Monograph of the Genus Semnopithecus. 439 



S. auratus. 



Colour bright glossy golden yellow, washed with rufous about the back, 

 and passing into cinereous on the forearms and outside of the thighs. — 

 Hairs of the head long, but those on the body and limbs are rather short, 

 and inclined to be curly, being very different in character from the long 

 soft falling hairs of S. Pyrrhus, and S. melalophos. 



The length from the neck, (the head being removed), to the insertion of 

 the tail, 18 inches; the tail being 22 inches: allowing 4 inches for the head, 

 the total length of the body would be, as that of the tail, 22 inches. 



The above description is taken from an imperfect skin which 

 we have had an opportunity of examining. 



S. fulvo-griseus ; Demoul. in ' Diet. Class. d'Hist. Nat.' 



General colour fulvous grey, passing into brown on the shoulders and 

 lower part of the four limbs ; the hands and feet black ; the face tan-co- 

 loured ; the moustaches, throat, and chin of a dull greyish white. The tail 

 consists of 32 vertebral bones, and is one fourth longer than the body, of 

 which the trunk is shortened, as in the lotong, by there being fewer lumbar 

 vertebra, namely 5. The fingers are very long and very slender, and their 

 phalanges are well arched ; the upper canines are very large, and furrowed 

 anteriorly. 



M. Diard found this monkey at Java. Vide 'Diet. Class. d'Hist. Nat.' 

 Of the above species we have not had the opportunity of 

 examining a specimen. It exists, however, in the Museum, 

 at Paris. 



S. latibarbatus. 



General colour deep blackish grey, becoming paler on the back of the 

 neck and head ; loins, hinder part of thighs, and tail, pale grey ; the end of 

 the tail becoming almost white ; a greyish white broadly triangular beard, 

 on the sides of the face and chin ; under parts light grey. Hands and feet 

 dull black, as are also the face and superciliary row of hairs. 

 Length of a young specimen 16 inches: tail 20 incher. 

 Habitat India ; (Ceylon).
