ized by possessing cheek-pouches. But this third division un- 

 questionably presents a nearer structural approach to the first 

 than does the second ; and^ so far as I have observed^ the intellect 

 is also decidedly of a superior grade. 1 have next to describe an 

 apparently new species of the African genus Cercopithecus. 



Cercopithecus chrysurus, Nobis. — This belongs to the particular 

 minor group exemplified by C. sabceus, and would seem to be 

 nearly allied both to that species and to the C. Tantalus, Ogilby, 

 P. Z. S. 1841, p. 33, the tail of which is stated in the Latin 

 diagnosis to be yellow at tip, while in the more detailed verna- 

 cular description this is said to be " brown at the base, light gray 

 at the tip." In the species now described, the terminal third of 

 the tail is bright yellowish ferruginous, as I believe in C. sabceus. 

 The specimen is a male, and measures about nineteen inches from 

 forehead to base of tail, the tail about twenty-four inches ; from 

 elbow to tip of hand nine inches, kiltee to heel seven and a quar- 

 ter, and foot five inches. Colour grizzled yellowish brown, the 

 hair fine and soft at base, with the terminal half comparatively 

 coarse and rigid, and broadly annulated first with black, then 

 fulvous, and finally tipped with black ; for the most part about 

 two inches and a quarter long, but exceeding three inches on the 

 sides towards the flanks : the whiskers, with the entire under- 

 parts and inside of the limbs, are dingy yellowish white : the 

 fore-arm and leg grayer, or less yellowish than the parts above, 

 and the hands and feet infuscated. Face almost naked, having 

 only a few scattered hairs, but a narrow supercilium of long black 

 hairs across the brow. The upper surface of the tail is rather 

 darker than the back for the first two-thirds of its length, and 

 then passes into bright yellowish ferruginous, which on the under 

 surface of the tail is continued nearly to its base, weakening 

 however in intensity ; the extreme tip of the tail is wanting in the 

 specimen. Length of the skull four inches and a half, and 

 breadth across the zygomata two inches and three-quarters ; ver- 

 tical height two inches and five-eighths ; length of bony palate 

 an inch and a half, and breadth seven-eighths of an inch. Ha- 

 bitat unknown. 



Leinuridce. — The Stenops gracilis is usually assigned to Ceylon, 

 and the Nycticebus tardigradus to Bengal. The latter however 

 certainly does not occur in the lower part of Bengal, but may 

 perhaps exist in the hilly regions. Dr. Walker includes it in 

 his catalogue of Assamese mammalia; and upon referring to 

 the late Dr. Buchanan Hamilton's MSS., I find what I consider 

 to mean this species noticed as occurring in Chittagong, where 

 it is said to be rare and solitary, inhabiting trees ; in Bungpore 

 also very scarce, and said to have been seen in the hilly coun- 

 tries to the south and east of the Boorhampooter by some natives, 

 who recognised it by the Hindustanee name Shiriminda Billi,
