Dr. Hartert has recently called attention to the fact that 

 the Black-throated and Black-eared Chats are of one and 

 the same species, of both of which there is a western and an 

 eastern form, and I am thoroughly in agreement with him. 



Hemprich and Ehrenberg's type belonged to the Black-

I obtained examples of both varieties during my stay in

 Examples were obtained during my visit, and specimens 

 received from Mr. Balboni during the summer of 1910 had 

 evidently been breeding. 



All my specimens belong to this form, which is quite 

 separable from S. d. amphileuca, which occurs in *^ Nubia."

I received from Mr. Balboni a male Whinchat shot on 

 April 28th, and another shot on May 15th, 1910, which I take 

 to be a female. The latter was badly damaged by shot and
