Colymbus ruficollis capensis (Salvatlori). 

 A young male in first plumage. Uni Ruulja, KorJofan, 

 Dec. 1920. 



Sylvia riippelli Temminck. 



Sclater and Praed, page 6(J1, are I think in error in 

 supposing the females they describe to be young birds. A 

 large series which we have from Egypt shows that the 

 female of this Warbler never has a black crown. Some, 

 which I take to be really adult, not to say old birds, have a 

 dark grey throat. The usual female plumage mncli re- 

 sembles that of a Lesser Whitethroat but is a little darker. 

 Sometimes a little blackish is apparent on the crown. 



Hypolais pallida pallida (Hemp. & Ehrenb.). 



The ty[)ical form seems to be restricted to Egypt and the 

 Sudan, " Nubia " included. Sclater ai d Praed's statement 

 that it breeds in S.E. Europe and W. Asia is not correct, as 

 the form from those countries is H. p. eUvica. I have one 

 specimen of the latter from Giza, Egypt, in April, and it is 

 possible that it may be found to visit the Sudan in winter. 



Locustella luscinioides luscinioides (Savi). 



I do not know on what authority Shelley based his state- 

 ment that this bird was a resident in Egypt. I have no 

 proof that it is more than a spring and autumn migrant.
