BIRDS OF ETHIOPIA AND KENYA COLONY 323 



tipped with whitish giving that region a clouded appearance, breast 

 lightly, but distinctly barred, wings, 93-96 millimeters in the males, 

 86-93 millimeters in the females. 



(e) C. s. movibassicus. — The coastal districts of Kenya Colony 

 from Mombasa (inland to Voi), north to southern Italian Somali- 

 land. Nearest to G. s. afjinis but more grayish on the head, neclc, 

 and interscapulars; the nape and mantle more widely barred (that 

 is the dark bars more widely spaced ) ; the cheeks whiter ; the breast 

 and abdomen slightly darker; wings, 91-93 millimeters in males, 

 86-97 millimeters in females. 



(/) C. s. kikuyuetisis. — The Uhehe, Tabora, Mwanza, and Ikoma 

 districts of Tanganyika Territory north to Kavirondo, Loita Plains, 

 and Ukaniba districts of Kenya Colony east to Mount Kenia, north 

 to Marsabit and the country south of Lake Rudolf. Differs from 

 mombassicus in having darker cheeks and throat blackish with gray 

 tips to the feathers, auriculars silver gray, mantle darker, faintly 

 barred, and larger, wing, 100-107 millimeters in the males, 95-105 

 millimeters in the females. 



{g) C. s. jehelensis. — Uganda (north to Gondokoro) and north- 

 eastern Ruanda. Similar to kikuyuensis but slightly lighter, size 

 smaller, wings, 96-104 millimeters in the male, 93-100 millimeters 

 in the female. This race is only an average one in its characters, 

 although Hartert -® writes that the series in Tring, " * * * shows 

 that kikuyuensis is a much darker form * * *." This is the race 

 that is currently known as ii^gandensls Van Someren,^^ but it is in- 

 distinguishable from the type and paratypes of jeheleiisis. The 

 reason for the general confusion about jehelensis (which is usually 

 considered a synonym of erlangeri) is that the type came from an 

 intermediate locality (Gondokoro) where erlangeri occurs more fre- 

 quently, if anything, than jehelensis itself. Consequently, if a person 

 to whom the type were not available were to examine a small series 

 from Gondokoro he would quite naturally conclude that the birds 

 were probably erlangeri and sink jehelensis into synonymy. How- 

 ever, in the original description of the latter, Mearns ^^ wrote that 

 the throat is black, each feather with a whitish terminal spot, while 

 in erlangeri the throat is certainly not black but merely clouded and 

 narrowly transversely barred with blackish. Another thing that 

 has caused confusion with regard to this form is that Mearns com- 

 pared it with herlepschi, but his series of the latter are not herlepschi 

 at all, but kikuyuensis. 



(h) 0. s. kiwuensis. — The Kivu district of the Belgian Congo, 

 south along the west shore of Lake Tanganyika to about Albert vi lie,
