PITHECUS 251 



Islands. Altitude 6,000 feet. Type in United States National Mu- 

 seum. 



Color. "Upper parts yellowish olive, the hairs everywhere annu- 

 lated with blackish; top of head slightly washed with burnt umber; 

 sides of head pale olivaceous gray, separated from the crown by a 

 fringe of strong, stiff black hairs ; face gray ; under parts whitish smoke 

 gray; genitals bistre; outer surface of limbs pale yellowish olive, 

 changing to oh've gray on lower portion, and on hands and feet ; upper

 and smoke gray on under side."

 58; total length, 925; tail, 400; foot, 115." 



This is a female, and in color, with the exception of the hands and 

 feet which are lighter, it is exactly like P. cagayanus, and at present 

 it is impossible to give it any definite status, but it will probably prove 

 to be the same as P. mindanensis = P. philippinensis I. Geoff.
