We are not certain to which race of A. capensis these 

 birds should be assigned. According to all precepts we 

 should expect them to be nearer the South African than the 

 northern form. As a matter of fact they are certainly nearer 

 the latter, being distinctly redder and less grey than South 

 African examples. They agree well with a series of five, 

 collected by Alexander near Lake Chad, a single example 

 from Nyasaland, and four from various localities in East 

 Africa. As apparently the sole difl'ereuce between A. c. 

 capensis and A. c. tingitanus is one of a slight tinge of 

 colour, we should not like to say without a great deal more 

 material where one ended and the other began.

There are two specimens of this desert form of B. asca- 

 laphus in the Museum, one from Sliendi (Rothschild and 

 WoUaston), and one from Jebel um Durragh in Kordofan, 

 collected by Dunn. There is also in the Tring Museum a 

 specimen from Shendi, and all three birds are unmistakably 

 the pale form. Whether B. a. ascalaphus also occurs we 

 cannot tell.
