Hooker Valley, Canterbury, as synonyms of Limnaea tenella Hutton, 1884, and noted that the shells of this taxon were similar to those of the European species Galba truncatula (Müller, 1774), albeit with a less elevated spire. Dell (1956: 73) observed that pucilla was based on immature shells and had not been recorded subsequently from the type locality. He suggested that this species most closely resembled Limnaea alfredi Suter, 1890, which was listed as a junior synonym of G. truncatula by Climo & Pullan (1972: 6 — in Lymnaea). Dell (1956) noted it was possible that “ the types of pucilla are juveniles of introduced or even foreign shells, which never lived in New Zealand ”, and he recommended that the name pucilla be considered indeterminate. Marshall (1996: 34) indicated that the type material (see pl. 1, fig. K) was well preserved and identification should be possible, and he suggested that pucilla may be based on juveniles of an introduced species.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1884, but publication was delayed until May 1885 (Hutton 1885 c: 55), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1884 h: 175). Hubendick (1951: 171, 179, 200) treated Limnaea pucilla Hutton, 1884 and Limnaea alfredi Suter, 1890, which was based on shells from Hooker Valley, Canterbury, as synonyms of Limnaea tenella Hutton, 1884, and noted that the shells of this taxon were similar to those of the European species Galba truncatula (Müller, 1774), albeit with a less elevated spire. However, according to Dell (1956: 73), L. tenella is based on juvenile shells of Lymnaea stagnalis (Linnaeus, 1758). Hutton (1882 h: 157) had earlier noted that the latter species had been “ introduced intentionally into the river Avon at Christchurch, and is now abundant at the Acclimatization Gardens ”. According to Thomson (1922: 259), L. stagnalis was originally introduced to the Avon “ from England in 1864, by Mr A. M. Johnson of Opawa [Christchurch], who brought them out as food for the fish he was endeavouring to introduce ”. Dell (1956: 73) noted that L. stagnalis was “ widely distributed in sluggish streams and particularly in lakes throughout New Zealand ”. Pullan et al (1972: 397, figs. 1 a, 1 b) indicated that it had a sparse distribution in the North and South islands, in lakes, ponds, man-made dams and slow-flowing streams. Lymnaea stagnalis is native to Eurasia, the western part of North Africa, and central and western North America, and has a wide adventive distribution that includes Australia and New Zealand (Hubendick 1951: 118, fig. 301; Welter-Schultes 2012: 50).

AD3987E6FA20FFC250B6FD51FD22BC20.taxon	discussion	Remarks. The original description was based on a single individual (Hutton 1879: 332). There are no published illustrations of the holotype of Konophora marmorea, which was collected in Dunedin by the Articulator to the University of Otago Museum, Mr. F. J. Bourne (Hutton 1884 c: 206, incorrectly cited as Browne by Hutton, 1879: 332). Hutton (1882 i: 158, pl. 5, figs. 1 – 9) subsequently described and illustrated the external morphology and anatomy of another individual of K. marmorea that he had obtained from Professor T. J. Parker of the University of Otago. This is probably the same specimen that Hutton (1898 – 1900: 10) referred to as a ‘ cotype’ of Athoracophorus (Konophora) marmorea in his List of types in the Canterbury Museum. This specimen, which is here considered to be a topotype, rather than primary type material, was not found during a search of the CMNZ collection in 2017 and is apparently lost. However, the molluscan collection at CMNZ has a radula mounted on a glass slide with the label details ‘ Janella marmorea, Dunedin, XIV p. 159 ’ in Hutton’s handwriting (i. e., CMNZ 2017.17.120), which appears to be the same one that was illustrated by Hutton (1882 i: pl. 5, fig. 8). The molluscan collection at NHMUK contains a preserved specimen from Dunedin, confusingly labelled ‘ Konophora marmorata Hutton’, which was sent from Otago Museum to London as an exhibit in the Colonial and Indian Exhibition of 1886, and subsequently purchased by the British Museum (i. e., NHMUK 1886.11.18.22). This is possibly the specimen that Cockerell (1891 b: 217) listed as ‘ Athoracophorus marmoreus forma nov. ’; he noted that this specimen “ differs very much in colour from Hutton’s description of the type ”, but this is not taxonomically significant, because athoracophorids typically loose pigmentation rapidly in alcohol (G. M. Barker pers. comm. 2020). Barker (2018: 216, 229) treated NHMUK 1886.11.18.22 as the holotype of K. marmorea Hutton, 1879, but this is not consistent with Suter’s (1913: 796) statement that the type was in Otago Museum. Furthermore, neither the NHMUK molluscan accessions register nor the specimen label of NHMUK 1886.11.18.22 list the collector, refer to this as a type specimen, or state that the identification was by F. W. Hutton. Suter (1913: 796) recorded Athoracophorus (Conophora) marmorea from several widely scattered localities throughout New Zealand. Burton (1963: 52, 53), in a review of New Zealand Athoracophoridae, noted that Konophora marmorea “ is almost unrecognizable from Hutton’s description, and until the type specimen is found …. must remain incertae sedis ”. Burton (1963: 53, 54) considered that all of Suter’s (1913: 796) locality records of marmorea except for Dunedin, the type locality, referred to another species. He proposed the new name Athoracophorus suteri Burton, 1963 for A. marmorea sensu Suter, 1913 [non K. marmorea Hutton], listed the ‘ type’ as being in the Otago Museum, Dunedin, but did not provide information as to where or by whom the type material had been collected, and he did not select a type locality. No record of type material of A. suteri was found during a search of the Otago Museum collection in 2017 (Emma Burns and Kane Fleury, pers. comm.). Barker (2018: 237) treated A. suteri Burton as an objective synonym of K. marmorea Hutton, 1879, incorrectly stating that it had the same type locality, and was inadvertently based on the same type material, as the latter species. However, this taxonomic decision does not stand scrutiny. The original description of A. suteri Burton, 1963 explicitly stated that this species is not conspecific with K. marmorea Hutton, 1879 and, contrary to Barker’s assertion, Burton (1963: 54) did not record A. suteri from Dunedin. Burton’s statement that the type material of suteri was in the Otago Museum probably was an error, but that in itself does not constitute inadvertent typification “ by reference to the type of K. marmorea Hutton, 1879 ”, as suggested by Barker (2018: 237).	en	Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D., Spencer, Hamish G.

AD3987E6FA21FFC550B6FD89FDC7BE8B.taxon	discussion	Remarks. The original description of this species was based on material from Wellington and Dunedin that was collected by Hutton himself (Hutton 1884 c: 206). The type series was evidently split between collections at Otago and Canterbury museums (Hutton 1898 – 1900: 10; Suter 1913: 803). The collection at NHMUK contains a specimen from Dunedin labelled ‘ Janella papillata Hutton’, which was sent from Otago Museum to London as an exhibit in the Colonial and Indian Exhibition of 1886, and subsequently purchased by the British Museum (i. e., NHMUK 1886.11.18.18). It is possible that this specimen is part of the type series, though the NHMUK molluscan accessions register and label details do not refer to it as type material, list the collector, or state who identified it. As discussed by Barker (2018: 218, 232), there has been considerable confusion over the identity and distribution of Janella papillata Hutton, 1879. It was listed as a variety of Janella bitentaculata (Quoy & Gaimard) by Hutton (1884 c: 206) and Hedley (1893: 158), and subsequently reinstated as a full species by Cockerell (1891 b: 217), who designated it as the type species of Pseudaneita Cockerell, 1891, based on morphological characters of the specimen in NHMUK 1886.11.18.18. Redescriptions of non-type material identified as Pseudaneita papillata were given by Suter (1913: 801) and Burton (1963: 61), who considered that this species was widely distributed throughout the South Island and the southern North Island. However, Barker (2018: 232) re-examined type material of Janella papillata Hutton, 1879 in OMNZ that had been collected in Wellington, and the specimen from Dunedin (ex OMNZ) in NHMUK 1886.11.18.18, and determined that at least two different species of athoracophorid slugs were represented. He designated a specimen from Wellington as the lectotype of J. papillata Hutton, 1879, noting that it is a “ a common North Island, New Zealand Athoracophorus species, distinct from A. bitentaculatus (Quoy & Gaimard) ”, and restricted the type locality of papillata to Wellington. He noted that the specimen in NHMUK 1886.11.18.18, and material from the South Island and southern North Island that most New Zealand workers from Suter (1909: 325) onwards have identified as papillata, is a different, as yet undescribed species. Barker (2018: 218) also pointed out that this has implications for the status of Pseudaneita Cockerell, 1891, which is unresolved at the time of writing.

AD3987E6FA26FFC550B6FF3CFB60BB16.taxon	discussion	Remarks. Hutton submitted a description of Fruticicola adriana to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 175), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). A shell from the type series (lectotype) is illustrated here for the first time in pl. 2, fig. A. There has been confusion over the identity and distribution of this species. It was recorded from Napier and Banks Peninsula by Hutton (1884 c: 201), from Banks Peninsula and a few North Island localities by Hedley & Suter (1893: 639) and Suter (1894 b: 252), and from mid Canterbury and throughout the North Island by Suter (1913: 637) and Powell (1979: 319). In a systematic review of Allodiscus and related genera, Marshall & Barker (2008: 80, fig. 9 A) reinterpreted Allodiscus adriana as a morphologically variable species with a wide distribution in the South Island extending from the vicinity of Reefton to Bluff. They listed Allodiscus smithi Suter, 1894, from Mt Somers in mid Canterbury, as a junior synonym of Allodiscus adriana (Hutton, 1883), albeit noting that type material of the two taxa differs morphologically. Preliminary results of a phylogenetic study indicate that Allodiscus adriana sensu Marshall & Barker (2008) is in fact a complex of morphologically-similar but genetically distinct species, with typical Allodiscus adriana (Hutton, 1883) presently known from scattered records between Banks Peninsula and North Otago only (M. Kennedy & T. King unpub. data). Genetic data are not yet available for A. smithi, but differences in shell morphology compared to adriana suggest that it should be reinstated as a valid species. The systematic relationships and distributions of other taxa in the ‘ adriana ’ complex from Canterbury, Otago and Southland are the subject of ongoing investigations. Current taxonomy. Allodiscus adriana (Hutton, 1883) — Hedley & Suter (1893: 639), Suter (1913: 637), Powell (1979: 319), Marshall & Barker (2008: 80), Spencer et al.

