BIRDS OF ETHIOPIA AND KENYA COLONY 79 



3'ika Territory. Loveridge collected specimens in northern Tangan- 

 yika Territory (Morogoro and Kilosa), which in no way approach 

 sphevurus, but are typical poJysonoides. The race sphenurus is not 

 mentioned by either Swann or Sclater as occurring in Ethiopia, 

 which country must be added to the range of this race on the basis 

 of the five specimens collected by Mearns. 



The Frick expedition field party observed this hawk in the follow- 

 ing places: Aletta, March 7-13, 1 seen; Loco, Gidabo Eiver, March 

 15-17, 1 noted; Abaya Lakes, March 18-26, 13 birds; Gato River,

 2 birds ; Malata, June 22, 2 ; Chaffa villages, June 23-24, 3 seen ; Lake 

 Rudolf and the country to the southeast, July 5-10, 4 birds; the 

 plains at the base and south of the Endoto Mountains, July 21-24, 

 2 birds; 27 miles south of Malele, July 29, 2 seen ; the Northern Guaso

ASTUR TACHIRO UNDULIVENTER (Ruppell) 



Falco (Astur) tinduUventer Ruppell, N. Wirbelth., Vog., p. 40, 1836 : Simieu, 

 Ethiopia. 



Specimens collected: 



Female adult, Ankober, Ethiopia, January 22, 1912. 



Unfortunately the present specimen is the only example of this 

 race that I have been able to examine. It is somewhat larger than 

 the measurements given by Swann," who apparently had measured 

 only one female (with a wing length of 215 millimeters.) The pres- 

 ent bird has a wing length of 224 millimeters, tail 201 millimeters, 

 and culmen (from cere) 16.5 millimeters. 



Zedlitz ''^ records a female with a wing length of 220 millimeters, 

 which also exceeds Swann's bird. 



It seems that there are four recognizable races of this hawk in 

 A f rica, as follows : 



1. Astur tachiro tachiro. — South Africa. 



2. Astur tachiro sparsimfasciatus. — Zanzibar, Tanganyika Terri- 

 tory, Kenya Colony, Uganda, Rhodesia, and Angola. 



3. Astur tachiro macroscelides. — West Africa (Gold Coast, south- 

 ern Nigeria to Sierra Leone). 



4. Astur tachiro unduliventer. — Ethiopia.
