Sou Ian, l)iit dilTLM-.s by its rathor shorter ear.'^, longer tall, and 

 slii^litly paler coloration. The two species J^. gamhianus and 

 E. daltoni evidently stand to each other in the same relation- 

 shi]) that E. hlainei and E. hutleri do on the Nile, and it is 

 l)0.ssible that links will prove to connect the corresponding 

 species when the intermediate country is explored. 



A specimen of this species has been in the Museum since 

 1844, where it was obtained by Whitfield and presented by 

 Lord Derby. At one time it was labelled " Mus gamhinnnSj' 

 and thou^-h I cannot find that this name was ever published, 

 I think it wiser to use the same term, in case I have over- 

 looked it.

This is the most interesting animal of the collection, 

 as it belongs to a genus only previously represented by a 

 single Central African species, U. jWc?/, Dollm., and it forms 

 therefore quite a fresh addition to the West African fauna. 

 A description of it was published last year (l. c).
