TURDOIDES LEUCOPYGLA. OMOENSIS (Neumann) 



Figure 9 



Crateropus smithi omoensis Nehjmann, Bull. Brit. Orn. Club, vol. 1-1, p. 15, 1903: 

 Senti River, afl3uent of the Omo, southwestern Ethiopia. 



Specimens collected: 



1 male, 1 female. Loco, Sidarao, Ethiopia, March 15, 1912. 

 1 female, Gidabo River, Ethiopia, March 15, 1912. 



Soft parts : Iris red ; bill black ; feet gray. 



These three specimens, together with Neumann's two "intermedi- 

 ates between lacuum and omoensis'''''^ extend the range of omoensis 

 to the Sidamo district. The present three birds are in no way inter- 

 mediate in their characters but are typical examples of omoensis. 



This race is very slightly smaller (average difference only) than 

 lacuum. The male has the following dimensions: Wing, 110; tail, 

 113; culmen, 21.5; tarsus, 34 mm. Females: Wing 109-113; tail, 

 98-100; culmen, 21.5, 22; tarsus, 33.5, 34 mm. This species appears 

 to decrease in size and to increase in darkness from east to west 

 across its range. 



Nothing has been recorded of its habits other than that it usually 

 goes in small flocks and is noisy. Ogilvie-Grant ^^ writes that speci- 

 mens collected in July in the Gofa and Uba regions were in molt. 



The altitudinal range of omoensis appears to be 4,000 to 7,000 feet. 



TURDOIDES HYPOLEUCA (Cabanis) 



Crateropus hypolencus Cabanis, Journ. fiir Orn., 1878, pp. 205, 226 : Kitui, 

 Ukamba, Kenya Colony. 



SPECaMENS COLLECTED : 



1 male, Big Bend Hill, Thika River, Kenya Colony, August 28, 1912. 

 1 male, betvpeen Thika and Athi Rivers, Kenya Colony, August 29, 1912. 



The Kenya pied babbler is a common bird in the southern parts 

 of Kenya Colony from the Ukamba and South Kenya Provinces 

 through the Kikuyu and Teita districts. Van Someren ^^ writes that 

 its range extends to the coast, but I know of no records nearer the 

 coast than Useguha and Kilimanjaro. In northern Tanganyika Ter- 

 ritory it occurs on the upper stretches of the Pangani River, but not, 

 as far as I know, at the mouth. 



Neumann ^^ has separated the Pangani, Useguha-Kilimanjaro 

 birds under the name rufuensis^ on the basis of paler dorsal colora- 

 tion, the rump and upper tail coverts lighter than the back; the 

 forehead light gray, and the feathers of the upperparts with pale 



sojourn. fUr Orn., 1906, p. 261.
