and it is possible to proceed from it as a basis. To work out the races 

 and distribution of this bird requires much greater series than I have 

 been able to examine and I therefore prefer to follow the arrange- 

 ment in Sclater's list" with the exception of recognizing fiowen 

 as a distinct race. It is darker, more grayish on the head, back, 

 and breast than senegalensis, more like the southern form oUvascens 

 but not as dark as the latter. 



If Egyptian birds are taken as typical, as suggested by Grant " 

 then the birds of Ethiopia would have to be known as ellioti Bogda- 

 now. However, the course outlined above seems more in keeping 

 with the facts, both biological and historical, and is the proper one 

 to follow. 



The so-called Uganda race emini seems doubtfully distinct, as it 

 is based on a single female which happened to be pale sandy in 

 color. As maj'^ be noted below, females of the same race vary 

 considerably. 



All 12 specimens are adult. The wing lengths vary from 169 to 

 182 (male); 170.5 to 174 millimeters (female). The two females 

 from Ourso are darker on the abdomen, the blackish bars broader, 

 the reddish brown ones narrower, than in the ones from Wadi Malka 

 and Sadi Malka. The two former are also slightly more tawn}^ 

 above than the latter. 



Along the Ha wash River Mearns found this bird to be very com- 

 mon, January 26 to February 13. He wrote in his field book that, 

 " thousands drink at the Hawash morning and evening, feeding 

 on the open plains. Shy, tough, noisy. In large flocks everywhere."
