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

 the maxillary and nasal bones, and in having nearly all its processes and 

 I'idges much more strongly defined. The distance between the small ante- 

 rior upper premolars exceeds that in Pt. medius by one-tenth of an inch. 

 T\iQ foramen ovale is divided in the centre by a process of bone, in Ft. 

 tnedius it is undivided. A post-orbital process of the zygomatic arch is pre- 

 sent, though not so well developed 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 margin is nearly 

 straight, not deeply concave, and its superior angle is narrowly, not broadly 

 rounded off as in the latter species. 



The teeth are stouter in Pt. nicoharicus but their general characters 

 are the same in both species.'* 



Hah. — Andaman and Nicobar Islands, probably Java also. An old 

 dried specimen in the Indian Museum is labelled Java, but not numbered 

 in Blyth's Catalogue. 



Neither Fitzinger nor Blyth described this species, though they invent- 

 ed names for it. Zelebor's description occupies nearly two pages of a quarto 

 book, and very careful measurements of the original specimen are given, yet, 

 as his description is taken from a young individual and contains few really 

 diagnostic characters, I was unable to feel certain that specimens obtained 

 by me last year from the Andamans and Nicobars should be referred to this 

 species. But Dr. Peters has lately, at my request, very kindly compared some 

 specimens sent to him from the Indian Museum with the type specimens of 

 Pt. nicoharicus in the Vienna Museum. He informs me that they agree in 

 the form of the ear and feet. With this additional information I feel no 

 hesitation in referring the specimen from which the above description is 

 taken, to that species.
