03CE8790FF83FFD9FF47FE73261C2CFA.taxon	discussion	REMARKS The shell of Murex protocrassus is similar to those of the various subspecies of M. brevispina (M. brevispina brevispina Lamarck, 1822, M. brevispina macgillivrayi Dohrn, 1862, M. brevispina senilis Jousseaume, 1874, and M. brevispina ornamentalis Ponder & Vokes, 1988) but differs from them in its more numerous axial ridges on the early teleoconch whorls and in its more spinose siphonal canal. Other differences are its large and broad protoconch, which indicates intracapsular larval development, and the absence of a labral tooth. Due to the lack of the labral tooth it cannot be classified in Murex s. s. It is therefore included in Promurex as in Merle et al. (2011). The French fossil Murex spinicosta Bronn, 1831 (Fig. 4 C), another species without a labral tooth, was classified in Promurex by Ponder & Vokes (1988: 15), and was illustrated by Landau et al. (2007).	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF83FFD8FD06FDF127FB2EF1.taxon	discussion	REMARKS There are 14 species of Pygmaepterys in the tropical Indo-West Pacific. Three of them have only three axial varices on the last teleoconch whorl, two other species are very small and are geographically restricted to South Africa, while another three species live in the vicinity of the Gulf of Aden and Oman. These eight species do not need to be discussed further here because of their very different shell morphology. Favartia funafutiensis (Hedley, 1899) has a different protoconch morphology, in that it is conical with 2 + whorls, and weakly and narrowly keeled abapically. The five remaining species are F. avatea Houart & Tröndlé, 2008, F. bellini (D’Attilio & Myers, 1985), F. isabelae Houart & Rosado, 2008, F. kurodai Nakamigawa & Habe, 1961 and F. philcloveri (Houart, 1984). Favartia lifouensis n. sp. differs from F. avatea (Fig. 1 E, F) in having a more strongly shouldered shell with a more weakly sloping subsutural area, a higher and narrower spire, a comparatively broader protoconch, an adpressed suture instead of the impressed one in F. avatea, fewer axial varices, 5 on the last whorl and 6 or 7 on previous whorls in P. lifouensis vs 6 on the last whorl and 7 - 9 on previous whorls in F. avatea, and weaker, more numerous apertural denticles. It differs from F. bellini (Fig. 1 G, H) in having a less shouldered and more ovate shell, narrower, more conspicuous and higher spiral cords and a comparatively broader aperture with smaller denticles. Favartia isabelae, F. kurodai and F. philcloveri also differ in many ways, including shell height and width, and protoconch, spiral sculpture and aperture morphology.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF87FFDCFCF2FDD120D02E30.taxon	discussion	REMARKS There are six known Recent species of Pazinotus in the tropical Indo-West Pacific: P. brevisplendoris (Houart, 1985), P. falcatiformis (Thiele, 1925), P. kilburni (Houart, 1987), P. sibogae (Schepman, 1911), P. smithi (Schepman, 1911) and P. spectabilis Houart, 1991. None of these is particularly close to P. chionodes n. sp. except P. falcatiformis (Fig. 2 K, L), which differs from P. chionodes n. sp. in having a more triangular outline, a less expanded varical flange, 5 lamellate varices on the last teleoconch whorl, and in having a comparatively narrower aperture.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF88FFD1FCCEFA4E27882E91.taxon	discussion	REMARKS The genus Gemixystus was revised by Houart (2004) and contains six fossil and eight Recent species. None of the fossil species is closely related to the new species and of the eight Recent species, only three need to be compared here: Gemixystus leptos (Houart, 1995) from southern Queensland, Australia, to the Chesterfield Reefs, Gemixystus rippingalei (Houart, 1998) from Queensland, Australia, and Gemixystus stimuleus (Hedley, 1907), from southern Queensland and Sydney, New South Wales, Australia, type species of Apixystus. Gemixystus calcareus n. sp. differs from the quite similar G. stimuleus (Fig. 2 E) in having a comparatively larger shell with twice as large a protoconch, more numerous axial lamellae, 20 vs 11 or 12 on last whorl and 16 vs 13 - 15 on penultimate whorl. The spiral sculpture also differs, G. calcareus n. sp. having P 1 - P 5, ADP and MP on last teleoconch whorl vs P 1 - P 3 in G. stimuleus, which has no spiral sculpture on the siphonal canal.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF88FFD1FCCEFA4E27882E91.taxon	description	Gemixystus calcareus n. sp. also differs from G. rippingalei (Fig. 2 F) in having a comparatively larger shell, G. rippingalei reaching only 4.4 mm in height and having a longer siphonal canal, a less spiny shell and a different spiral sculpture morphology, that is, a last whorl with closely spaced P 1 - P 4 and a smooth siphonal canal. Finally, G. calcareus n. sp. differs from G. leptos (Fig. 2 G) in having a comparatively broader, but otherwise similar protoconch, a less shouldered and less spiny shell with more numerous axial lamellae, 20 vs 10 or 11 on 4 th whorl and 16 vs 11 on penultimate whorl, while having fewer lamellae on first whorl, 8 vs 10 or 11 in G. leptos. The spiral sculpture morphology also differs, G. leptos having two broad, broadly spaced P 1 and P 2 and two small, narrow, closely spaced P 3 and P 4. The siphonal canal is smooth in G. leptos or with a very shallow and narrow MP only.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF8AFFD6FF3AFCF4279A2836.taxon	discussion	REMARKS The genus Leptotrophon currently includes 28 Recent species, a majority of them (25) described from New Caledonia and neighbouring localities. One species was described from Indonesia, and another from Brazil. Leptotrophon segmentatus (Verco, 1909) (Fig. 3 G, H) from South Australia is here included for the first time in Leptotrophon, based on shell morphology. Leptotrophon wareni n. sp. can be usefully compared with only three species: L. segmentatus, L. coralensis Houart, 1995 and L. minispinosus Houart, 1995. All other species differ in many distinct ways.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.

03CE8790FF8AFFD6FF3AFCF4279A2836.taxon	description	Leptotrophon wareni n. sp. differs from L. segmentatus in having a narrower shell with a less acute spire, more widely spaced and lower spiral cords, more numerous and narrower spiral cords on the siphonal canal, and an aperture with adherent inner lip, contrasting with the widely flaring lip of L. segmentatus. It differs from L. coralensis (Fig. 3 I, J) and L. minispinosus (Fig. 3 E, F), two species also with very high spires, in having a more nodose, less shouldered shell, broader axial varices, and in having more numerous visible spiral cords on early teleoconch whorls, L. coralensis and L. minispinosus having only one visible spiral cord (P 1) from 1 st to 4 th teleoconch whorls in adult specimens, while the subsutural ramp in these species is also broader and more strongly sloping.

REMARKS This is the first record of Leptotrophon coralensis since its description and the second known specimen. It seems to be one of the rarest species of Leptotrophon from New Caledonia. The coordinates and depth are quite similar to those of the original material, which was also collected in the Coral Sea, Chesterfield Reefs at 21 ° 01 ’ S, 160 ° 57 ’ E, in 650 - 660 m. The holotype and this additional specimen were both dead collected. The additional specimen closely matches the original description but due to its broken siphonal canal is not as high as the holotype, the height of which is 9.5 mm.	en	Houart, Roland, Héros, Virginie (2012): New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.
