Admitting that the species, described by Geoffroy as C. auratus, is 

 identical with the S. pyrrhus of Horsefield, it will follow that the latter 

 term must merge into a synonym ; but the black marks which Geoffroy 

 describes as characteristic of the S. auratus are no longer to be con- 

 sidered in such a light, and cannot be received as specific distinctions. 



GENERAL HISTORY. The habits and manners of this beautiful species 

 present the same features as those of the other Semnopitheci ; but the 

 animal is little known, and has never been brought alive to Europe.

SPECIFIC CHARACTERS General colour, fine red, paler on the back ; limbs and apical part 

 of tail, blackish red; throat and abdomen, greyish yellow; vertical crest very long; 

 a naked mark on the forehead, of a livid white; face black, surrounded by a black 

 beard. 



LOCALITY. Borneo. 



DESCRIPTION. The limbs of this species are very slender ; and it is 

 characteristically marked, not only by this meagreness of form, but also 

 by the presence of a high but narrow crest, which rises over the top of 

 the head like a comb, and then falls over the occiput as far as the neck ; 

 it has, besides, above the nose, on the forehead, a large, naked spot, which 

 is of a bluish white, or milky tint, contrasting very strongly with the 

 small, dull, black face, surrounded by a long black beard on both sides of 

 the cheeks. The fur, in adults, is generally dark red, but on the back, 

 especially toward its anterior portion, the colour is lighter, inclining more 

 or less to a yellowish grey ; on the extremity of the tail, and toward the 

 lower portion of the limbs, the general colour assumes, gradually, a dark, 

 rusty-black tint, which on the hands of the anterior extremities becomes 

 almost pure black ; the throat, breast, and entire abdomen are yellowish 

 grey ; the iris is brown.

GENERAL HISTORY. This beautiful species surpasses, in the elegance 

 of its form, and in the agility and quickness of its movements, most of the 

 others of the genus. The Bejadjoo Dayaks, on the south coast of Borneo,
