of B. pallidus, and a new name is required for the northern 

 race, called by Grant B. pallida. This Rothscliild named 

 B. p. sharpei. 



With regard to B. granti Bannerraan (Bull. B. O. C. xxvii. 

 1911, p. 84 : Gibbe river in south Abyssinia), we find that it 

 is founded on what we believe is the summer plumage of a 

 bird indistinguishable in the winter season from B. pallidus 

 of the Sudan. In the Sudan and the low country the bird 

 does not appear to undergo such a marked seasonal change, 

 though there are distinct traces of it. 



Two of the examples from Kamisa collected by Capt. 

 Lynes have a note attached to the ticket stating that they 

 are parent and young and pointing out that the young bird is 

 in the dark plumage of _B. gi'anti, and the old bird is passing 

 from the light plumage of B. pallidus to the darker one of 

 B. granti, though neither of them is as dark as the typical 

 Abyssinian birds become in summer. 



All the adult so-called B. granti were collected in the 

 summer months. 



Whether the stronger seasonal plumage-change of the 

 Abyssinian bird is sufficient to justify its recognition as a 

 separate race we must leave undecided for the present, but 

 we are quite satisfied that the Sudan birds are all the true 

 B. p. pallidus.
