in the brow-band. In the continuity and completeness of the jet- 

 black hue of the head, nape, and shoulders it resembles the types 

 of C. I. otolevcus and nigrigenis, and, I presume, also of G. I. stukl- 

 ')nanni and of typical C. leacampyx. It leads from the foregoing, 

 which have at least some white in the brow-band, to the two 

 following subspecies, in which no white is therein traceable. 

 Additional specimens may prove this example to be worthy of 

 recognition as a distinct subspecies. The head and body of the 

 Mpanga Forest specimen measui-e 574 mm. ( = 23 inches) and the 

 tail 900 mm. ( = 36 inches). 



It should be stated that, in the diagnosis of C. stvMmanni, 

 Matschie does not mention the presence of a black bar across the 

 chest, which is present in the example from the Mpanga Forest 

 and also in other specimens of this group of Cercopithecus, where 

 the belly and chest are of a greyish hvie. 



Subsp. CARKUTHERSI, nov. 



Closely related to C. I. stuhhncmni, but distinguishable by the 

 absence of white in the brow-band and the less amount of blackness 

 of the area between the shoulders, which is ticked with grey, 

 being only a little darker than the back and decidedly lighter 

 than the head. The belly also is less speckled with grey, and 

 hence darker. 



Loc. Ruwenzori, east side, 10,000 ft. [D. Carruthers). Type in 

 Brit. Mus. 



There is also a native-j^repai'ed skin, apparently of the same 

 subspecies, in the British Museum, ticketed " Uganda ((x. ^. >S'coii 

 Elliot)." Possibly it also came from Ruwenzori. 



Subsp. DOGGETTI, nOV. 



Summit of head, including area round ears, and nape of neck 

 to area between shoulders, where speckling commences, jet-black. 

 "Whiskers and brow-band olive-grey ticked with black. Median 

 area of back greenish grey, speckled ; sacral region with reddish- 

 brown tinge, but speckled. >Sides of body speckled, but greyer than 

 dorsal area. Tail nearly black at the distal end, the i-est greyish 

 above and below, speckled only at the base. Fore leg and hands 

 jet-black externally; hind leg from hip blackish grey, speckled; 

 foot quite black. Belly and inside of limbs ashy grey ; a dark 

 band crossing the region of the collar-bones. Middle line of 

 throat white, the white narrower than in the type of G. omensis. 

 Head and body 487 mm., tail 655 mm. (? imperfect). 



Loc. S.W. Ankole, between Lakes Victoria and Albert Edward 

 (jr. Doggett). 



A single female specimen in the collection of the British 

 Museum. 



This subspecies is characterised by the rufous speckling at the 

 base of the tail, the extension of the speckling, although indis- 

 tinct, to the tip of that organ, the yellower hue of the back as 

 compared with the sides, and the greyness of the sides of the body 

 an.d of the belly.
