COSSYPHA SEMIRUFA INTERCEDENS (Cabanis)

Ukaniba, Kenya Colony. 

 Specimens coixected: 



2 immature males, Meru Forest, Kenya Colony, August 10, 1912. 



1 immature male, Tharaka district, Kenya Colony, August 12, 1912, 



The characters and range of this race have already been given and 

 need not be repeated here. The present three birds are all molting 

 into adult plumage. The Tharaka bird is almost finished molting 

 and is practically adult in appearance; the other two still have a 

 number of juvenal upper wing coverts and crown and abdominal 

 feathers left. 



COSSYPHA CAFFRA lOLAEMA Reichenow 



Cossypha caffra iolacma Eeichenow, Orn. Monatsb., vol. 8, p. 5, 1900: East 



Africa ; Mount Kilimanjaro. 

 Specimens collected: 1 adult male, 1 immature male. Escarpment, 7,300 feet, 



Kenya Colony, September 8-10, 1912. 



Cossypha caffra mawensis Neumann ^ is a synonym. This form is 

 said to differ from iolaenia in having the head and upper back black- 

 ish brown. I have examined some 30 birds from the highlands of 

 south-central Kenya Colony and 5 from Kilimanjaro, and find no 

 difference between them. Lonnberg ^ procured specimens at Escarp- 

 ment, Fort Hall, and Punda Melia, and noted that they were 

 "* * * similar inter se but somewhat darker than a specimen from 

 Kilimanjaro, and have especially less white on the lower side than 

 the latter." The present adult male from Escarpment is exactly 

 like Kilimanjaro birds below, and is slightly paler above than two 

 individuals of typical iolaema. 



Gyldenstolpe ^ suggests that not only is maioensis a synonym of 

 iolaema but that the latter is identical with typical South African 

 caffra, although he uses the name iolaema for his birds from the Kivu 

 district. I have seen 11 South African birds (Cape of Good Hope, 

 Grahamstown, Transvaal, and Natal) and fiind that they are paler, 

 less slaty, more olivaceous and rusty above than iolaema. The south- 

 western form namaquensis I have not seen. Finally, to bring this 

 summary to a close, van Someren "* suggests that bfrds from Kagera
