1921.] collected in Southern Cameroon. 91 



pure light grey throat merging into chestnut on the 

 breast ; buff underparts uiiiformly banded with black ; 

 uniform buff under tail-coverts sometimes bearing a 

 few dark spots or irregular bars, but more often 

 entirely wanting in this respect. 



The range of this Cuckoo seems to be Africa generally. 

 In the British Museum we have specimens from : 



South Africa (Cape Colony^ Transvaal, Natal, Zululand). 



East Africa (Portuguese E. Africa, British E, Africa, 

 Abyssinia). 



No7-th- Central Africa (Sudan^ Niam-Niam country, and 

 north Belgian Congo). 



West Africa (Portuguese Guinea^ Gold Coast^ Cameroon, 

 Congo River, Angola). 



CucuLus cLAMOsus and Cuculus jacksoni. 



Thanks to Lord Rothschild, Sir Frederick Jackson, and 

 Dr. van Someren, who have most kindly lent me all their 

 specimens for comparison with the large series in the 

 Natural History Museum, I have had ninety examples of 

 Cuculus clamosus and Cuculus jacksoni from which to make 

 my deductions, i. e. : — 



Div. 1. 



M8 birds from Uganda, Brit. E. Africa, Equat. 



I Great Lakes, S.E. Ethiopia, S. Abyssinia. 



j 12 birils from the Gold Coast, Sierra Leone, 



l^ N. Angola. 



( 10 birds from Nyasaland. 

 -p^. jj I 20 l)irds from Cape Colony, Natal, Zambesi, 

 I Bechuanaland, Damaraland, Transvaal, South 



i^ Rhodesia. 



Unquestionably all birds in Division 2 are examples of 

 Cuculus clamosus ; and before we discuss examples from 

 localities in Division 1, 1 wish to deal with the status and 

 plumage of the South African Black Cuckoo.
