head the hairs are yellowish, ringed with black; a few black hairs 

 occupy the middle line ; and on each side, passing from above the eye to 

 the ear, is a broad patch of black ; the whiskers expand very broadly, 

 forming a large full tuft on each side of the face, commencing close under 

 the eye, and covering the whole cheek, their direction being downward 

 and outward ; the hairs composing them are of a dirty yellowish white, 

 occasionally, but very sparingly, ringed with dusky black ; the ear has 

 internally a long tuft of hairs of the same colour with those of the 

 whiskers ; the outer side of the hinder limbs, the hands excepted, is 

 yellowish, grizzled with black, the colour being intermediate in intensity 

 between the lightest portion of the -sides, and the whiskers ; the under 

 surface of the body, the insides of the limbs, and the under surface of 

 the proximal two-thirds of the tail, are reddish yellow.

GENERAL HISTORY. The original of Mr. Bennett's description (No. 

 33, in Cat. Mamm. 1838) was, for many years, the only example known 

 of the present species. Recently, however, a second specimen has been 

 added to the museum of the Zoological Society, London. It was 

 obtained in Fernando Po, and presented, with other interesting skins, by 

 G. Knapp, Esq. No account of the habits of the animal has been yet 

 procured.

DESCRIPTION. Description of specimen (No. 33 c., in Suppl. Cat. 

 Mamm. 1839) in the museum of the Zoological Society, LondDn : This 

 species appears to be most closely allied to the Cercopithecus Pogonias of 

 Mr. Bennett ; but it has not the black back which serves to distinguish 

 that animal. 



The most remarkable characters, of the Cere. Campbellii are its long fur, 

 and the division of the hairs on the back, as in most of the species of the 

 genus Colobus. The average length of the hairs of the back is about 

 two inches and a half; on the hinder half of the back, however, they 

 exceed three inches. These hairs are grey at the base, and the remaining
