adult of both races of the Yellow-billed Kite by its black 

 bill. The adult Black Kite is also distinguished from the 

 young of the two yellow-billed races, which also have a black 

 bill, by its whiter head combined with red-brown adult 

 plumage. We should not like to give any distinctions 

 between the young of all three races.

We have no evidence that the true Egyptian Kite ever 

 occurs in the Sudan. It is distinguished from the common 

 Kite of the Sudan, generally called " Egyptian/^ by its 

 lighter, more reddish, colour and paler head ; the tail also 

 is usually a good deal more reddish. We agree with 

 Hartert in treating the Yellow-billed Kites as subspecies of 

 M. migrans. We include this species in our list as there is 

 ill the Museum collection an example from Kenia in British 

 East Africa, which we cannot separate from the Egyptian 

 form, and also because we have no Kites from the north 

 of the Sudan and cannot therefore say where the dividing 

 line between this race and the next comes.

From an examination of the Kites in the Museum collec- 

 tion, it is evident to us that tlie South African Kite ranges 

 throughout Africa to Abyssinia, the Sudan, and north-west 

 Africa to the Gold Coast and Gambia. Birds from Somali- 

 land and south Arabia are almost exactly intermediate 

 between this forai and the last.
