 inces of the Sudan, south to extreme northwestern Uganda, and in 

 Kenya Colony to the Northern Guaso Nyiro and Lekiundu Rivers,

 Lort Phillips found it common at the coast at Berbera and also on the 

 highest elevations of the Goolis Mountains in British Somaliland, 

 and von Heuglin recorded it up to 12,000 feet in the Ethiopian moun-
