breast and belly. - Mantle ocliraceous-buff, lighteninf^ to buffy or 

 crcam-bufty posteriorly ; occiput and sides of neck similar to 

 mantle, but rather more tinged with ochraceons ; I'lir of foreneck 

 ochraceous at base, seal-brown at tip, making colour of foreneck 

 superficially like that of breast. — Forehead, crown as far back as 

 front of ears,, sides of head, chin, and throat seal-brown. 



Cotype A. 57 (J ad.) is in poor condition, but has apparently 

 not differed in any noteworthy respect from foregoing. 



Measurements. On pp. liJO, 191. 



Sjjecmens examined. Four, in the collection of the Paris Museum, 

 including the two cotypes of the species and one cotype of 

 Ft. rlussumieri. 



Range. The island of Vanikoro. 



Cotypes in the Paris Museum. 



Pteropvs duss%(mierl,ls. (jQo^ve^y ; 1828. — Based on two speci- 

 mens, the one stated to have been brought by Dussumier from the 

 continent of India, the other supposed to be from Araboina. The 

 former is in the Paris Museum (Reg. no. A. 61 ; 2 ad. mounted, 

 skull in situ) ; it has been acquired through Yerreaux and is 

 ticketed "Bengale?": the latter I have not been able to find in 

 the Paris collection, nor iu the manuscript register of Chiroptera of 

 that Museum. Both of the localities given by Is. Geoff'roy are 

 undoubtedly incorrect. The cotype examined by me is externally 

 indistinguishable from Pf. vanikorensis, but the characters of the 

 skull and teeth are in this group of the genus of such decisive 

 importance that the identification of Ft. dussumieri remains 

 uncertain so long as its skull has not been made available for 

 examination. 



Fteropns vanil-orenfiis, Quoy and Gaimard ; 1830. — Original 

 description based on two specimens obtained in Vanikoro during 

 the voyage of the ' Astrolabe ' (Paris Museum, E,eg. nos. A. 57 and 

 A. 58), both males, mounted, skull of A. 58 in situ, of A. 57 

 extracted in 1907 ; cotype A. 58 is probably the original of Quoy 

 and Gaimard's pi. ix. A third mounted specimen in the Paris 

 collection (A. 59, not full-grown), though marked "P. vanilor- 

 eiisis, Q. & G. ; type ; Vanikoro : Quoy & Gaimard, Astrolabe," 

 cannot technicallj' be considered a cotype, since it is not referred 

 to in the original description. — The skull described by Quoy and 

 Gaimard as being that of Ft. vanilcorensis (Paris Museum, no. 6746) 

 belongs to a totally diflerent species, Pt. tuhereidatus, Peters. 



lientarh^. — This species is readily distinguished from Pt. mari- 

 annvs by its lai'ger orbits. From the closely allied Pt. tonganus 

 it differs by its slightlv smaller size (forearm 136-137, against 

 139-150 mm.) and relatively shorter metacarpals (third metacarpal 

 88-5, against 93-5-1 02-5 mm.).
