tint of yellowish brown. The rump and the base of the tail, which, even occasion- 

 ally in the young, but generally in the adult, are grey. 



The tail is about one-sixth longer than the body. 



Length of body to root of tail 26 inches, length of tail 30 inches. 



The skull of S. johnii is about the same size as that of S. cephalopterus, 

 to which it is closely aflSined, but the muzzle is considerably narrower and somewhat 

 shorter, and the interval between the eyes is not so broad. Owing to the narrow 

 muzzle, the palate is more contracted than in either S. cephalopterus or S. ursinus, but 

 the teeth are somewhat larger. The supraorbital ridges are but little developed, and 

 the breadth across the fronto- malar suture is about the same as in S. cephalopterus, 

 also the breadth of the skull. The symphysis of the lower jaw is much shorter 

 than in >S'. cephalopterus, but the distance between the angles of the jaw is much 

 greater than in that species, and the dental ramus is not nearly so deep, nor is 

 the transverse breadth of the ascending ramus so great. 



It inhabits the high country from the Nilgiris to Travancore. 



Its nearest allies are the white-whiskered S. cephalopterus of Ceylon, and 

 Semnopithecus obscurus on the eastern side of the Bay of Bengal. 



>S'. johnii is usually found in small troops, and leaps with amazing agility and 

 has a loud call like S. entellus. 



Mtiller and Schlegel regarded S. johnii as simply a climatic race of S, cephalop- 

 terus, an opinion which was at one time held by Blyth, but with other limitations.
