 N'ostrils projecting ; upper lip with a vertical groove in front, hounded 

 laterally hy naked prominences ; index finger with a distinct claw ; metacar- 

 pal hone of second finger exceeding slightly in length the index finger ; wings

Ears large, rounded at the tip, with a slight but distinct concavity of 

 the outer margin immediately beneath the tip ; both the outer and inner 

 margins are bordered with white ; the white border along the inner margin 

 is about one-twelfth of an inch wide, and contrasts strongly with the dark 

 brown colour of the ear ; the outer margin terminates below without forming 

 a lobe at the base. 



Nostrils projecting, with a deep intervening emargination. The upper 

 lip marked in the centre, as in Pteropus, with a narrow vertical groove 

 bounded laterally hj naked rounded prominences continuous with the integ- 

 ument of the nostrils. 



The ears are naked posteriorly except at their bases ; anteriorly, a few 

 hairs appear on the conch along the outer side of the white border of the 

 inner margin of the ear, and, similarly, along the inner side of the white 

 border of the outer margin. On the upper surface, the fur of the back 

 extends upon the wing-membrane nearly as far as a line joining the elbow 

 and knee joints, also, thinly, upon the humerus, the femur, and proximal end 

 of the tibia. Beneath, the antebrachial membrane is covered with moder- 



* I have placed the genus Cynopterus next Pteropus as I believe it presents more 

 affinities with that genus than any of the other genera of PteropidcB. The species of 

 these genera agree very closely in the form of the nostrils and of the narrow emargi- 

 nation on the upper lip bounded by naked prominences. In Cynonijcteris this emargi- 

 nation is wide and deep with slanting sides, altogether very different from the same 

 part in Pteropus. In habit also the species of Cynopterus and Pteropus perfectly 

 agree j they are all strictly frugivorous bats and live in trees, while the species of 

 Cynonycteris are commonly found in caves, and I have been informed that a colony of 

 C. amplexicaudata living near the sea were seen to feed on Mollusca left exposed 

 by the tide.
