3. R. a. granti. — Karroo district of Cape Province north to the 

 Orange Free State and the Transvaal; darker than africamis, the 

 throat streaks heavier, the abdomen rufous buff, the inner primaries 

 more rufous in color. 



4. E. a. bisignatus. — Angola; characterized by small size (wing 

 133-142 as against 147-161 millimeters in africanus) and pale 

 coloration. 



5. E. a. illustris. — Central Tanganyika Territory; nearest to 

 hisig7iatus but paler, less rufous, more grayish. 



6. E. a. gracilis. — Dry inland districts of Kenya Colony and 

 northern Tanganyika Territory; characterized by a combination of 

 characters ; small size as in hisignahis and illustris and darker color- 

 ation (not as dark, however, as in africanus., sJiaryei., or granti). 



7. E. a. hartingi. — Somaliland; a very rufous race with the size 

 characters of bisignatus, illustris, and gracilis. 



8. E. a. raffertyi. — Hawash district, Ethiopia; size as in hartingi, 

 but much less rufous, more grayish above, much darker; differs 

 from bisignatus in being less tawny on the breast and on the back, 

 and grayer above. 



The type is in somewhat worn plumage, while the other is fresh 

 and has wider light margins to the feathers of the upper parts. 

 The difference is particularly noticeable on the crown, the absence 

 of light edgings giving the type a darker looking head than the 

 paratype. The upper wing coverts of the type are new, and con- 

 trast markedly with the worn scapulars and interscapulars. 



The measurements of the two birds are as follows: Type — wing 

 147, tail 63, culmen 14, tarsus 46 millimeters. Paratype — wing 137, 

 tail 61, culmen 14, tarsus 45 millimeters. 



Apparently these two birds constitute the sole records for the 

 species in Ethiopia, and the only known specimens of 7'affertyi in 

 existence.
