S. femoralis is a uniformly brownish-black monkey, the limbs, head, and tail 

 being almost wholly black, but the difference between the colours is not well defined, 

 and the fore-limb is grizzled with whitish hairs. The tail is slightly tufted at its 

 extremity. There is a rather short, vertical crest directed backwards, the hair 

 anterior to it projecting forwards over the eyebrows. The ears are moderately 

 large and partially exposed. The hair on the front and side of the head and on the 

 middle of the crest is blackish or dull brown. The upper lip and chin are clad 

 with short whitish hairs, with longer black hairs intermixed on the chin. Along the 

 flanks the hair is short, sparse, brown, and somewhat grizzled, which is the character 

 also on the belly. The throat, sides of the neck and chest are concolorous with 

 the upper parts. A narrow, well-defined white line passes along the middle 

 of the under surface from the chest in the adult to the hinder portion of the 

 abdomen, but in young specimens this line is obscure, as the throat, chest and 

 abdomen are yellowish white, and where it dies away on the inside of the limb, 

 the white line is prolonged as a fine line to the wrist and ankle. In the adult 

 the brachium is greyish, but there is a distinct tendency visible to the formation of 

 a narrow obscure greyish line along the inner aspect of the antibrachium, but 

 of variable intensity. Between and inside of the thighs is also white or pale grey, 

 and this colour extends a short way below the knee. The face, ears, and the palms 

 of the hands and sides of the feet black.^

Inhabits Borneo and Sumatra. 



As has been pointed out by previous authors, there do not appear to be any 

 facts relating to the structure of the so-called S. chrysomelas from Borneo that 

 would sanction its recognition as a species distinct from S. femoralis of Sumatra, 

 and I have arrived at this opinion after an examination of the type specimens. 

 Miiller and Schlegel described as a female of this species a monkey of a yellowish 

 colour, but which must have been originally much brighter, seeing it had been 



' Miiller and Sclilegel have represented the face of S. chrysomelas as bluish, but they state that it is quite 

 hypothetical, as the colour of the face of this Bornean monkey in life is not known.
