BIRDS OF ETHIOPIA AlvTD KENYA COLONY 465 



plumag:e. Now, if we examine the criteria given by Berger, or by 

 Zedlitz, we find that the birds are said to combine features, which in 

 darnaudii^ are immature and breeding adult plumage characters. 

 Obviousl}^, individual specimens from Lake Baringo can not be 

 young and old at the same time, and it therefore appears that there 

 may be something to the color characters and hence, to the race liav- 

 ing them. However, until I have an opportunity of examining Lake 

 Baringo material, I prefer to follow Sclater's list as a matter of 

 policy. 



2. T. d. usamh'iro. — From the Southern Guaso Nyiro and the Loita 

 Plains, Kenya Colony, south to the regions south and southwest of 

 Lake Victoria. Tanganyika Territory (east to the Wemberre 

 Steppes). This race is similar to the nominate form but larger 

 (wings 81-87 as against 63-77 millimeters in darnaudii). 



3. T. d. hohm'). — From southern Italian Somaliland, through east- 

 ern Jubaland and eastern Kenya Colony west to the eastern side of 

 the Rift Valley (one record from northwest of Mount Kenia, see 

 Van Someren), south to northeastern Tanganyika Territory (Pare 

 Hills, Kilimanjaro, Nguru Mountain, Arusha, etc.). This form is 

 very distinct in coloration, having the crown solid black, instead 

 of yellow barred or spotted with black, and has a large black throat 

 patch. In size it is nearer to darnaudii than to usamhiro; wings 

 72-80 millimeters. This race is considered a distinct species by some 

 workers, and it may well be. If it should be found breeding north- 

 west of Mount Kenia, where darnaudii (or zedlitzi) probably occurs, 

 then it would have to be granted specific rank. 



4. T. d. em.inl. — Tanganyika Territory, from the Mpapwa, and 

 Ugogo districts, south through the Dodoma, Iringa, and Uhehe 

 country to the north end of Lake Nyasa. This race has the top of 

 the head black as in hoJwii but differs from it in having a broad 

 black band extending from the chin posteriorly over the entire length 

 of the throat. It is also somewhat darker on the back. If hohmi 

 be considered specifically distinct from darnaudii, then emini should 

 be placed as a race of hohmi, not of darnaudii as Sclater has done. 

 Van Someren "^ showed that Claude Grant ^'^ was mistaken when he 

 figured emini as the female of darnaudii. 



The present series of hohmi varies chiefly in the amount and in- 

 tensity of the yellow on the upper abdomen and the amount of orange 

 tinge on the posterior portion of the superciliarics. Tlie size varia- 

 tions are as follows :
