 prominently black, and their nearly naked surfaces with minute 

 black lines. Hands and feet blackish, lighter along their inner edges 

 terminally. Tail very thick and bushy ; its wool-hairs buft'y, its 

 long hairs glossy blackish. 



Skull considerably smaller than that of alboniger; postorbital 

 processes less developed. Palate unusually arched between molars, 

 its posterior median projection strongly developed.
