226 PITHECUS 



The unique type of this very unusually colored Macaque is stated 

 to have come from Cochin China, no particular locality in that country 

 specified. In its peculiar brown and olive yellow speckled fur it 

 resembles somewhat in color the long-tailed species P. irus Cuv., of 

 the Malay Peninsula, Burma, etc., but is a much more powerful animal 

 than that species, has no reddish brown on the head, and a much 

 shorter tail. In fact it does not closely resemble any species of 

 Macaque with which I am acquainted.
