1882.] FROM THE CAROLINE ISLANDS. 757 



woolly ; above, it grows thinly along the humerus and half the 

 forearm, and thickly over the whole of the interfemoral membrane, 

 and down the tibiae nearly to the ankles. Beneath, the proximal 

 halves of the humeri are covered ; there are a few hairs behind the 

 elbow and on the proximal third of the interfemoral. The fur along 

 the back is nearly two inches in breadth. 



Ears very short and almost buried in the fur, both edges evenly 

 convex, the outer more strongly so than the inner ; tip sharply 

 pointed. Wings arising within half an inch of each other on the 

 back. Interfemoral membrane very narrow in the centre, quite 

 hidden by the fur. 



Teeth (Plate LV.) smaller even than in Ft. phceocephalus. Ca- 

 nines with much narrower postero-internal ledges. Above, the 

 first premolar is either absent, or, if present, stands quite outside 

 the tooth-row ; last molar about the same size as one of the outer 

 incisors. Below, the first premolar is slightly larger than the penul- 

 timate molar, the latter, like the other molars, being remarkably 

 small. Last molar about equal to one of the outer incisors. 



The following are the dimensions of three specimens of this species. 

 The first is the specimen described ; the other two, however, only 

 differ from it in being of a somewhat darker colour throughout 

 and in having slightly longer ears.

This species may be readily recognized by its small size, short 

 head, and remarkably small rounded molars, in which latter cha- 

 racter it by far exceeds any other Pteropus known, with the excep- 

 tion of P^. scapulatus, Ptrs., an otherwise wholly different form.
