3. P. h. somdliensis: Known only from British Somaliland (Zeila 

 on the coast and Somadu on the inland plateau). This race appears 

 (from contradictory statements in literature) to differ from the other 

 two chiefly in being smaller, the color characters being open to 

 question. 



The present form has an altitudinal range of from fairly low 

 down in the hot tropical valleys up to nearly 10,000 feet in the 

 mountams, which accounts for its general distribution in Ethiopia. 

 It appears to reach its maximum in population density between 7,000 

 and 9,000 feet, according to Neumann.'^* Zedlitz " found it fairly 

 ubiquitous in northern Ethiopia and judged that the breeding season 

 in the Eritrean-Danakil coastlands was during January and Feb- 

 ruary, while in the highlands of Bogosland and Tigi-e it appeared 

 to occur late in summer. Mearns collected a mated pair on March 

 10 at Aletta.
