The discovery of E. Jacksotii in West Africa is somewhat 

 of a surprise, but I can find no character of importance to

 Multimammate group. 



12. Epimys sp. (?).

13. Acomys sp.

A dark-coloured species of medium size. 



Size rather smaller than in the large G. lechei and its allies, 

 larger than in the majority of the species. Fur soft and fine ; 

 hairs of back about 9 mm. in length. General colour daik, 

 conspicuously different from the light-coloured G. zechi of

 narrowed posteriorly, not running back to a point ; pre-
