The general colour of this species is uniform greyish black, becoming black on 

 the hands and feet ; the lower part of the back, the base of the tail, and the outside 

 of the upper part of the thighs are grey, tinged with brown in younger specimens, 

 and the hair is rather short. The tail is tufted, becoming albescent towards its tip. 

 The top of the head and the back of the neck are greyish brown ; strong, black, 

 supraorbital hairs extending outwards to near the ear. A ruff of white hairs, more 

 or less tinged with brown, encircling the face and extending on to the throat and 

 under surface of neck ; the hairs on the sides of the face long, soft, and pointed up- 

 wards, forming a conspicuous whisker. The skin of the face black, with a purplish 

 tinge ; the palms and soles dull black. The under parts are dusky grey or only 

 paler than the back, but generally the insides of the thighs anterior to the callosities 

 are pale yellowish, almost white. 



Length of body 1 foot 9 inches, and tail 2 feet 7 inches. 



Habitat. — Ceylon, but to no great altitude. 



The young of S. cepMlopterus generally resembles the parents, but I have 

 before me a young female from Ceylon, uniform pale yellowish, the top of the head 

 being faintly washed with brownish and the shoulder and the middle of the back 

 tinged with dusky. There can be no doubt of the identity of the race or variety 

 with S. cephalopterus} 



The characters of the skull and wherein they differ from S. ursinus, the most 

 nearly allied form, will be found stated under that species. 



I have examined the type of Desmarest's S. leucoprymnus in the Paris Museum, 

 which exactly agrees with the foregoing description, but I cannot say as much for 

 the type of S. latibarbatus, which is quite a baby ; it is wholly yellow, with paler 

 cheeks and chin, but the locality from whence it came was unknown. In the Cat. 

 Method, des Mammiferes this monkey has still been retained as distinct from ^S*. 

 cephalopterus, and it is there remarked that the individual is unfortunately very youns^, 

 but that the examination of it and Pennant's figure furnishes many arguments in
