About the size of Pt. medius, which it also resembles closely in 

 the form of the head and body, but is at once distinguished by the 

 much shorter and differently shaped ears. Ear-conch rounded off 

 above, the upper third of its outer margin slightly flattened, not 

 concave, the lower two thirds convex ; in full-grown individuals the 

 greatest diameter of the opening of the external ear, from the point 

 of junction of the outer and inner margins below to the tip of the 

 ear above, scarcely exceeds one inch. 



The distribution of the fur is similar to that of Pt. medius ; but 

 the hair on the wing-membrane is very much shorter. 



In some male specimens the coloxir of the fur also corresponds to 

 a certain extent with that of Pt. medius ; generally, however, the 

 lighter-ooloured portions of fur on the nape of the neck, and on the 

 shoulders and chest, are of a deeper hue than in the latter species, 

 usually dark ferruginous red or chestnut ; females and young males 

 are commonly intensely black throughout ; in some female specimens 

 the position of the light-coloured tippet in the male is indicated by 

 a reddish tinge of the black hair. 



The skull differs from that of Pt. medius in being shorter, 

 wider across the maxillary and nasal bones. The distance between 

 the small anterior upper premolars of opposite sides exceeds that in 

 Pt. medius by one tenth of an inch. The fo7-a7nen ovale is divided 

 in the centre by a process of bone ; in Pt. medius it is undivided. A 

 postorbital process of the zygomatic arch is present, though not so 

 well defined as in Pt. medius. 



The mandible is shorter and its rami deeper than in Pt. medius : 

 the coronoid process is more developed vertically ; its posterior
