68 PYGATHRIX 



A specimen in the British Museum obtained from the Genoa 

 Museum and procured by Dr. Modigliani in Sipora, Mettawee Islands, 

 answers to the description of 6". potensiani Bon., and is the same as 

 5". chrysogaster Peters. The habitat of the species is therefore fixed. 

 It has also been taken on South Pagi Island of the same group by 

 Dr. Abbott, who sent a series of examples to the United States Na- 

 tional Museum.

While resembling in some respects P. potenziani, it dififers from 

 that species in having the under parts of the body black, no rufous 

 appearing anywhere. Its habitat also, on the borders of Tonkin and 

 China, is far removed from the Mettawee Islands where P. potenziani 

 is found, for there is no proof that that species inhabits Tenasserim or 

 any portion of the continent, being, so far as known, strictly an island 

 species. 



Subgenus Presbypithecus.
