Hab. Harich, near Lake Baringo, British East Africa. 

 Altitude 3000 feet. 



Type. Adult. B.M. no. 9. 5. 13. 3. Original number 2. 

 Collected in December 1908 by Mr. K. R. Dundas, and pre- 

 sented by him to the British Museum. 



In addition to the type Mr. Dundas obtained a second 

 specimen from the same locality, quite similar in colour to the 

 type. 



This Baringo species may be regarded as allied to the 

 Somaliland form E. somalicus, but is distinguished by the 

 more buffy coloration of the flanks and darker upperside of 

 the tail. From E. boranus, Thos., it is readily separated by 

 its far paler upper surface and pure white belly. 



1 have named this species after Mr. K. K. Dundas, whose 

 collections from Baringo and Mumias have proved to be of 

 considerable interest and of great value as regards the geogra- 

 phical distribution of some of the East-African mammals.
