Diar/nosis. — Allied to Pteropus, but i^ about twelve to fifteen 

 times tlie bulk of i,, upper canines excessively heavy, with large 

 posterior secondary cusp, upper molarilorm teeth subsquarish with 

 prominent anterior and posterior basal ledges, and external main 

 cusp of p,, nij, and m^ bitid. Wings from spinal line : ears broadly 

 rounded off above. Size (two species known) as an average 

 Pteropus; forearm about 140 mm. Apparently confined to the 

 Solomon Islands. 



Skull (tig. 21). — Essentially Pleropine, most closely approaching 

 the skull of typical species of the Fteropius pselapJion and .samoen.sis 

 groups {ef. fig. 15, p. 302. Pt. psclaphon, and fig. 14, p. 289, Pt. ane- 

 tianus). llostrum short and very broad, not conspicuously tapering 

 anteriorly, lateral margins subparallel ; length of rostrum, from front 

 of orbit to tip of nasals (17'2-19 mm.), contained nearly four times 

 in total length of skull (66-5-70-2 mm.), and subecjual to breadth 

 . across external surfaces of upper canines (17-2-1 7'5); front of 

 • orbit vertically above middle or posterior half of p'. Inter- 

 premaxillary suture distinct in young, obsolete in aged individuals. 

 Maxillary tooth-rows subparallel; palate Pteropine, except for its