AD3987E6FA26FFC450B6FA9EFDE6BDD7.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 175), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 475). Hutton (1883 g, 1884 b) recorded P. bianca from Greymouth only, and Hutton (1884 c: 192) listed additional records from ‘ Auckland’ and ‘ Horokiwi, Wellington’ in North Island, and ‘ Bealey’ in South Island. There are no published illustrations of the type material of Patula bianca Hutton, 1883 and, as already noted, the type specimen (s) appears to have been lost. Nevertheless, Hutton’s (1884 b: 175) description is accordant with one particular species living in the vicinity of Greymouth. Examination of the literature and museum collections indicates that this taxon was identified as bianca by Henry Suter, who undoubtedly would have examined the type material that was formerly present in Canterbury Museum, Christchurch, when he was working there (see Hyde 2017). New Zealand malacologists following on from Suter have also consistently used this name for the same taxon. One other species living in the vicinity of Greymouth, Paracharopa rimu Climo, 1985, has very similar shell morphology to, and is locally syntopic with bianca, but differs from Hutton’s (1884 b: 175) description of the latter species in lacking a radial colour pattern. The fact that there does not appear to have been confusion over the identity of P. bianca means that designation of a neotype is not warranted. Suter (1892 e: 293, pl. 21, figs. 21, 22), described and illustrated the jaw and radula of a specimen (s) from ‘ Forty-mile Bush, North Island’. The first illustrations of a shell of P. bianca were by Pilsbry (1892 [in 1892 – 1893]: 97, pl. 37, figs. 41, 42), probably based on material that had been sent to him by Suter (i. e., ANSP 63792, 63793). Descriptions of the shell, radula and reproductive anatomy of bianca were given by Suter (1913: 703, 1915: pl. 27, fig. 18, a) and Climo (1970: 290, table 2, text figs. 8 F, 13 F, 20 C, 22 I, pl. 1, fig. D). A topotype of Patula bianca Hutton, 1883 from near Point Elizabeth, on the northern outskirts of Greymouth, is illustrated here in pl. 2, fig. B (NMNZ M. 329345). Hedley & Suter (1893: 655), Suter (1893: 147, 152) and most subsequent authors have assigned this species to Charopa Albers, 1860 at genus or subgenus level. However, preliminary results of a phylogenetic study indicate that it belongs instead in Paracharopa Climo, 1983 (M. Kennedy unpub. data), as has been suggested previously by Mayhill (1994: 31, 32, 37, 38) and Worthy & Holdaway (1994: 391). This species has a very wide distribution in the New Zealand region (below).

AD3987E6FA27FFC750B6FBDDFAEABA63.taxon	discussion	Remarks. Hutton (1884 b: 182) noted that “ The only specimens I have seen were old and rubbed ”, which suggests that the type material originally may have consisted of more than one specimen. He recorded the locality as Napier but did not state who had collected the type material. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 181), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). There has been confusion over the identity and distribution of this species. It was tentatively assigned to Charopa Albers, 1860 by Hutton (1884 b: 181), transferred to Psyra Hutton, 1883 by Hutton (1884 c: 201), and included in Allodiscus Pilsbry, 1892 by Pilsbry (1892 [in 1892 – 1893]: 66, pl. 22, figs. 37 – 39) and subsequent authors. Hutton (1883 g: 477, 1884 b: 182, 1884 c: 201), Pilsbry (1892 [in 1892 – 1893]: 66), Hedley & Suter (1893: 638), and Suter (1894 b: 251) recorded this species from Napier only. Suter (1913: 638) thought that “ the locality Napier, as stated by Hutton, is wrong ”, and that Hutton’s species was instead from the Three Kings Islands, and this reinterpretation has been followed by subsequent workers, including Powell (1935, 1948, 1951, 1979), Climo (1973), Spencer & Willan (1996: 40), Brook (1999 a, 2002) and Marshall & Barker (2008). Suter (1913: 637 – 638) gave a description of putative cassandra based on specimens collected by Thomas Cheeseman and Captain John Bollons on Great Island, Three Kings Islands, but an accompanying illustration (Suter 1915: pl. 9, figs. 2, 2 a, 2 b) was of the type specimen previously illustrated by Pilsbry (1892 [in 1892 – 1893]: 66, pl. 22, figs. 37 – 39). Climo (1973: 568) suggested that the type material of cassandra had been collected on Three Kings Islands by Cheeseman, but this is incorrect because the latter’s first visit there, and indeed the first known visit to these islands by any naturalist, was in 1887 (Cheeseman 1888, 1891), several years after the original description of this species. Suter (1913) was undoubtedly correct in inferring that the record of Charopa cassandra Hutton, 1883 from Napier was erroneous. There are no extant or fossil land snail species known from Napier or elsewhere in the North Island that correspond to the descriptions and illustrations of this species, indicating that the type material was definitely mislocalised. However, although there are some similarities between Charopa cassandra as described by Hutton (1883 g, 1884 b) and illustrated by Pilsbry (1892 [in 1892 – 1893]) and Suter (1915), and the taxon from Three Kings Islands that was described by Suter (1913) and Marshall & Barker (2008), there are also some important morphological differences. These include the fact that the latter has a closed rather than a narrowly open umbilicus; it has weak, almost obsolete axial ribs on the teleoconch, rather than very fine ribbing; it has a less elevated spire; and it has a different colour pattern, with broad, radiating, reddish-brown streaks at the suture, that transform into more numerous, irregular, anastomosing, wavy or zigzag axial bands on the periphery and base. Re-examination of recently rediscovered type material of Charopa cassandra Hutton, 1883 indicates that it is in fact conspecific with, and a junior synonym of, Phacussa fulminata (Hutton, 1882). The holotype of the latter species is a fresh, modern shell from Rakiura / Stewart Island (see entry for Zonites fulminata below), whereas the lectotype of Charopa cassandra Hutton, 1883 is a larger fossil shell that closely matches Phacussa fulminata from Holocene dune deposits on Native Island in Paterson Inlet, Rakiura. The species of Allodiscus from Three Kings Islands that was referred to as cassandra by Suter (1913) and subsequent authors is un-named and requires formal description. Taxonomy.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 136), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 281). Descriptions by Hutton (1884 b: 171) of a jaw and radula of cornea were probably based on the putative type material in CMNZ 2017.17.2 mentioned above, whereas the description of an animal purported to be cornea was based on a specimen from Greymouth that was neither type material of, nor conspecific with, Amphidoxa cornea Hutton, 1882. From Pilsbry (1893 [in 1893 – 1895]: 18) and Hedley & Suter (1893: 643) onwards, cornea has generally been assigned to Flammulina Martens, 1873 at subgenus or genus level. Examination of material in museum collections indicate that it is a relatively scarce species with a sparse distribution in northern New Zealand (below). Current taxonomy. Flammulina cornea (Hutton, 1882) — Hedley & Suter (1893: 643), Suter (1913: 675), Powell (1979: 313), Spencer et al.

As noted in the section on Hutton’s genus group names (above), Calymna Hutton, 1883 has been incorrectly interpreted as a homonym of Calymma Hübner, (1816 – 1826) 1823 [Lepidoptera] by Pilsbry (1893 [in 1893 – 1895]: 17), Suter (1913: 671), Thiele (1931 [1929 – 1935]: 575), Zilch (1959 [in 1959 – 1960]: 222) and Schileyko (2001: 1025), based on a subsequent misspelling of the latter name as ‘ Calymna Hübner’ by Walker (1858: 13).

