The subspecies nigrimanus was based upon a single example 

 from Mombasa (see Proc. Zool. Soc. 1890, p. 130, pi. xiv. fig. 2). 

 U. flavlmanus is based upon a specimen in the British Musevim 

 obtained by Mr. J. Wilson at Mombasa in British East Africa. 



It is interesting to note that the two subspecies most distinct 

 from each other, namel}'-, U. f. flavimanus and U. f. nigrimanus, 

 occur in the same locality, whereas the subspecies intermediate 

 between them is found elsewhere.
