woolly; above, it grows thinly along the humerus and half the 
forearm, and thickly over the whole of the interfemoral membrane, 
and down the tibiee 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 Pt. pheocephalus. 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.