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 137), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 281). A shell from the type series (lectotype) is illustrated here for the first time in pl. 2, fig. H. The species name has been consistently listed as helmsi by New Zealand authors from Hutton (1884 b: 172, 1884 c: 205) onwards (e. g., Suter 1913: 624, Powell 1979: 315, Spencer et al. 2009: 215), and because this subsequent spelling has been in prevailing use since 1884 it is deemed to be correct under ICZN Articles 33.4 and 33.3.1. Descriptions by Hutton (1884 b: 172 – 173, pl. 10, fig. I, pl. 11, fig. W) of the jaw and radula of helmsi were probably based on the putative type material in CMNZ 2017.17.117 – 2017.17.119 mentioned above. Zonites helmsi is the type species of Phacussa Hutton, 1883, by subsequent designation of Pilsbry (1893 [in 1893 – 1895]: 12). Phelussa Iredale, 1915 is an unnecessary replacement name for Phacussa Hutton, 1883. Phacussa helmsi has been interpreted as having a wide distribution in the southern South Island (e. g., Suter 1913: 625; Powell 1979: 315), but this refers to a species complex (M.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 179), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). From Pilsbry (1893 [in 1893 – 1895]: 18) and Hedley & Suter (1893: 643) onwards, jacquenetta has generally been assigned to Flammulina Martens, 1873 at subgenus or genus level. However, whereas the protoconch of Flammulina zebra (Le Guillou, 1842), the type species of this genus, is smooth and lacking in sculpture, that of jacquenetta has a distinctive sculpture of diagonally reticulated riblets with beaded intersections, which indicates that these two species are probably not congeneric. Recorded from Greymouth only by Hutton (1884 c: 198), Suter (1913: 679) and Powell (1979: 314), but examination of material in museum collections indicates that jacquenetta has a sparse distribution in the northwestern South Island (below). Current taxonomy. Flammulina jacquenetta (Hutton, 1883) — Hedley & Suter (1893: 643), Suter (1913: 678), Powell (1979: 314), Spencer et al. (2009: 215), but the genus level placement requires re-evaluation.	en	Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D., Spencer, Hamish G.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 174), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 475). Hutton’s descriptions of Patula jessica were based on more than one specimen, and he did not designate a holotype. Climo (1969: 193) incorrectly stated that the ‘ holotype’ was in Canterbury Museum, but this is not a valid lectotype fixation according to either Art. 74.5 or Art. 74.6 of the ICZN (1999) Code, because he was aware that the type material consisted of more than one specimen, and did not explicitly indicate that he was selecting a particular specimen to serve as the name-bearing type. Three paralectotype lots of P. jessica are mixed species assemblages: CMNZ M 72 contains four specimens that are conspecific with the lectotype and one specimen of Charopidae sp. 45 (sensu Spencer et al. 2009); CMNZ M 1058 contains ten specimens that are conspecific with the lectotype and three specimens of Charopidae sp. 45; and NMNZ M. 125544 contains eight specimens that are conspecific with the lectotype and two of Charopidae sp. 45.

Hutton submitted a description of Strobila leiodon to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 135), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 281). A description by Hutton (1884 b: 166, pl. 9, fig. P) of a radula of leiodon was probably based on the putative type material in CMNZ 2017.17.105 mentioned above. Hutton’s descriptions of S. leiodon were based on more than one specimen, and he did not designate a holotype. Climo (1969: 194) incorrectly stated that the ‘ holotype’ was in Canterbury Museum, but this is not a valid lectotype fixation according to either Art. 74.5 or Art. 74.6 of the ICZN (1999) Code, because he was aware that the type material consisted of more than one specimen, and did not explicitly indicate that he was selecting a particular specimen to serve as the name-bearing type. Strobila leiodon Hutton, 1882 is the type species of Ptychodon Ancey, 1888, by original designation. It is also the type species of Huttonella Suter, 1890 (non Huttonella Pfeiffer, 1856), by subsequent designation of Schileyko (2001: 937), and hence also of the replacement genus name Maoriana Suter, 1891 (see ICZN Article 67.8). The two last-mentioned genus names were treated as junior synonyms of Ptychodon by Schileyko (2001: 937). Current taxonomy.

AD3987E6FA2FFFCC50B6FF74FB47BB87.taxon	discussion	Remarks. Patula lucetta Hutton, 1884 is a subjective synonym of Helix (Patula) stokesi Smith, 1884, which was described from material collected in Wairarapa, North Island (e. g., Hedley & Suter 1893: 654; Suter, 1894 b: 268, 1913: 668; Cumber, 1961: 186; Powell, 1979: 323; Brook & Ablett 2019: 58). Hutton’s and Smith’s descriptions were published in May 1884 (see title page of the Transactions and Proceedings of the New Zealand Institute issue for 1883), and October 1884 (see Duncan 1937: 74), respectively, so Patula lucetta Hutton, 1884 has priority, as noted by Powell (1979: 323). The type material of this species was listed as being in Canterbury Museum, Christchurch, by Hutton (1898 – 1900: 9), and reported as missing by Freeman et al. (1997: 36) but has since been found. It comprises a mixed assemblage, containing five specimens of P. lucetta one of which (lectotype) is illustrated for the first time in pl. 3, fig. E, and two of Charopa coma (Gray, 1843). This is consistent with the observation by Murdoch (1899: 323), that Hutton’s original account of P. lucetta described the shell and animal coloration of his new species, and a radula of C. coma. Patula lucetta has been listed in genus Phenacohelix Suter, 1892 (e. g., Suter 1913: 668; Powell 1979: 323; Goulstone 2001: 57; Spencer et al. 2009: 216), in Phenacohelix (Neophenacohelix) Cumber, 1961 by Cumber (1961: 186), and in genus Neophenacohelix Cumber, 1961 by Marshall & Worthy (2017: 305), but preliminary results of a phylogenetic study (M. Kennedy & T. King unpub. data) indicate that it belongs in genus Phacussa Hutton, 1883. Patula lucetta has been recorded from both the North and South islands (e. g., Hedley & Suter 1893: 654; Suter 1894 b: 269, 1913: 669; Powell 1979: 323; Goulstone 2001: 59, fig. 12). However, Cumber (1961: 186) noted that there are morphological differences between populations on either side of Cook Strait and referred to the taxon as a species complex. The phylogenetic study referred to above found that COI sequences in populations from the North and South islands differed substantially (M. Kennedy & T. King unpub. data), indicating that they should be treated as separate species. Accordingly, Hutton’s name is used here for North Island populations only (below), and northern South Island populations that were previously referred to as lucetta are treated here as an unnamed sister species of lucetta, with a distribution from Marlborough Sounds to Nelson Lakes (AIM and NMNZ collection records). Records of lucetta from ‘ Greymouth (R. Helms) ’ by Hedley & Suter (1893: 654), Suter (1894 b: 269, 1913: 669) and Cumber (1961: 188) were based on mislocalised material (i. e., NMNZ M. 275314).

There has been confusion over the identity and distribution of Charopa miranda Hutton, 1883, as indicated in synonymies by Marshall & Barker (2008). In order to stabilize the nomenclature the last-mentioned authors designated a lectotype of miranda (CMNZ M 12780), illustrated here in pl. 3 fig. F, which they also designated as a neotype of Helix granum Pfeiffer, 1857, thus making Charopa miranda Hutton, 1883 a junior synonym of the latter taxon.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 179), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). Locality details listed by Hutton (1883 g: 476, 1884 b: 179) indicate that the original description of Amphidoxa perdita was based on a type series that included material collected in Auckland by Thomas Cheeseman and in Greymouth by Richard Helms. A lectotype is designated here from the Auckland material (CMNZ M 275.1), and is illustrated in pl. 3, fig. H. This species has a very wide distribution in New Zealand (below). From Pilsbry (1893 [in 1893 – 1895]: 18) and Hedley & Suter (1893: 643) onwards, perdita has generally been assigned to Flammulina Martens, 1873 at subgenus or genus level. Current taxonomy.

AD3987E6FA12FFF050B6FAF5FCCDBDBB.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 181), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 477). There has been considerable confusion over the identity and distribution of Charopa planulata, as indicated by synonymies of Climo & Mahlfeld (1998) and Marshall & Barker (2008: 83, 85, 115, 116). Following misidentifications by Pilsbry (1892 [in 1892 – 1893]: 67; 1893 [in 1893 – 1895]: pl. 3, figs. 4 – 6), planulata was generally assigned to Allodiscus Pilsbry, 1892 at subgenus or genus level, and Hutton’s species name was misapplied to several different taxa, and interpreted as having a wide distribution in New Zealand (e. g., Suter 1913; Powell 1979). Climo & Mahlfeld (1998) stated that all previous records of planulata except the type material were of other species, and they reassigned Charopa planulata Hutton, 1883 to genus Chaureopa Climo, 1985. Charopa planulata Hutton, 1883 is possibly conspecific with Chaureopa microumbilicata Climo, 1985. Type material of the former taxon has a shell of up to 2.7 mm diameter at 4.0 whorls, with a slightly elevated spire, an almost closed umbilicus, teleoconch sculpture of crisp, closely-spaced, sigmoidal radial ribs, and a smooth, glossy protoconch of 1.3 – 1.4 whorls and maximum diameter of 0.53 – 0.60 mm. Chaureopa microumbilicata, with a holotype from Kauaeranga Valley, Thames, attains a slightly larger size than the type material of planulata (max. diameter of 3.15 mm at 4.6 whorls), but has similar shell shape and teleoconch sculpture. Shells of microumbilicata generally have a narrowly open umbilicus c. 8 – 13 % of maximum shell diameter (e. g., AIM MA 84935, MA 96690, NMNZ M. 62443, M. 62444, M. 78793, M. 97634, M. 186395, M. 186508, M. 301462), but some populations in Hunua Ranges and Thames, southeast of Auckland, contain shells that have the umbilicus almost closed, as in the type material of planulata (e. g., AIM MA 84932, MA 97021, NMNZ M. 78794). Protoconch size in microumbilcata is also variable, ranging from 0.54 – 0.74 mm in maximum diameter, and 1.3 – 1.7 whorls. The two taxa have overlapping distributions: planulata was described from material collected in Auckland; microumbilicata has a sparse distribution in the northeastern North Island between Waiwera, north of Auckland, and Bay of Plenty (AIM and NMNZ collection records).

