 birds were collected south of the south end of Lake Rudolf, and it is 

 therefore impossible to be sure of the identity of the birds from the 

 Indunumara Mountains and soutliAvard. The species has not been 

 recorded definitely from the latter group of localities. 



CORVULTUR ALBICOLLIS (Latham) 



Corvtts albicoUi'S Latham, Index ornithologicus, vol. 1, p. 151, 1790 : Africa ; 

 restricted type locality Cape Town {aptid Meinertzhagen, Nov. Zool., vol. 

 33, p. 96, 1926). 



Although no specimens of the white-necked raven were collected, 

 and while Mearns did not particularly differentiate between it and 

 crassirostrk in his field notes, it has been thought entirely possible 

 to identify his records and incorporate them in this report. 



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

 Kenya Colony, Mearns noted two of these birds, and on August 10, 

 at Meru near Mount Kenya, he saw 100. Inasmuch as his last 

 records for crassirostrls were from Gato River near Gardula, March 

 29-May 17, and inasmuch as albicollis is the only species known to 

 occur around Mount Kenya, it seems certain that the above records 

 refer to albicollis.

 Specimens collectted : 



4 males, 3 females, Adis Abeba, Ethiopia, Decemjjer 27, 1911- January 9, 



1912. 

 1 female, "Lake Trip" (=near Lake Stefanie), Ethiopia, March 9, 1912 (C.

The giant thick-billed raven is found in the highlands of Shoa 

 and Arussi-Gallaland, and while commonest at moderate elevations 

 up to 10,000 feet (3,000 meters) it also occurs in the lower areas of 

 adjacent parts of British Somaliland and of the Sudan. Neumann " 

 writes that the region about Lake Rudolf (Rendile and Turkana 

 districts) forms the boundary south of which Cor^vultur crassirostris 

 does not occur and north of which CorvuUur albicollis is unknown.
