XXVII. — Notes on the Genus Cricetomys, with Descriptions 

 of Four new Forms. By Martin A. C. HlNTON. 



(Published by permission of the Trustees of the British Museum.) 



In determining some specimens of Cricetomys from Zanzi- 

 bar and the southern part of the Congo Basin, I have had 

 occasion to work through all the material in the British 

 Museum. This material, although extensive, is scarcely 

 sufficient for an attempt to revise the whole genus. Many 

 forms have been described, but with one exception all have 

 been treated as mere subspecies of C. gambianus by modern 

 workers — in my opinion, four species at least are at present 

 included under the name. 



1. Cricetomys gambianus, Waterhouse. 



An examination of Waterhouse's type shows that the name 

 gambianus is applicable only to the harsh-furred white- 

 bellied forms ranging eastwards from the Gambia and
