Mr. Waterhou3e brought before the notice of the Meeting an ex- 

 tremely interesting series of skins of Mammalia, which had recently 

 been given to the Society's Museum by George Knapp, Esq., who 

 had received them from the Island of Fernando Po. The collection 

 included the following seven species, which were considered by Mr. 

 Waterhouse as hitherto undescribed ; namely, two new Colobi, form- 

 ing a most important addition to that group of Quadrumana of ■which 

 our knowledge i s so extreniely limited, from the small number of skins 

 brought to Europe ; two new species of Cercopithecus ; a new An- 

 telope, a new Otter, and a new species of the genus Genetta. 



These were severally named by Mr. Waterhouse, and the follow- 

 ing descriptions and specific characters communicated to the Meet- 

 ing for publication in the Society's proceedings.

" The prevailing colour is bright rūsty -red; the head, back of the 

 neck, and the centrai portion of the back, areblack; the cheeks and 

 throat are ■vvhite or dirty white ; chest, fore part of the shoulders, 

 the under parts of body and inner side of the limbs are dirty yėllow; 

 inner side of the thighs whitish ; the hairs of the taU are bro^vnish 

 black. The fur is long and not very glossy; that on the head and 

 fore parts of the body being the longest. There is no soft under 

 fur ; the hairs are of an uniform colour to the base, or at least in a 

 very sUght degree paler at that part. The portion of the back which 

 is described as black partakes sŪghtly of the rūsty hue which prevails 

 over the other parts of the body ; it occupies but a narrow portion 

 of the back, and blends indistinctly into the rust colour. The lower 

 parts of the limbs are removed, but as they are black at the knee, 

 and also assume a deep hue below the elbow, it is probable the re- 

 maining portions are black externally ; but internally, as far as can 

 be seen, the limbs are yellowish or yellow white. 



" There was scarcely any perceptible difFerence in the colouring in 

 all the specimens examined by me, from Fernando Po, amounting to 

 about eight in number. They invariably had white or dirty-white 

 cheeks and throat. 



" This species is the nearest y et fourid to the Bay Monkey of Pen- 

 nant, but differs in having the throat and cheeks white, and in ha-
