Three skins, one imperfect, the other two perfect, with the exception 

 of the hands, the originals of Mr. Waterhouse's description, exist in the 

 museum of the Zoological Society, London (Nos. 28 A, 28 A, a, in Suppl. 

 Catalogue Mamm. 1839). They were presented by G. Knapp, Esq. The 

 uniform black colour of this species will at once distinguish it from Col. 

 ursinus, and Col. leucomeros, its nearest allies. 



GENERAL HISTORY. The specimens, from which the original descrip- 

 tion was taken, were brought from Fernando Po ; but no details regarding 

 the history of the species accompanied them ; and, consequently, the habits 

 and manners of this species are among the desiderata of the naturalist.

SPECIFIC CHARACTERS. General colour ferruginous ; the top of the head, the tail, and 



limbs, externally blackish. 

 LOCALITY. Sierra Leone. 



DESCRIPTION. The crown of the head is black ; the back is of a 

 deep bay colour ; the outside of the limbs are black ; the cheeks, the 

 under part of the body, and the legs are of a very bright bay ; the tail is 

 very long, slender, and black. 



The above is, in substance, Pennant's description of a specimen 

 formerly in the Leverian Museum, brought by Mr. Smeatham, from 

 Sierra Leone. Several species, agreeing more or less closely with the 

 above description of the Bay Monkey, by Pennant, but still affording good 

 grounds on which to regard them as distinct, have to be noticed, and in 

 the account of each respectively, these specific differences from the pre- 

 sent species will be pointed out. 



GENERAL HISTORY. This species rests solely upon Pennant's brief 

 description of a specimen formerly in the Leverian Museum ; but, with the 

 fact of its having been brought from Sierra Leone, our information ends ; 

 with respect to the habits and manners of the animal in its native country, 

 nothing was collected by its first describer, nor has anything been sub- 

 sequently ascertained.