AD3987E6FA13FFF050B6FC31FC33B9E9.taxon	discussion	Remarks. Hutton submitted a description of Thalassia (?) propinqua to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 137), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 281). A description by Hutton (1884 b: 169, pl. 10, fig. G, pl. 11, fig. V) of a jaw and radula purported to be from propinqua was based on a specimen from Southland collected by G. M. Thomson (i. e., CMNZ 2017.17.82) that is not type material of, or conspecific with, Thalassia propinqua Hutton, 1882. From Pilsbry (1892 [in 1892 – 1893]: 72) onwards propinqua has generally been assigned to Thalassohelix Pilsbry, 1892 at subgenus or genus level, and it has been interpreted as having a wide distribution in New Zealand, between Auckland in the North Island, and the southern South Island (e. g., Hutton 1884 c: 203, Hedley & Suter 1893: 636, Suter 1913: 631, Powell 1979: 318). However, preliminary results of a phylogenetic study indicate that propinqua belongs in genus Therasia Hutton, 1883; the genetic data and examination of museum collections indicate that it has a distribution spanning the south-eastern North Island and north-eastern South Island, only (M. Kennedy unpub. data). Taxonomy. Here treated as Therasia propinqua (Hutton, 1882) n. comb.	en	Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D., Spencer, Hamish G.

Powell (1948: 276) erected the genus Therasiella for T. tamora and two other species, noting that they differed from typical Therasia in having membranously plaited epidermal processes, and a smaller number of teeth in the radula. In a taxonomic review of Therasiella, Cumber (1967: 69) noted that tamora differed from other species in this genus in having “ oblong, bluntly rounded extensions of the periostracal plaits together with the absence of any fine processes on these plaits ”. These periostracal processes are commonly damaged or lost during life or subsequent preservation of shells, and although depicted in illustrations by Pilsbry (1892 [in 1892 – 1893]: pl. 22, figs. 49 – 51) and Suter (1915: pl. 9, figs. 7, a, b), they are absent from the three extant type specimens of T. tamora.

This species was incorrectly identified as Patula coma (Gray, 1843) by Hutton (1882 h: 150 — see Hutton 1883 d: 134). Hutton (1884 c: 193), Hedley & Suter (1893: 656) and Suter (1894 b: 268, 1913: 724) interpreted P. tapirina as having a wide distribution in New Zealand, from Auckland, in the North Island, to Rakiura / Stewart Island.

Therasia thaisa Hutton is the type species of Therasia Hutton, 1883, by subsequent designation of Pilsbry (1893 [in 1893 – 1895]: 15). Pilsbry had earlier (1892) nominated Nanina celinde Gray, 1850 as the type of Therasia, but this was invalid as the latter species was not in Hutton’s original list. There has been confusion over the identity and distribution of T. thaisa: it has variously been interpreted as having a wide distribution in New Zealand, from Auckland, in the North Island, to the southern South Island (e. g., Hutton 1884 c: 202, Hedley & Suter 1893: 641, Suter 1894 b: 247); or being present throughout the South Island and on Rakiura / Stewart Island, only (e. g., Suter 1913: 661, Powell 1979: 316). Preliminary results of a phylogenetic study, and examination of museum collections, indicate that the distribution of T. thaisa Hutton, 1883 is in fact restricted to the southern South Island, Rakiura and Whenua Hou / Codfish Island (M.

AD3987E6FA17FFF750B6FD19FE23BF5F.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 175), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 475). There has been confusion over the identity and distribution of Patula timandra: it was treated a valid species by Hutton (1884 c: 192), Pilsbry (1892 [in 1892 – 1893]: 84) and Suter (1894 a: 128, 1894 b: 258); and was incorrectly listed as a junior synonym of Helix varicosa Pfeiffer, 1853 [= H. varicosa Reeve, 1852] by Suter (1892 e: 293), Hedley & Suter (1893: 651), Climo (1969: 201), Powell (1979: 306), Marshall (1995: 498), and Freeman et al. (1997: 37); and as a junior synonym of Helix tau Pfeiffer, 1861 by Murdoch (1899: 321) and Suter (1913: 687). Pilsbry (1892 [in 1892 – 1893]) included three figures of putative P. timandra, one of which was drawn by Henry Suter (pl. 24, fig. 21), and the other two by Pilsbry himself (pl. 24, figs. 22, 23), as indicated in the figure captions (p. 304). The illustration by Suter was probably based on a specimen from the type series in the Canterbury Museum (see Hyde 2017: 102), whereas the shell (s) drawn by Pilsbry was probably from a (mixed?) lot of three specimens that, according to ANSP catalogue details, had been collected in the South Island, New Zealand, by Suter (i. e., ANSP 63797). The illustration of Pilsbry (1892 [in 1892 – 1893]: pl. 24, figs. 21) shows that timandra has three apertural lamellae, as does an illustration and accompanying description by Suter (1894 a: 128, pl. 15, fig. 13), indicating that this species belongs in the genus Fectola Iredale, 1915, though Climo (1978 a) did not mention it in his taxonomic review of this genus-group. Nine valid species of Fectola are known from New Zealand, two of which, F. infecta (Reeve, 1852) and F. tau (Pfeiffer, 1861) [= F. trilamellata Climo, 1978] have three apertural lamellae arranged like those in Pilsbry’s and Suter’s illustrations (Climo 1978 a, 1989; Brook & Ablett 2019). The description by Hutton (1884 b: 175) of a shell with a flat or slightly convex spire, the number and arrangement of apertural lamellae shown in Suter’s illustration of putative type material (Pilsbry 1892 [in 1892 – 1893]: pl. 24, fig. 21), and the fact that this species was described from material collected at Auckland, indicates that Patula timandra Hutton, 1883 is probably conspecific with Fectola infecta (Reeve, 1852). The latter species is widely distributed in the northern North Island from Houhora south to Taranaki, Ruapehu and Hawke’s Bay (Climo 1978 a: fig. 3; 1989: fig. 3; AIM and NMNZ collection records). We have not examined the specimen of ‘ Patula timandra ’ that was illustrated by Pilsbry (1892 [in 1892 – 1893]: pl. 24, fig. 22), but if the locality details for ANSP 63797 mentioned above are correct we expect that it would prove to be F. tau, which has a distribution spanning the northern South Island and southern North Island according to Climo (1978 a, 1989 — as F. trilamellata).

Hutton submitted a description of Phrixgnathus celia to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 176), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). This is a morphologically variable species, with shells differing in spire elevation, spire angle and umbilical width, both within and between local populations. This is evident in the type material, which was collected by Hutton himself. The lectotype, illustrated here for the first time in pl. 5, fig. B, has a relatively high spire compared to some paralectotypes. There has been considerable confusion over the taxonomy and distribution of P. celia. Initially, Hutton (1882 h: 153 — see Hutton 1884 b: 176) incorrectly identified material of this species as Helix fatua Pfeiffer, 1857, which is in fact a subjective junior synonym of Therasiella celinde (Gray, 1850) (Brook & Ablett 2019: 43). Hutton (1884 c: 197) recorded P. celia from the South Island and southern North Island, and Hedley & Suter (1893: 648), Suter (1894 b: 279, 1913: 749) and Powell (1979: 326) recorded it from Rakiura / Stewart Island, South Island, and North Island south of Auckland. Examination of museum collections indicates that previous records of P. celia from the North Island were in error, and preliminary genetic analyses indicate that putative South Island records comprise a complex of several species (M. Kennedy unpub. data). On present knowledge celia sensu stricto appears to have a distribution restricted to southern South Island, Whenua Hou / Codfish Island, Rakiura and nearby islands (below). Morphologically similar taxa in northern South Island differ substantially genetically from typical celia, and evidently represent separate species. Examination of type material indicates that Laoma (Phrixgnathus) liratula Suter, 1909, which was based on material from Stewart Island (i. e., NMNZ M. 88227, M. 88228), and Thalassohelix pygmaea Suter, 1913, based on material from Woodhaugh, Otago [= Dunedin] (i. e., NMNZ M. 125165), are subjective junior synonyms of Phrixgnathus celia Hutton, 1883. Laoma (Phrixgnathus) celia alboviridis Suter, 1913, based on material from ‘ Mt Alfred, Otago’ (i. e., NMNZ M. 88225, M. 88226), is very similar morphologically to typical celia, and may also be a synonym. Laoma (Phrixgnathus) celia levis Suter, 1913, which is based on material from Pipiriki, Wanganui River (i. e., NMNZ M. 88134), was listed as a junior synonym of P. celia Hutton, 1883 by Powell (1979: 326), but appears to us to be a separate species that has a distribution between Whanganui and Port Waikato, western North Island. Powell (1979: 330) suggested that Laoma (Phrixgnathus) trailli Suter, 1909, which was based on material from an unknown location (NMNZ M. 83445), “ looks like a large form of liratula ”, but examination of type material indicates that the two are clearly different species. Phrixgnathus celia was incorrectly listed as the type species of Phrixgnathus Hutton by some authors (e. g., Pilsbry, 1893 [in 1893 – 1895]: 9, Suter 1913: 738, Thiele 1931 [in 1929 – 1935]: 567, Solem 1959: 81, Zilch 1959 [in 1959 – 1960]: 205, Powell 1979: 325, Spencer & Willan 1996: 41, Schileyko 2002: 1048).

