1907.] MOXKEYS OF THE GENUS CERCOPITHECUS. 695 



imperfect skins sent to Dr. Sclater by Vice-Consul (now Sir Alfred) 

 Sharpe from Lake Mwern ; a third, sent hj the same collector, 

 to the British Museum (No. 92.2.6.2), and ticketed " Nyasaland." 

 The fourth and best of the series is also in the British Museum 

 (No. 95.7.12.1); it was sent to that institution by Mr. F. S. 

 Arnot, who procured it in the Kundilungo Mountains, west of 

 Lake Mweru. 



The black belly, limbs, and shoulders, the predominance of 

 black on the head, the white chin and thx-oat, and the absence of 

 red from the dorsal area, enforce the inclusion of this species in 

 the Leucampyx-group of the genus.

Loc. Near Lake Kivu [Powell Cotton) ; north of Lake Kivu 

 {Matschie^. 



The above-given description is taken from two flat native- 

 prepared skins in the British Museum ^iresented by Major Powell 

 Cotton. ^ 



This sj)ecies differs from other members of the Leucampyx- 

 group by the rufous tint of the underside and of the area 

 round the base of tlie tail. It might almost be described as an 

 erythristic form of C. leuc(mij)yx stuhlmanni. 



The NICTITANS-group. 



Rhinostict'us Trouess. (in part.). 



Closely resembling the Leucampyx-group in general coloration, 

 but with the hairs on the nose forming a. well-defined large white 

 or yellowish spot, sharply differentiated from the darker-coloured 

 upper and lower lips, and with strongly convex upper border. 

 Distinguished from the Petaurista-group by the absence of the 

 black brow-band and of a black stripe crossing the temple from 

 the eye to the ear. No black strij^e on the cheeks, which are 

 uniformly speckled greenish black. Head and nape darker than 

 the back, which is blackish speckled with grey, but scarcely 

 yellowish. Tail the same colour above as below, black throughout 

 the greater part of its length. Fore legs black. Belly gieyish 

 black and srizzled ; throat and sometimes the chest whitish.
