A medium sized rat with the outward characters and 

 proportions very much as in hindei, Thos. from British 

 East Africa. Fur soft and glossy ; hairs of back about 10 

 mm. in length. General colour bright tawny, dulled by 

 the dark slate almost black bases of the hairs showing 

 through ; paler on the sides. Cheeks, throat and belly 

 dull white (the hairs with slatey bases), the last not sharply 

 defined from the upper side. Tail short, above brown,, 

 darkening distally to almost black, below dull white also 

 darkening towards the tip. 



The skull characters on the whole as in hindei but the 

 anteorbital plate, though " not concave below " as in Jiindei y 

 shows a distinct angle where the upper and anterior edges 

 meet as in nyikce. The palate, however, does not extend 

 backwards as in hindei, not even so much so as in nyikce ; 

 both molars and bullae larger than in either hindei or nyikce. 



The dimensions are as follows.

Though geographically nyikce intervenes, watambcz 

 certainly more nearly resembles Jiindei, the brighter 

 colouring and larger molars and bullae serve to distinguish
