Specimens of the ascanius group are so rare that I am not 

 able to make a detailed comparison of this handsome monkey 

 with the various forms which have been described, but it 

 would seem to be diHercnt from all by the reduction of the 

 black on the cheeks. Its white underside, butfy nose-spot, 

 and red-ended sharply contrasted tricolor tail render this 

 monkey a very striking object, but how far these characters 

 are aflected by age remains to be proved. 



Rousettiis kempi, sp. n. 



Allied to, but with heavier teeth than, R. lanosus. 



External ch:iraetcrs as in the Ruwcnzori ]\lountain Fruit- 

 bat, R. lanoius, except that the long hairs of the back, rump, 

 and interfcmoral region tend to be grcver. Palate-ridges 

 4—3—1. 



Skull as in lanosus, the brain-case equally strongly 

 deflected. 



Teeth larger, broader, and heavier throughout, more as in 

 ordinary Kousets, not so highly specialized as in R. lanosus. 

 Incisors, canines, and anteriur premolars as in lanosus. 

 F* 3 mm. in horizontal length as against 24- in lanosus;

This is evidently the Elgon representative of the 

 Ruwcnzori A. lanosus ; the Sh(;a specimen mentioned by 

 Dr. Andersen * would appear, as is natural, to be the same 

 as the Elgon rather than the Kuweuzori species.