AD3987E6FA1BFFF850B6FD89FAE5B9E9.taxon	discussion	Remarks. Hutton submitted a description of Endodonta marina to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 176), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). Hutton differentiated this species from the morphologically similar Endodonta nerissa Hutton, 1883, which he described from the same type locality (see below), on the basis of the number and arrangement of lamellae inside the aperture of the shell. Suter (1892 d: 283) examined populations of putative marina and nerissa from Mt Wellington, Auckland, and Forty-Mile Bush, Wairarapa, and concluded that these two species were synonyms. This interpretation was followed by Hedley & Suter (1893: 646), Suter (1894 b: 274, 1913: 735) and others, who recorded marina sensu lato as having a wide distribution in the North Island south of Auckland, and in Marlborough Sounds, South Island (e. g., Powell 1979: 325). However, Climo et al. (2020) reinstated nerissa as a valid species, noting that there are consistent morphological differences between it and marina. They recorded marina as having a relatively wide distribution in the northern North Island between Hokianga and Mt Pirongia (Climo et al. 2020: 78, fig. 14 B), but examination of material in museum collections, and preliminary genetic analyses (M. Kennedy & T. King unpub. data), indicate that this refers to a complex of species. The distribution of marina is here interpreted as being restricted to western Northland and Auckland regions only (below), pending further study. Specimens in CMNZ M 1049, with catalogue details ‘ Laoma marina Hutton, Auckland (old number ZS 772) ’, were treated as primary type material (syntypes) of Endodonta marina Hutton, 1883 by Freeman et al. (1997: 32), but this does not stand scrutiny. This lot contains one dry shell matching Hutton’s description of marina (M 1049.2, see Climo et al. 2020: fig. 2 F), and three shells (M 1049.1, M 1049.3, M 1049.4, see Climo et al. 2020, figs. 2 C – E) that match the original description of Endodonta nerissa Hutton, 1883. The fact that this is a mixed lot clearly indicates that it was not part of Hutton’s type series of marina, and the species identification suggests that it postdates Suter’s (1892 d: 283) synonymy of E. marina and E. nerissa.

AD3987E6FA18FFFD50B6FC12FBECBEC0.taxon	discussion	Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 177), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). These descriptions were based on one or more specimens reportedly collected from Whanganui and sent to Hutton by T. W. Kirk. Subsequently there has been confusion over the identity and distribution of Phrixgnathus phrynia. Hedley & Suter (1893: 649) and Suter (1894 b: 279) recorded it from several North Island localities between Whangarei and Whanganui; and Suter (1913: 756), Dell (1954 b: 147) and Powell (1979: 329) recorded it as being widely distributed in the North and South islands, and present also on Rakiura / Stewart Island. However, examination of museum collections indicates that it actually has a much narrower distribution (see below). Phrixgnathus acanthinulopsis Suter, 1891, based on material from Hooker Valley, Mt Cook (i. e., NMNZ M. 88018), was listed as a junior synonym of P. phrynia Hutton, 1883 by Suter (1913: 755), Dell (1954 b: 147) and Powell (1979: 329), but these two taxa differ morphologically and genetically (M. Kennedy & T. King, unpub. data), and in our opinion are separate species. Laoma (Phrixgnathus) phrynia var. major Suter, 1897, based on material from Stewart Island (i. e., NMNZ M. 125167), was listed as a junior synonym of P. phrynia Hutton, 1883 by Dell (1954: 147) and Powell (1979: 329), but examination of type material indicates that these also are separate species, and that the former is a synonym of Phrixgnathus flemingi stewartensis Dell, 1954. Phrixgnathus oconnori Powell, 1941, based on material from Pirinoa [Wairarapa] (i. e., AIM MA 70621), is a subjective junior synonym of P. phrynia Hutton, 1883, as noted by Powell (1979: 329).

AD3987E6FA1EFFFC50B6FEA9FB0CBDD7.taxon	discussion	Remarks. Hutton submitted a description of Microphysa (?) pumila to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 134), and was pre-empted by his brief description of Microphysa pumila in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 281). There has been confusion over the nomenclature of this taxon in New Zealand, and it has appeared under several different species names. Examination of type material indicates that M. pumila is conspecific with Helix caputspinulae Reeve, 1852 and H. epsilon Pfeiffer, 1853, both based on the same type material from New Zealand in the Cuming collection (NHMUK 1962724: Brook & Ablett 2019: 69), and with Paralaoma ambigua Iredale, 1913 (CMNZ M 4974) and P. raoulensis Iredale, 1913 (CMNZ M 5000), from Raoul Island, Kermadec Islands. Reeve’s species name caputspinulae was misapplied by some (e. g., Suter 1913: 715, Climo 1970: 330, Powell 1979: 309) to material of Helix eta Pfeiffer, 1853, and H. caputspinulae was also designated as the type of subgenus Subfectola, Powell, 1939, based on material of H. eta Pfeiffer, 1853 (see Climo 1981: 9, Goulstone 1995: 63). Climo (1981: 9, 10) re-examined the type material of H. caputspinulae Reeve, 1852, and noted that it was conspecific with Paralaoma raoulensis Iredale, 1913, the type of genus Paralaoma Iredale, 1913 (subsequent designation of Iredale 1937). Roth (1987: 95, 96) interpreted Paralaoma caputspinulae (Reeve, 1852) as being a weedy species that had a wide global distribution and had been described under many different names. He noted that Helix pusilla Lowe, 1831, based on specimens from the Atlantic island of Madeira, was the earliest published name of this species, but was pre-occupied by H. pusilla Fleming, 1828. Falkner et al. (2002: 117 – 118) treated P. caputspinulae (Reeve, 1852) as a junior synonym of Paralaoma servilis (Shuttleworth, 1852), which had been described from material from Canary Islands (see Neubert & Gosteli 2003: 49, pl. 15, fig. 3), but this decision requires re-evaluation (see below). As presently interpreted, the distribution of P. servilis includes New Zealand (Kermadec, Three Kings, North, South, Rakiura / Stewart and Chatham islands), Australia, parts of Europe, Middle East, Africa, Asia, North and South America, Jamaica, Macaronesia, Réunion, Indonesia, Hawai’i, and Easter Island (e. g., Gittenberger et al. 1980 and Roth 1986 — as Punctum pusillum; Smith, 1992 and Griffiths & Florens 2006 — as Paralaoma caputspinulae; Neubert 1998 — as Toltecia pusilla; Hausdorf 2002, Christensen et al. 2012, Welter-Schultes 2012, Gittenberger et al. 2020 — as Paralaoma servilis). Paralaoma caputspinulae (= P. servilis?) is definitely native to the New Zealand region, having been found in Holocene fossil assemblages in North Island, Rēkohu / Chatham Island and Rakiura that predate human occupation (Brook 1999 b, c; F. Brook unpub. data). Preliminary results of a phylogenetic study of New Zealand Punctidae indicate that Paralaoma of authors is polyphyletic, and that there appears to be one species only of this genus in the Recent New Zealand fauna; the various other New Zealand species assigned to Paralaoma (e. g., by Powell 1979; Spencer & Willan 1996; Spencer et al. 2009) are not congeneric (M. Kennedy unpub. data). A species closely resembling P. caputspinulae is evidently also native to Norfolk Island, having been recorded from Holocene fossil assemblages that predate human settlement of this island (Neuweger et al. 2001 — as Paralaoma duncombei Iredale, 1945). Several punctid taxa described from Tasmania and eastern mainland Australia also resemble P. caputspinulae, and have been treated as synonyms of it (e. g., by Smith and Kershaw 1979: 264, 265; Smith 1992: 282, 283; Stanisic et al. 2010: 566). However, Stanisic et al. (2018: 126, 127) reinstated some of these as separate, probably endemic, species of Paralaoma, noting their “ occurrence in often remote habitats of native forest where it is difficult to envisage anthropogenic introduction ”. If correct, this would indicate that the genus Paralaoma is native to Australasia, with multiple species in mainland Australia and a single species in the New Zealand region. Interestingly, a North American punctid species that Roth (1987) identified as P. caputspinulae has been recorded from a wide range of environments in western USA and Canada, including remote, undisturbed, montane forest habitats where an anthropogenic origin is improbable. It has been considered by some authors to be indigenous to this continent (e. g., Roth 1986 — as Punctum pusillum; Metcalf & Smartt 1997: 39 — as Paralaoma caputspinulae), whereas others have suggested that it had been introduced there (e. g., Christensen et al. 2012: 5 — as P. servilis). Bequaert & Miller (1973: 153 — as Punctum conspectum) and Roth (1986: 23) stated that this species was not known fossil in North America, but Metcalf (1997: table 5 — as Paralaoma caputspinulae) recorded it from Quaternary alluvial / colluvial deposits in Sacramento Mountains, New Mexico, which suggests that it is indeed native. However, whether it is conspecific with P. servilis (or P. caputspinulae) remains to be determined. To date, species identifications and biogeographic interpretations of Paralaoma servilis and its many putative synonyms have been based mainly on comparison of shell morphological characters, but molecular studies will be required to reliably determine the global systematics and phylogeography of this species and its congeners. Taxonomy. Presently interpreted as a subjective junior synonym of Paralaoma servilis (Shuttleworth, 1852) (e. g., Brook & Ablett 2019: 69, Gittenberger et al. 2020: 78), but this requires re-evaluation.	en	Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D., Spencer, Hamish G.

AD3987E6FA1FFFFF50B6FBDDFDF3BE8B.taxon	discussion	Remarks. The original description of this species was based on one or more specimens collected by Hutton himself. He submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 177), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). Suter (1913: 762) noted “ the only specimen I have seen is the type ”. Powell (1979: 330) listed titania as a species of uncertain status, noting “ the writer has not seen the holotype, the only known specimen. From Suter’s (1913, p. 762) description and figure (1915, pl. 30, fig. 10) the specimen is obviously abnormal in its coiling, and may prove to be [Phrixgnathus] celia ”. However, examination of type material indicates that titania and celia are separate species, differing in umbilical width, spire profile, teleoconch microsculpture and colour pattern. Phrixgnathus titania was recorded from Dunedin only by Suter (1913: 762) and Powell (1979: 330), but museum collection records indicate that it has a wider distribution in southeastern South Island, which in part overlaps that of celia (see above).

