XXXIII. — On a new Monkey from Nyasaland. 

 By Oldfield Thomas, F.U.S. 



Among a small collection of mammal-skins from Nyasaland 

 presented by Mrs. H. R. Mill to the National Museum there 

 occurs an example of a new monkey of the Cercopithecus 

 albigularis group, which I propose to name in honour of its 

 donor. 



Cercopithecus FrancescWf sp. n. 



General characters of C. albigularis^ but smaller. Colour 

 of body much darker and greyer, with less yellowish — the 

 yellow being restricted to a narrow area along the back, and 

 the hairs even then being only quite narrowly ringed sub- 

 terminally with this colour; their basal three-fourths dark 

 slaty grey and their tips black. Elsewhere, on head, nape, 

 shoulders, flanks, and hips, the colour is dark blackish grey, 

 finely grizzled with whitish. Hairs bordering ears on inner 

 side bright reddish or fulvous. Usual light neck-patch 

 present, dull white, not specially sharply defined, and not 

 encroaching upon the back of the neck. Limbs below elbows 

 and knees black. Tail long, its base grizzled like the body, 

 the rest dull black. 



Approximate dimensions of the type, a native-made flat 

 skin : — 



Head and body 450 millim., tail 620. 



Hob. Near Mt. Waller, western side of Lake Nyasa; high 

 up on the plateau. 



Type. B.M. no. 2. 7. 24. 1. Collected by the Rev. James 

 Henderson, and presented by Mrs. Frances Mill.
