118 Mr. 0. Thomas on small Mammals 



with the especial wish to obtain a male Derby's eland for 

 the National Museum. In this latter purpose he was un- 

 successful, but he brought home a female eland, besides 

 specimens of the local buffalo, havtebeest, water-buck, roan 

 antelope, oribi, and blue-backed duiker. 



Of small mammals he obtained a considerable series, and 

 tliese prove to be of such interest as to deserve a special list, 

 in addition to the descriptions already published of Tatera 

 gambiana, Arvicanthis linulus, and Uranomys oioeni*. 



Mr. Fenwick Owen^s collecting was mostly done in French 

 Gambia, on the upper part of the river of that name ; but 

 some of the specimens came from rather further south, in the 

 Fouta Djallon district of French Guinea — a region about 

 3000-4000 feet in altitude. More complete collections from 

 this latter region might prove of great interest. 



Mr. Owen was accompanied by Mr. G. Russell Roberts, 

 who assisted in m-aking the collection. 



The whole series has been presented to the National 

 Museum by Mr. Owen, and forms a very valuable addition 

 to its African collections.
