pure light grey throat merging into chestnut on the 
breast; buff underparts uniformly 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). 
North-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. :—

Unquestionably all birds in Division 2 are examples of 
Cuculus clamosus ; and before we discuss examples from 
localities in Division 1, I wish to deal with the status and 
plumage of the South African Black Cuckoo.
