The body, generally, covered ■with rather long deep black hair in the adult, 

 which becomes tipped or intermixed with silvery white in the old animal. The under 

 surface of the body is less densely covered than the back, and the abdomen is nearly 

 naked. The hair on the head is either erectly divergent all round the face and over 

 the upper front of the head, or in some it may radiate from a centre, being long and 

 bushy on the sides of the face, becoming directed backwards on the cheeks, and 

 passing under the ears in the form of pointed whiskers. In some animals there is 

 a white spot at the base of the tail beneath, but this character is very variable. The 

 face is black, with a kind of warm tint, and is rather flat. 



Length of body 1 foot 5"50 inches, length of tail 1 foot 11-50 inches. 



The young are uniform reddish brown, but the change from this colour to that 

 of the adult is soon inaugurated and begins first on the extremities of the animal 

 as grey, and afterwards shows itself on the upper surface of the head, on the 

 shoulders and flanks, which become black, this colour rapidly spreading all over the 

 body and last disappearing on the whiskers. 



The form described by Horsfield as S. pyrrhus, and which is associated in Java 

 with S. maurus, appears to be only a variety of the latter species, as its form and
