154 THE tf ATUBAL HISTORY OF 



key ; of small size, above of a bluish-green, beneath 

 grayish-white. 



The second is named Colobus by Illiger,* remark- 

 able for having only four fingers upon the upper ex- 

 tremities, and in this respect representing Ateles^ of 

 the New World, to which it also comes near in the 

 shortness of the muzzle, and comparative shortness of 

 the face. In other respects it resembles the Guenons. 



Three species are described. They are natives of 

 Africa, but little is known of their habits or locality. 



The type of this genus may be seen in the Simia 

 pdycomos, Schreber, the full-bottomed monkey of 

 Pennant, black, with longer hair covering the neck, 

 in the form of a mane. It inhabits the forests of 

 Guinea and Sierra Leone. The next is the bay 

 monkey, Colobus ferruginosus, which has been 

 thought by some to be merely a variety of the pre- 

 ceding ; and the third \v, an unfigured species, dedi- 

 c^ted by M. Kuhl to M. Temminfk (Colobus Tern- 

 i+inckii, Kuhl.) It formed part ol the collection of 

 Mr Bullock, and, at the dispersion of that valuable 

 museum, passed to that of Temminck. The upper 

 parts of the head, ne<'k, back, and shoulders, black, the 

 limbs clear reddish, and the under parts having a tinge 

 of tawny yellow. The native country unknown. 



It may be remarked that this genus is placed by 

 I]liger after the Cynocephali, and next that of Atele,
