" The small bushy tail, the character of the fur, -vvhich is short and 

 closely adpressed, and the colouring, all indicate in this species, I 

 imagine, an affinity to the Ant. scr2Jo^a,Avithwhichit appears to agree 

 in size. The brown neck, deeper and richer colouring, and the ab- 

 sence of white markings on the body, however, will serve to distin- 

 guish it from that species. As in Ant. scripta, there is a black line 

 along the spine of the back. 



" The skin from which the above description is taken is ■without 

 head or limbs. The length from the shoulders to the root of the 

 tail is about two feet eight inches. The tail is about four and a 

 half inches. 



" If my conjectures regarding the aifinities of this animal prove 

 correct, it -vvill belong to the sub- genus Tragelaphus of Hamilton 

 Smith, or to the more extended group to which Mr. Ogilby has ap- 

 plied the name of Calliope. 



" I have taken the liberty of naming this animal after the author 

 lašt mentioned, whose careful researches in the Ruminant animals 

 have thrown considerable light on the afhnities of the species." 



Mr."Waterhouse then proceeded to notice two skins which had been 

 just brought from Sierra Leone by Major Henry Dundas Campbell, 

 (late Governor of that Colony,) and sent by him for exhibition at 

 the Society's evening meeting, Avith a promise on the part of Major 

 Campbell to present them to the Museum, in the event of bis being 

 able to make an arrangement vvith a party to whom he had parted 

 with them as an article of commerce. One of these specimens was 

 a remarkably fine skin of a species of Colobus, described by Mr. 

 Ogilby in the Society's Proceedings under the name of Col. ursinus ; 

 the skin, however, upon which Mr. Ogilby founded his species was 

 imperfect, and until the opportunity afForded by , the inspection of 

 the present specimen, nothing \vas known of the colour of the head 

 and face, ■which prove to be greyish white. 



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

 Tvhich the name of Cerc. Campbelli vfas proposed, "vvith the following 

 character. 



Cercopithecus Campbelli. Cerc. vellere perlongo, subsericeo, 

 per dorsum medium diviso ; capite corporeąue anteriore grises- 

 centi-oltvaceis, pilis nigro Jlavoque annulatis; corpore posteriore

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

 sordide Jlavią indutd, apice nigro, pilisqtie longioribus instructo.

"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 mostremarkablecharacters in this animal are its long fur.
