The subspecies nigrimamts was based upon a single example 

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

It is interesting to note tbat tbe two subspecies most distinct 

 from each other, namely, U. f. Jlavimanus and U. f. nigrimanus, 

 occur iu the same locality, whei'eas the subspecies intermediate 

 between them is found elsewhere.