AD3987E6FA1CFFFE50B6FAF2FDD5B884.taxon	discussion	Remarks. Hutton submitted descriptions of two new species of Rhytida from Greymouth, R. citrina and R. patula, to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 139), and was pre-empted by brief descriptions of both taxa in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 282). A description by Hutton (1884 b: 167, pl. 10, fig. R) of a radula of citrina was possibly based on CMNZ 2017.17.9 mentioned above. Suter (1913: 772) stated that the type material of R. citrina in the Canterbury Museum consisted of three shells, the largest of which had a maximum diameter of 7.75 mm. This type material was apparently subsequently lost. Powell (1946: 129) stated that he had “ not seen the types which Dr. Falla has been unable to locate in the Canterbury collections ”, but mentioned the existence of “ two of Hutton’s Greymouth specimens [of citrina] in the Canterbury Museum ”, which he reported as having major diameters of 8.5 mm and 5.5 mm, respectively. These two specimens, both juvenile shells, correspond to lots CMNZ M 1416 and M 5456 [ex M 1416], respectively. Freeman et al. (1997: 30) listed these two lots, and CMNZ M 123 [ex ZS 818], as syntypes of R. citrina, but this does not stand scrutiny. The last-mentioned lot is from Buller River, which is not the type locality of citrina. The collector is not stated in the CMNZ molluscan catalogue but was probably Julius von Haast (see Hutton (1884 c: 208). The catalogue indicates that lots M 1416 and M 5456 from Greymouth, along with M 1417 from Balclutha, were all identified as citrina and were included in ‘ old No. 122 ’ in Hutton’s collection. Hutton’s original labels for this material have been lost or destroyed. The register does not state who the material from Greymouth was collected by, and there is no indication that these two specimens are primary type material of citrina. The specimens from Balclutha (M 1417) were evidently collected by Hutton himself, and were identified as R. patula by Hutton (1884 b: 167, 1884 c: 208), and R. otagoensis by Powell (1930). Hutton (1882 p: 282, 1883 d: 139, 1884 b: 167, 1884 c: 208) described citrina and patula as differing from one another in shell and animal colouration, and radula features, but there has been confusion over the identity and distributions of these two taxa. Hutton (1884 c: 208) recorded citrina from Greymouth and Buller River, and patula from Greymouth and Balclutha, respectively. Suter (1913: 772) treated them as separate species, but noted that the type material of R. citrina consisted of juvenile shells only, and observed that “ it is not easy to separate this species from R. patula by shell characters alone ”. Powell (1946: 129) considered that they were separate species with partly overlapping distributions, noting that “ from Greymouth to the Buller River two forms occur, a reddish-brown one with a greatly accelerated last whorl, which is definitely patula, and a yellowish-olive one with closely coiled whorls, which is almost certainly the adult of citrina ”. His interpretation of citrina was based mainly on the specimen from Buller River in CMNZ M 123, mentioned above. Powell (1946: 129, text fig. C 1) described this specimen, which has since been badly damaged, as “ an adult or nearly so, of 18.5 mm diameter, with “ closely coiled whorls and the yellowish-olive coloration of citrina ”. He recorded R. citrina from Maruia Springs, Rewanui, and Lake Kaniere, in addition to Hutton’s records from Greymouth and Buller River. Parkinson (1979: 10), Powell (1979: 345), Spencer & Willan (1996) and Spencer et al. (2009) all listed R. citrina and R. patula as separate species, though the firstmentioned author noted that citrina was rather poorly known. Conversely, Efford (1998: 11) cast doubt on the putative differences in shell coloration and coiling between R. citrina and R. patula, noting that he was unable to detect these “ once allowance is made for age-related changes in shell shape ”. He suggested that most previous records of citrina were referable to R. patula, but that some may have been based on R. perampla Powell, 1946. Recent field surveys and preliminary results of a phylogenetic study (F. Brook & M. Kennedy unpub. data) indicate that there are two species of Rhytida in the vicinity of Greymouth that correspond to Hutton’s citrina and patula, respectively. Given that the whereabouts of the type material of the former is not known, and in order to prevent further confusion over the identity of this species and stabilise the nomenclature, we designate a specimen from Mt Davy, Rewanui, illustrated in pl. 6, fig. D (NMNZ M. 329343), as the neotype of Rhytida citrina Hutton, 1882. As interpreted here R. citrina is considerably more widely distributed in the northwestern South Island than was previously recognised (below).

AD3987E6FA1DFFE150B6F8ECFD9BBD64.taxon	discussion	Remarks. Hutton submitted a description of Gerontia cordelia to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 178), and was pre-empted by his brief description of Gerentia [sic] cordelia in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). These descriptions were based on one or more specimens that were putatively collected by Thomas Cheeseman in Titirangi, West Auckland. However, the locality details are probably incorrect as there have been no subsequent records of this species from the Auckland region (e. g., Powell 1952: 167, AIM and NMNZ collection records). Early workers variously assigned G. cordelia to family Charopidae (e. g., Hutton 1884 c: 200), Helicidae (e. g., Pilsbry 1892 – 1893, Suter 1894 b), Phenacohelicidae (e. g., Suter 1913) and Flammulinidae (e. g., Powell 1937). Powell (1952: 167) recognised that G. cordelia was a paryphantid [i. e., = family Rhytididae], and designated it as the type species of subgenus Delouagapia Powell, 1952, in genus Delos Hutton, 1904. Delouagapia has generally been treated as a separate genus following Climo (1977: 61). Current taxonomy. Delouagapia cordelia (Hutton 1883) — Climo (1977: 61), Spencer et al.

