GENUS PTILINOPUS SWAINSON, 1825

Remarks: Material was referred to Ptilinopus by general similarity of form and size to compared specimens of Ptilinopus and especially to Ptilinopus regina Swainson, 1825 SAM B 37060, NMV B16328, including the following features from Worthy et al. (2015): coracoid (terminology after Worthy, 2012) tuberculum A separated by a distinct groove from and less dorsally protuberant than ilaa; ilaa offset cranially from ilap, meaning that in medial view, the facies articularis clavicularis is longer craniosternally than dorsoventrally wide; ilaa and ilap linked by a slightly arched crest lacking a noticeable notch; pneumatic foramina present under facies articularis clavicularis; and processus procoracoideus short. In the Tongan region, two Ptilinopus species are found, the smaller Ptilinopus perousii Peale, 1849 and larger Ptilinopus porphyraceus ( Temminck, 1821) (see Worthy & Anderson, 2009; Dickinson & Remsen, 2013). Skeletal material of Pt. perousii was not available to us, but the following material was all of a size similar to that of Pt. regina SAM B 37060 and NMV B16328 and rather smaller than Pt. porphyraceus , e.g. MNZ O.16391 (see Goodwin, 1967).

PTILINOPUS SP. MAGN. PT. PEROUSII PEALE, 1849 , MANY-COLOURED FRUIT-DOVE

Material: Hopoate: NISP = 9, MNI = 2. Nukuleka: NISP = 2, MNI = 1.

COLUMBID SP. INDET . SMALL PIGEON

Material: Hopoate: NISP = 5, MNI = 1. Vuna: NISP = 1, MNI = 1.

Remarks: These specimens are too fragmentary for certain generic referral and are unlikely to increase the MNI for small taxa ( Alopecoenas and Ptilinopus ) known at the generic level.

COLUMBID SP. INDET . LARGE PIGEON

Material: Hopoate: NISP = 2, MNI = 1. Nukuleka: NISP = 6, MNI = 3. Falevai: NISP = 2, MNI = 1. Ofu: NISP = 2, MNI = 1. Otea: NISP = 1, MNI = 1. Vuna: NISP = 7, MNI = 1.

Remarks: These specimens are too fragmentary for certain generic referral and are unlikely to increase the MNI for taxa known at the generic level.
