436 Monograph of the Genus Semnopithecus. 



The chingkau when very young is of a reddish fawn colour, with black- 

 ish hands and feet ; when half grown of a. greyish brown, with black hands 

 and feet, the frontal hairs diverging forward, and the peaked crest being 

 distended. 



The contour of body remarkably slender. Length nearly 2 feet ; tail 2 

 feet 6 inches. 



This species is certainly not identical with the Simia 

 Maura of Schreber, as Fischer intimates, but with the Sem- 

 nopithecus pruinosus of Desmarest. 



Habitat Sumatra, Java, &c.

S. Maurus. 



We cannot but consider the Simia Maura of Schreber as distinct from 

 the S. cristata of Raffles, (the Semnopithecus pruinosus of Desm.); and we 

 have had the opportunity of examining a young individual, which we hesi- 

 tate not to regard as this species, and which closely agrees with the " mid- 

 dle-sized black monkey" of Edwards, vol. vii. plate 311. The specimen in 

 question was brought from India, but the exact locality could not be dis- 

 tinctly ascertained. The hair on the head is full, but does not rise into a 

 crest ; that on the forehead is directed forwards from a central point at the 

 top of the frontal bone : the hair on the sides of the face is long and bushy, 

 obscuring the ears : the fur is full and rather soft. Colour glossy black; a 

 grey indefinite mark underneath the root of the tail ; the thinly scattered 

 hairs between the thighs, white. 



Length 18 inches ; tail 22^ inches. 



That this is not S. cristata, in an intermediate stage, is ve- 

 ry plain, not only because there is no peaked crest on the 

 vertex, but because, in the middle age, this latter species is 

 dull greyish brown, with black hands and feet : neither is the 

 ridge of the nose between the orbits elevated, as in a young 

 S. cristata of the same size.
