north through western Urundi and Ruanda to the southern end of 

 the Ruwenzori range. Similar to jehelensis but slightly darker, size 

 as in jebeleiisis. 



(^) C. s. hilgerti. — Southern British Somaliland, western Italian 

 Somaliland, and the eastern portion of Ethiopia (west to Dire Daoua, 

 Sadi Malka, the Ha wash River, and the Arussi Plateau) south to 

 the Kenya Colony boundary. This is a dark race with deep buffy, 

 not grayish or whitish auriculars; wing, 103 millimeters in male (1 

 specimen), 93-101.5 millimeters in females. 



(_/*) O. s. erlangen. — Western and southwestern Ethiopia and 

 northern Kenya Colony to the Upper White Nile district of the 

 Sudan where it meets and merges with jebelensis. Much lighter 

 than hilgerti, the throat not black, but clouded and narrowly barred 

 with black, the ear coverts grctyish white ; wing length 90-103 milli- 

 meters in the males, 80-100 in the females. 



(A;) C. s. leucotis. — Eritrea, Bogosland, and northern Ethiopia 

 (Tigre district), and adjacent parts of the Sudan. Lightest of all 

 the races, throat light gray faintly barred with blackish, cheeks and 

 auriculars white, wings 99-103 millimeters. ^- 



(Z) C. s. Jeucophthalmms. — Savanna region of the northeastern 

 Congo basin, from the Nepoko River northward to the southern 

 border of the Anglo-Egyptian Sudan, and probably extending west- 

 ward along the northern edge of the Congo forest. This bird and 

 the next, nigncoUis, differ from all the other races of Colius striatiis 

 in that they have black foreheads. In the present subspecies the 

 iris is white, the hind neck and upper back are barred with dark 

 brown; wings, 87-96 millimeters in the males, 86-97 millimeters in 

 the females.^^ 



{m) C. s. nigricoUis. — Cameroon to the lower Congo, east to Shari 

 and lower Ubangi Rivers. Similar to leucojjhthalmus but with 

 brown iris, no bars on hind neck and interscapulars; wings, 92-99 

 millimeters (both sexes, as sexes are alike in size). 



In the character of the black forehead the last two races suggest 

 an affinity with castanotiis, but the latter is so very distinct (lower 

 back and rump bright reddish brown) that I follow Sclater and 

 keep it specifically distinct.
