This species resembles Pt. nicobaricus in the colour of the fur and 

 in size, but the differently shaped ears and much larger premolars 

 and molars at once distinguish it.

Ears about as long as the muzzle, obtusely pointed, rather broad, 

 in some specimens triangularly rounded off above ; the inner and 

 outer sides of the basal half of the concave surface of the conch 

 with a tuft of rather long hairs ; interfemoral membrane short, 

 about 0"-3 deep in the centre, concealed by the fur behind; wings 

 nearly one inch apart at their origin from the sides of the back. 



The colour of the fur appears to vary considerably. In an 

 apparently adult female the face and crown of the head are silvery 

 grey, with some intermixed dark hairs ; sides of the face and under 

 surface of the muzzle reddish brown and grey mixed ; back of the 

 head, neck above and beneath, and shoulders yellowish ; chest and 

 abdomen yellowish buff, sides of the body beneath the wings reddish 

 brown. Fur of the back very short, black-brown, with shining 

 extremities, slightly reddish brown on rump. This is the general 

 colour of specimens from Ternate. 



A younger individual from Banda has the head and neck brownish 

 yellow, the head darker than the neck and with a greyish tinge, 

 shoulders passing into yellowish buff ; back greyish brown ; chest 

 and abdomen yellowish brown, paler in front and behind; fur 

 extending upon half the inner sides of the tibiae. 



A nearly adult male from Dinagat Island, S.E. Philippines, in the 

 collection, has the face yellowish brown, with intermixed black 

 hairs ; the crown of the head bright yellowish buff ; the collar 

 ferruginous red ; the shoulders as the crown of the head ; the 

 throat black, the breast and abdomen as the shoulders ; the sides of 

 the body and thighs dark brown, back similar, paler behind ; hairs 

 of the back rather long, scarcely appressed ; the greater part of the 

 interfemoral clothed with long fur, which extends upon the inside 

 of the tibise halfway to the ankles. 



In most specimens the forearms and legs axe almost naked, and 

 the wing-membrane beneath is clothed with rather short fur between 

 -the humerus and femur and along the forearm.