AD3987E6FA02FFE350B6FC4DFC70BFF5.taxon	discussion	Remarks. Described in genus Paryphanta Albers, 1850, assigned to subgenus Powelliphanta by O’Connor (1945), and the latter treated as a full genus by Climo (1977: 60) and subsequent authors. Hutton’s (1888: 43 – 44) original description of the holotype of Paryphanta lignaria stated that it had a maximum diameter of about two inches (= c. 50 mm), a slightly-elevated spire “ forming an angle of about 135 o ”, and that the base had been mostly broken off, leaving the “ shape of the umbilicus and the aperture uncertain ”. The remaining part of the base was “ smooth and polished ”, in contrast to the apical surface, which was “ finely irregularly granulated by deeply undulating impressed lines ”, and had a colour pattern of irregular “ dark reddish brown and pale brownish-yellow ” radial streaks. There are no published illustrations of the holotype. Pilsbry (1894: 31, pl. 1, figs. 1 – 3) illustrated a putative type specimen of lignaria, “ drawn by Mr. H. Suter ”. It is the larger one of two specimens in CMNZ M 690 that had been presented to Canterbury Museum by Dr Gaze in 1893 (i. e., entry for 14 August 1893 in CMNZ Accession Register for 1891 – 1933), and which was incorrectly listed as a ‘ cotype’ of lignaria by Hutton (1898 – 1900: 7), and as the ‘ type’ by Suter (1913: 784). The entry in the Accession Register does not state where the specimens in M 690 were collected, and the original label has been lost or destroyed. A handwritten note associated with M 690 states: “ Note by A. W. B. Powell pasted to previous mount: Paryphanta unicolorata Powell 1930. Mt Frederick locality probably correct but omit reference to saddle between Mokihinui and Lyell Rivers. Certainly not the type of lignaria which measures 2 ins. in greatest diameter (Hutton 1888), 21.7.1930 ”. Although not stated explicitly, Powell’s note suggests that the specimens in M 690 were originally labelled as being from two separate localities. The two specimens differ from Hutton’s description of lignaria, and from Paryphanta unicolorata Powell, 1930 (see comments on the latter taxon below), in being smaller, and having weakly calcified shells with a smooth, shiny apical surface. From shell characters they appear to belong to the group of Powelliphanta patrickensis (Powell, 1949) and related species (see Walker 2003, Walker et al. 2008), which was referred to as the Powelliphanta Kawatiri complex by Daly et al. (2019). Hutton (1900: 22, pl. 2) and Suter (1915, pl. 32, fig. 12, a, b) illustrated a shell from ‘ Mount Rochfort, near Westport’, which they identified as Paryphanta lignaria. This specimen (i. e., CMNZ M 694) was of a similar size to the holotype of lignaria, but differed in having a more elevated spire and being “ of a yellowish-brown or luteous colour, the brown bands being obsolete ” (Hutton, 1900: 22). In the first of a series of papers on the taxonomy of New Zealand Paryphantidae (now Rhytididae), Powell (1930: 42 – 43) interpreted the distribution of typical lignaria as extending from the north side of the Mokihinui River to Karamea. He included the Mt Rochfort taxon in a new species, Paryphanta unicolorata Powell, 1930, with a type locality at Seddonville, and a distribution south of the Mokihinui River (see also Powell 1936: pl. 10). The latter taxon was differentiated from lignaria on shell colour, being uniformly olive-brown rather than radially striped as per Hutton’s original description of lignaria. Powell (1941: 239, 253) inferred that the type material of lignaria was probably lost, but later (Powell 1946: 106; 1949: 348) suggested that “ an unlabeled specimen from the collection of the late Mr. Boswell of Westport ” (i. e., AIM MA 71492) may be the missing holotype of lignaria, albeit without providing any convincing evidence in support of this. Powell (1949: 350) designated a shell that he had illustrated previously (Powell, 1930: pl. 4, fig. 1) as a neotype. It is part of a lot of 20 specimens (AIM MA 64520) from near St. Helens, Mokihinui, c. 25 km NW of the type locality of lignaria cited by Hutton (1888). Powell (1949: 347 – 357) gave a detailed account of the taxonomic history of Paryphata (Powelliphanta) lignaria sensu lato. He inferred that the type locality of lignaria given by Hutton (1888) was incorrect, and that “ Hutton’s locality for his 1900 record of ‘ lignaria ’ [i. e., from Mt Rochfort] is evidently erroneous, the specimen being a unicolorata, probably from the Seddonville area ”. In the same paper he reinterpreted the distribution of lignaria sensu stricto as being restricted to coastal hill country extending north from the Mokihinui River mouth to Kongahu Point and Corbyvale, and recognised several subspecies from adjoining areas (including lignaria unicolorata), and one from the Leslie and upper Karamea rivers, based mainly on differences in shell colouring (Powell 1949: 350, pl. 67). Most subsequent workers have followed Powell’s interpretations of the lignaria group of subspecies (e. g., Parkinson 1979, Powell 1979, Meads et al. 1984, Walker 2003), but Climo (1978 b) proposed an alternative classification in which lignaria sensu lato of Powell was treated as a subspecies of Powelliphanta hochstetteri (Pfeiffer, 1862). Genetic studies by Walker (2003: 200), Trewick et al. (2008), and Buckley et al. (2014) indicated that Powell’s lignaria group is monophyletic and not closely related to hochstetteri. The last-mentioned study also found that there was a lack of monophyly in mitochondrial COI sequences among Powell’s subspecies of lignaria, and that only one subspecies, Powelliphanta lignaria rotella Powell, 1938, had a distinct nuclear genotype as determined from microsatellite data. Powell (1949: 348) noted that following the original description there had been no further valid records of lignaria from the vicinity of the Lyell-Mokihinui Saddle. That is apparently still the case, and a brief search carried out during the present study failed to find any snails or empty shells of this species in beech and Dracophyllum forest on and around the saddle. However, surveys over the last few decades have shown that the distribution of Powelliphanta lignaria unicolorata (Powell, 1930) extends up the Mokihinui River South Branch to within a few kilometers of the Lyell-Mokihinui Saddle (Walker 2003: 121, pl. 39). Although shells of unicolorata are generally a plain olive-brown in colour, some have irregular, reddish-brown radial streaks matching Hutton’s original description of lignaria (e. g., NMNZ M. 77190, M. 125507, M. 308311, and this, along with the geographic proximity of unicolorata to the type locality of lignaria, indicates that Parphanta unicolorata Powell, 1930 is probably a synonym of Paryphanta lignaria Hutton, 1888. If this interpretation is correct a new subspecific name will be required for the population on the coastal range north of Mokihinui River, which was treated as lignaria sensu stricto by Powell (1949: 350, 1979: 336), Meads et al. (1984: 295), Walker (2003: 111, pl. 35) and others. This eventuality was anticipated by Powell (1946: 106), who noted that the identity of lignaria “ cannot be finalized until topotypes of Hutton’s species are obtained, but the indications are that …. the Mokihinui-Karamea coastal form will require to be named, my nomination of a St. Helens specimen as neotype becoming void ”. During the present study a previously unreported population of Powelliphanta in the Kawatiri complex of Daly (2019) was found in alpine shrub-tussockland on the Lyell Range, above the Lyell-Mokihinui Saddle, confirming a prediction by Powell (1949: 348). The shells differ from Hutton’s description of lignaria in their smaller adult size (maximum shell diameter of c. 44 mm), and smooth, shiny surface on both the spire and base, and may be conspecific with the larger specimen in CMNZ M 690. A record of Powelliphanta lignaria unicolorata further north on Lyell Range by Walker (2003: pl. 39) was an error based on misidentification of a species of the Kawatiri complex (K. Walker pers. comm. 2019). With regard to Hutton’s (1900: 22, pl. 2) record of putative Paryphanta lignaria from Mt Rochfort, it is possible that the illustrated specimen in CMNZ M 694 was in fact from this locality as originally stated (i. e., not from the Seddonville area, as suggested by Powell 1949: 352), and represents a separate taxon that has not been recollected there, and may now be extinct. The shell differs from typical unicolorata in having a more elevated spire, and a more rapidly descending final whorl, and in these regards it shows similarities with illustrations of Powelliphanta “ Buller River ” by Walker (2003: 130, pl. 42).	en	Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D., Spencer, Hamish G.

AD3987E6FA00FFE550B6FDC3FD70BC22.taxon	discussion	Remarks. Hutton submitted a description of Rhytida patula to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 139), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 282). A description by Hutton (1884 b: 167, pl. 10, fig. Q) of a radula of patula was probably based on the putative type material in CMNZ 2017.17.59 mentioned above. As noted in the preceding species entry, Hutton (1883 d: 139) differentiated R. patula from R. citrina, both described from material from Greymouth, on the basis of shell and animal coloration, and radula details. From the start there has been confusion over the identity and distribution of both species. Powell (1946: 127) noted that type material of R. patula at CMNZ comprised six ‘ co-types’ and he selected the largest specimen, which most closely matched the shell dimensions given by Hutton (1883 d: 138), as the lectotype, which is illustrated here in pl. 6, fig. F. Re-examination of this type series indicates that it is a mixed lot that contains two different species, a fact evidently not recognized by Hutton and other workers. One paralectotype (M 121.5) is conspecific with the lectotype of R. patula, three match the neotype of R. citrina Hutton, 1882 and are interpreted here as that species (M 121.1 – M 121.3), and one small juvenile shell was indeterminate (M 121.4). One of the paralectotypes identified as R. citrina, M 121.3, is illustrated here in pl. 6, fig. E. Records of R. patula from Balclutha by Hutton (1884 b: 167, 1884 c: 208), Hedley & Suter, (1893: 630) and Suter (1894 b: 286, 1913: 777), based on CMNZ M 1417, refer to a different species, Rhytida otagoensis Powell, 1930. Powell (1946: 127, 1979: 345) recorded R. patula from several localities on the West Coast of the South Island between Whanganui Inlet and Lake Kaniere, and Parkinson (1979: 10) stated that this species was distributed over “ most of the West Nelson block ”. Efford (1998: 36, fig. 4 J) mapped R. patula as having a wide distribution in the northwestern South Island, from Cape Farewell south to Shantytown (south of Greymouth) and Lewis Pass, albeit noting that this could be a complex of related species. Preliminary results of a phylogenetic study (M. Kennedy & T. King unpub. data) confirm this suspicion, and indicate that R. patula has a more restricted distribution than previously recognised (see below). Assigned to genus Rhytida Albers, 1860 by Hutton (1882) and subsequent authors, but this placement requires re-evaluation (M. Kennedy & T. King unpub. data). Current taxonomy.

The original label of the type material of Limax molestus at OMNZ has been lost or destroyed, but transcribed details indicate that this material was collected and identified by Hutton himself. A specimen of L. molestus that was mentioned by Cockerell & Collinge (1893: 201) as being “ in the British Museum … from Dunedin (Otago Univ. Mus.) ” is possibly a syntype (NHMUK 1886.11.18.26). It was evidently sent to London as an exhibit in the Colonial and Indian Exhibition of 1886 and was subsequently purchased by the British Museum. There has been confusion over the identity L. molestus. Hutton (1879: 331) noted that it was “ closely allied to L. agrestis of Europe’, but differed in some anatomical characters. Its distribution was initially listed as New Zealand only (Hutton 1879: 331, 1880: 25), but it was subsequently treated as a junior synonym of Limax agrestis Linnaeus, 1758 (Hutton 1882 h: 154; Hutton 1884 c: 212; Musson 1891: 891; Suter 1892 b: 279; Cockerell & Collinge 1893: 175, 201; Hedley & Suter, 1893: 665; Suter 1913: 1071) and Limax laevis Müller, 1774 (Grimpe & Hoffmann 1925: 408). Barker (1979: 427) inferred that early records of L. agrestis from New Zealand were misidentifications of Deroceras reticulatum (Müller, 1774). He listed L. molestus as a junior synonym of the latter taxon, noting that ‘ Hutton’s brief description appears to fall within the general description of this species’, albeit without examination of type material. Deroceras reticulatum is native to Europe, and has a wide adventive distribution including in central Asia, North and South America, South Africa, islands of the Atlantic and Indian oceans, Australia, New Zealand and some Pacific islands (Barker 1999: 39; Wiktor 2000: 509; Herbert 2010; Welter-Schultes, 2012: 469).

A specimen of A. incommodus that was mentioned by Cockerell (1891 b: 221) as being “ in the British Museum from Dunedin (Otago Univ. Mus.) ” is possibly a syntype (NHMUK 1886.11.18.25). It was evidently sent to London as an exhibit in the Colonial and Indian Exhibition of 1886 and was subsequently purchased by the British Museum. Barker (1979: 418, 1999: 47) was apparently unaware of the type material of A. incommodus in OMNZ and referred to the NHMUK material as a “ type specimen (?) ”, and a “ probable holotype ”, respectively. There has been confusion over the identity of Arion incommodus. Its distribution was initially listed as New Zealand only (Hutton 1879: 331, 1880: 26), but it was subsequently treated as a junior synonym of the European species Arion fuscus (Müller, 1774) (e. g., Hutton 1882 h: 154, 1884 c: 212; Simroth 1889: 65; Musson 1891: 890) and Arion subfuscus (Draparnaud, 1805) (e. g., Cockerell 1891 b: 221; Suter 1892 b: 280, 1913: 1072; Cockerell & Collinge 1893: 190, Hedley & Suter 1893: 665; Thomson 1922: 263). Barker (1979: 418, 1999: 45, 47) examined the specimen of A. incommodus at NHMUK and noted that it appeared to be a junior synonym of Arion hortensis Férussac, 1819. Hutton’s (1879) description was the first record of this taxon from New Zealand. Barker (1982: 178, 1999: 46, 47, map 5) noted that A. hortensis was present in a wide range of modified habitats throughout the North and South islands but was less common in the southern South Island. Arion hortensis is native to northwestern Europe, and has been introduced to New Zealand, Australia, South Africa, North America, Madeira, St Helena and Sri Lanka (Winter 1984: 9; Barker 1999: 46; Herbert 2010; Welter-Schultes, 2012: 476).

