The other skin was a new species of the genus Cercopithecus, for 

 which the name of Cere. Campbelli was proposed, with the following 

 character. 



Cercopithecus Campbelli. Cere, vellere perlongo, subsericeo, 

 per dorsum medium diviso ; capite corporeque anteriore grises- 

 centi-olivaceis, pilis nigro Jlavoque annularis; corpore posteriore 

 femoribusque extus intense cineraceis ; guld, abdomine, artubus- 

 que internis albis ; brachiis externe nigris ; caudd pilis nigris et 

 sordide Jlavis indutd, apice nigro, pilisque longioribus instructo. 



Longitudo capitis corporisque, 20 unc; caud<s, 28 unc. 



Hab. Sierra Leone. 



"This species appears to be most closely allied to the Cercopithecus 

 Pogonias of Mr. Bennett ; it has not, however, the black back which 

 serves to characterize that animal. 



" The most remarkable characters in this animal are its long fur, 

 and the hairs being divided 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 and a half inches ; on the hinder half of the back, how-_ 

 ever, they exceed three inches. These hairs are grey at the base, 

 and the remaining portion of each hair is black, with broad yellow 

 rings, the latter colour prevailing. On the posterior half of the 

 body, and the outer side of the hinder legs, the hairs are of a deep 

 slate grey, and almost of an uniform colour ; some of those on the 

 middle of the back are obscurely freckled with deep yellow, and 

 those on the thigh are very indistinctly freckled with white. The 

 belly, inner side of limbs, fore part of thigh, chest and throat are 

 white. The hairs of the cheeks and sides of neck are very long, and 

 of a greyish -white colour, grizzled towards the apex with black and 

 yellow ; some whitish hairs tipped with black are observable across 

 the fore part of the forehead. The inner side of the ears is fur- 

 nished with very long hairs of a greyish-white colour, obscurely an- 

 nulated with grey and pale yellow; these hairs vary from three 

 quarters to one inch in length. The fore legs are black externally, 

 and the hairs on this part are comparatively short. The hairs on 

 the upper side of the tail are grizzled with black and dirty yellow, 

 and on the under side with black and brownish-white. The apical 

 portion of the tail, which is furnished with longish hairs, (as in Cere. 

 Pogonias), is black, the black hairs occupying about one third of 

 the whole length of the tail. 



"I have named this animal after the late Governor of Sierra Leone, 

 Major Campbell, that gentleman being its discoverer."
