Miiller, in his Tydschrift voor Natuurlijke, figures and describes a 

 Semnopithecus, which he met with in Borneo, under the title of S. 

 chrysomelas, but which, there can be little doubt, is identical with the S. 

 femoralis of Horsefield. The subjoined details, given by the former 

 traveller, agree with those afforded by the specimen (also from Borneo), 

 which has been already mentioned, as recently added to the collection of 

 the Zoological Society, London. 



This species, in size, and the slenderness of the limbs, resembles the 

 Entellus. The body throughout, with the tail, is uniformly black, 

 excepting the interior of the arms, the lower part of the abdomen, and 

 the basal portion of the tail, on all of which the fur is of an ochreous 

 yellow tint. Of the latter colour, a well defined streak descends, tapering 

 along the posterior sides of the inner margins of the hind legs, from the 

 top to the heels ; on the hands, also, as well as on the breast, silvery 

 yellow hairs are mixed with the black colouring ; on the top of the head 

 the hairs form a comb-like crest, which extends from the occiput to the 

 neck ; the black hairs, both on the crown of the head, and also behind 

 and under the ears, are elongated, by which means a sort of whisker is 

 constituted on each side of the face ; the colour of the face, of the ears, 

 and of the palms, is sooty black, as in S. maurus.

Miiller states that his description was taken from the prepared speci- 

 men of an adult female ; which, however, perfectly agreed in colouring 

 with another adult female, and also with a male, of the same size, pro- 

 cured by M. Diard. A third example, obtained by the same traveller, at 

 Pontianak, and, according to Miiller, evidently belonging to this species, 

 was found to differ in some degree from the other individuals, being of 

 a dirty-reddish tint over the whole body, with many black hairs mixed 

 among the yellow ones on the head and neck ; while, on the outside of the 

 limbs, and especially on the hands, smaller or larger spots of black were 

 scattered. This specimen had a very imperfect covering of fur, and 

 appeared to have been in a diseased state when killed. 



GENERAL HISTORY. In its habits, the White - thighed Monkey 

 resembles the rest of the genus : it tenants the forests, living in troops, 

 and is active in escaping from pursuit. It has never been imported alive 

 into Europe.
