Lado: Rhino Camp, 21, including 10 in alcohol (Loring). 



Uganda: Butiaba, 3, including 1 in alcohol (Loring, Heller); 

 Kampala, 1 (Loring). 



This dark form of hellus seems to be confined to the west side of 

 the Nile in the latitude of the type locality. Rhino Camp; but further 

 south, in Uganda, it is found in the region between Albert Nyanza and 

 Victoria Nyanza. It is readily separable from Mus emesi by its smaller 

 size and smaller skull.
