Mammals from SomaliJand. 249 



(6) Otocyon megalotisj Desm. 

 a. Lehello, lOtli June. 



(7) Xerus dahagala, Heugl. 



a. Lehello, 12th June. 



Dr. Jentink, in his well-known revision of the African 

 squirrels ('Notes Leyden Museum,' 1882, p. 41), gives this 

 name as a synonym of X. rutilus ; this, I think, is not doing 

 justice to a form so strikingly different in coloration. The 

 torm described by M. Mihie-E (wards (Liev. et Mag. Zool. 

 1867, p. 229) as X. Jlavus belongs no doubt to the present 

 species. 



(8) GerliUus ruherrimus, Rhoads (?) = G. pusilluSj Peters. 



a. Bally Maroli (5000 feet), a little to west of Eyk. 



I use the above name for this Gerbil as it has been 

 applied to an animal from an adjacent locality ; at the same 

 time I am not at all sure that it is in any way distinct from 

 G. puaiUus, Pet., which comes from Taita in British East 

 Africa.

 the back tipped with black, sides purer; bases of the hairs on 

 the back and the top of the iiead slate-coloured ; all the under-

 legs the white hairs are tipped with fawn; the white spots at 

 the base of the ears and above the eyes distinct ; tail darker 

 above than below, rather sparingly haired ; feet not very 

 thickly covered with white hairs; nails darkish horn-colour j