The original label of the type material of Milax emarginatus at OMNZ has been lost or destroyed, but transcribed details indicate that this material was collected and identified by Hutton himself (see also Hutton 1884 c: 205). A specimen of M. emarginatus that was mentioned by Cockerell (1891 a: 340) as having been “ found at Dunedin (Otago University Museum), in the British Museum ” is possibly a syntype (NHMUK 1886.11.18.16). It was evidently sent to London as an exhibit in the Colonial and Indian Exhibition of 1886 and was subsequently purchased by the British Museum. There has been confusion over the identity of Milax emarginatus Hutton. Its distribution was initially listed as New Zealand only (Hutton 1879: 331, 1880: 26, 1884 c: 205; Cockerell 1891 a: 340), but Musson (1891: 886) implied that it could be adventive in New Zealand, and Hedley & Suter (1893: 665) listed it as adventive. Suter (1913: 1072) noted that it was related to Limax gagates Draparnaud, 1805, and it was treated as a junior synonym of this species by Thomson (1922: 261), Powell (1979: 450) and Barker (1979: 420, 1982: 178, 1999: 87). Milax gagates (Draparnaud) is thought to be native to the coastal zone and islands of the western Mediterranean, and possibly Canary Islands, and has a very wide synanthropic distribution that includes central and northern Europe, South Africa, Atlantic islands, North and South America, Japan, Australia, New Zealand, and some Pacific islands (Wiktor 1987: 205, map 3; Barker 1999; Herbert 2010; Welter-Schultes, 2012: 432). It was first recorded in New Zealand in the Bay of Islands in 1840 (as Limax fuliginosus Gould, 1852), and was recorded by Barker (1999: 89, map 18) as being widely distributed in modified habitats in the North and South islands, and present also on Chatham Island.

AD3987E6FA04FFE650B6FBDDFE67BCF6.taxon	discussion	Remarks. Hutton (1882 h: 152, pl. 3, fig. E, pl. 4, fig. M) described and illustrated the radula of a semi-slug, that had been “ collected by Mr. T. Kirk, at Waiuku, in the Lower Waikato district ”. He identified this specimen as Daudebardia novoseelandica Pfeiffer [= Rhytididae], albeit noting that its distinctive barbed teeth “ appear to belong to Testacella ”. Hutton subsequently received additional specimens from Thomas Cheeseman that had been collected from gardens in the vicinity of Auckland and decided that they belonged to a new species of Testacella. He submitted a description of Testacella vagans to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883 d: 140), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882 p: 282). A shell from the type series (lectotype) of T. vagans is illustrated here for the first time in pl. 6 fig. G. Cheeseman (1887: 170) suggested that vagans may “ prove to be the European H. maugei, and that it is only naturalised in New Zealand ”. Musson (1891: 885) and Suter (1892 b: 279) also considered that T. vagans was adventive in New Zealand, and it was listed as a junior synonym of T. maugei Férussac, 1819 by Hedley & Suter (1893: 665), Suter (1913: 1073), Thomson (1922: 259), and as a junior synonym of T. haliotidea Draparnaud, 1801 by Barker (1979: 414, 1982: 177). Barker (1999: 98) later concluded that T. vagans was conspecific with T. maugei, based on examination of type material. The latter species is thought to be native to the Atlantic coastal zone between Morocco and NW France, and Canary, Azores, Madeira and Channel Islands (Welter-Schultes 2012: 419), and has been introduced to South Africa and New Zealand (Barker 1999, Herbert 2010). Hutton’s (1882 h, p) descriptions are the earliest record of T. maugei from New Zealand. At present the only confirmed records are from the Auckland region, where this species is still extant locally in modified urban habitats (F. Brook pers. obs.). According to Barker (1999: 99), records of Testacella from elsewhere in New Zealand were based on T. haliotidea Draparnaud. Current taxonomy.

AD3987E6FA05FFE950B6FC69FD13BFEB.taxon	discussion	Remarks. Type material of Cyclotus charmian is illustrated here for the first time in pl. 7 fig. A. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 183), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 477). These descriptions were based on one or more specimens that T. W. Kirk sent to Hutton, and which putatively had been collected at Horokiwi, west of Petone, Wellington. However, there have been no other records of this species from New Zealand, and the locality details given by Kirk were undoubtedly incorrect. Kobelt & Möllendorff (1898: 155) and Suter (1913: 684) considered that Cyclotus charmian was a mislocalised specimen of Cyclostoma (Cyclotus) macgillivrayi Pfeiffer, 1855. The latter taxon, which was described from material in Hugh Cuming’s collection obtained by John MacGillivray in ‘ Aneiteum, New Hebrides’ [= Aneityum, Vanuatu] (Pfeiffer 1855: 104, see also Brazier 1871: 587), was treated as a subspecies of Cyclostoma (Cyclophorus) fornicatum Pfeiffer, 1854, by Sykes (1902: 199), Clench (1949: 20), and as a subjective junior synonym of Gonatorhaphe fornicata (Pfeiffer, 1854) by Solem (1959: 183). The latter species was described from material in H. Cuming’s collection from ‘ New Hebrides’ (Pfeiffer 1854 a: 146). Cyclostoma (Cyclotus) recluzianum Pfeiffer, 1854, the type species of Gonatorhaphe Möllendorff, 1898 by subsequent designation of Möllendorff, 1900, was listed as a subjective junior synonym of fornicata by Sykes (1902: 199), Clench (1949: 19) and Solem (1959: 183). Type material of recluzianum in H. Cuming’s collection was incorrectly listed as being from ‘ Salomon’s Islands’ by Pfeiffer (1854 b: 51), but was actually from ‘ Erromanga, New Hebrides’, according to Brazier (1871: 587). Primary type material of fornicata, macgillivrayi and recluzianum in the NHMUK collection (ex H. Cuming’s collection) was illustrated by Solem (1959: pl. 9, figs. 4 – 6). Gonatorhaphe fornicata (Pfeiffer, 1854) sensu Solem (1959) has a distribution restricted to Vanuatu, and has been recorded from Aneityum, Efate, Erromango and Espiritu Santo (Solem 1959).

AD3987E6FA0AFFE950B6FE1CFDF3B93A.taxon	discussion	Remarks. Type material of Trochomorpha hermia is illustrated here for the first time in pl. 7 fig. D. Hutton submitted a description of Trochomorpha (?) hermia to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 183), and was pre-empted by a brief description of Trachomorpha [sic] (?) hermia in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 477). These descriptions were based on specimens that T. W. Kirk sent to Hutton, and which reportedly had been collected in Manawatu, north of Wellington. Suter (1892 c: 282) noted that hermia “ corresponds quite well ” with Helix (Helicigona) inversicolor Férussac [family Helicarionidae], from Mauritius, and inferred that the type material was mislocalised, and not from New Zealand. Suter (1913: 684) stated that hermia is not a New Zealand species, and treated it as a synonym of Pachystyla inversicolor (Férussac, 1821), as did Freeman et al. (1997: 32), but this name is a nomen nudum, as pointed out by Kennard (1943: 123), and the currently recognised name of the Mauritian taxon is Pachystyla bicolor (Lamarck, 1822) (e. g., Griffiths & Florens 2006: 127 – 128, pl. 32. figs. C – F). Subadult shells of P. bicolor are similar to Trochomorpha hermia, but the two taxa have very different teleoconch microsculpture, and are not conspecific (Owen Griffiths pers. comm. 2019). During the present study Michael Shea and Isabel Hyman (pers. comm. 2019) pointed out that, rather than being from Mauritius, Trochomorpha hermia is in fact conspecific with Helix campbellii Gray, 1834, which is endemic to Norfolk and Philip islands, Australia. The latter is the type species of Advena Gude, 1913, and belongs in Microcystinae Thiele, 1931 (Isabel Hyman unpub. data). Advena campbelli was described from material collected on Philip Island (Gray 1834: 65); a syntype (NHMUK 1982239) is illustrated here for the first time in pl. 7, fig. E.

Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884 b: 180), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883 g: 476). These descriptions were based on specimens that T. W. Kirk sent to Hutton, and which putatively had been collected at Palmerston North, north of Wellington. However, there have been no other records of this species from New Zealand, and the locality details given by Kirk were undoubtedly incorrect. Suter (1913: 683) considered that Amphidoxa lavinia Hutton, 1883 was a junior synonym of Helix capillacea Férussac, 1832, from Australia, as did Iredale (1938: 119). Smith (1992: 299) stated that A. lavinia was “ not known to occur in Australia ”, but this was probably based on a misinterpretation of Iredale’s synonymy. Re-examination of type material indicates that Amphidoxa lavinia Hutton, 1883 is actually a synonym of Helix sinclairi Pfeiffer, 1846. The latter taxon was described from one or more specimens collected by Dr. Andrew Sinclair in ‘ Van Diemensland’ (= Tasmania, Australia). The lectotype (NHMUK 1842.11.2.23), fixed by inference of holotype (ICZN Article. 74.6) by Smith (1992: 304), is illustrated here for the first time in pl. 7, fig. C.
