106 RHINOPITHECUS 



covered with short silver white hairs. Hands, feet, and fore parts of 

 head missing. Ex type British Museum. 



Measurements. Total length, 1,740; tail, 1,050, (skin). No skull. 



A young animal, sex unknown, from the same mountain range is 

 also in the British Museum. It is complete and resembles the adult. 

 Forehead and top of head white, with long stiff black hairs on the 

 superciliary line; space about eyes orange? perhaps flesh color; nose 

 black, rest of face covered with short white hairs ; whiskers reaching 

 ears, whitish, but changing to black over temples ; back of neck brown- 

 ish and black mixed, running into the white patch between shoulders ; 

 upper parts of arms brownish gray; outer side of arms blackish 

 brown becoming black on the hands ; outer side of legs grayish white, 

 with a black line from hip over knee nearly to ankle; under parts, 

 and inner side of limbs grayish white, becoming smoky gray on legs 

 below knees; tail blackish brown, with white speckling mostly notice- 

 able at base ; ear tufts white. 



This specimen is interesting on account of giving us some idea 

 of the color of the face, hands and feet, which in the adult would 

 probably be black, but instead of the white head the same coloring 

 seen on the anterior portion of the head of the adult would probably 

 be continued to the forehead. As the measurements show, this is 

 a very large monkey, with an extraordinarily long tail. In its style 

 of coloring and texture of hair it differs much from R. roxellan^, 

 and it will be interesting to obtain an adult skull to learn if this species 

 is really a third member of Rhinopithecus or represents another 

 genus. 



It evidently is a dweller of high mountains, the young one having 

 been shot by a native hunter at an altitude of 7,000 to 8,000 feet. The 

 two skins are the only ones yet obtained and nothing whatever is 

 known of the creature's habits.
