dark bases and white tips, contrasting with the tendency to uniform 

 white in hildehranti Peters; tail dark brown above, lighter below; 

 flesh and hair of wrists and ankles cinnamon-brown, becoming lighter 

 on distal portions of feet and passing into white on the toes; claws 

 light, translucent, or speckled with darker color. 



The collection includes a very young specimen (No. 32 9 ) from the 

 type-locality, which shows the same ocular rings and dark ankles. 



8. E. rufidorsalis ankoberensis subsp. nov. 



Type from Ankober, Shoa, Abyssinia, altitude 7,500 feet. (Original

General Characters. — Comparatively large size of body and skull, 

 dark ocular rings and ankles. 



Skull. — Compared with other races of E. concha Smith this is 

 longer and broader, showing greater development of the brain-case 

 and nasals. 



Pelage. — Upper dorsal area prevalently hair-brown ^^ in color, slightly 

 speckled with buff-tipped hair; sides bright buffy; under parts pallid 

 mouse-gray; dark ocular rings prominent, tip of nose white, ears very

9. E. hildebranti gardulensis subsp. nov. 



Type from Gardula, Southern Abyssinia; altitude 4,000 feet. 

 (Original field-number 44, (^, D. G. R., March 27, 1912.) 



General Characters. — Slightly larger, but agreeing in the propor- 

 tions of skull and body with the series of E. nenmani Heller from the 

 northern Guaso Nyiro, in U. S. National Museum, the general appear- 

 ance of the upper paits resembling E. neumanni, and being almost 

 identical with that of the slightly smaller E. panya Heller /. c, from 

 Juja Farm, and the lower surface differing from both E. neumanni and 

 E. panya by the entire lack of the usual buffy over-wash. 



Skull. — Proportions very similar to, but slightly larger than, those 

 of E. neumani Heller. 



Pelage. — Dorsal area generally avellaneous," median portion dark 

 to blackish, due to thick intermixing of longer black hair (the light- 

 tipped fur is never surtipped with black as in Arvicanthis and some
