We find these birds identical with the West African form 

 of C. cisiicola, which again is very close to the typical form 

 from southern Europe, There are other examples in the 

 Museum from Lado {Emin) and from the Lake Chad region 

 {Alexander) , as well as from other localities in West Africa 

 and possibly Uganda, but we find nothing similar from 

 Abyssinia. The seasonal plumage change is not very marked, 

 but the summer birds have the head a dull brown without 

 indication of the striping so characteristic of the winter 

 birds.

This bird and another collected by Mr. W. P. Lowe 

 50 miles south of Goudokoro, 1 March 1913, when with 

 Capt. Cozens, we believe must be identified with the bird 

 described by Heugliu, which is now in the Berlin Museum 

 and inaccessible to us. It is a remarkable bird, not unlike 

 some strongly marked Natal specimens of C. t. terrestris, 

 but more richly coloured — the back blacker and the rump 

 redder. The nape, which is quite unstriped, is a dull reddish 

 brown, contrasting somewhat with the brighter red of the 

 rump. We have only found one bird in the Museum which 

 is at all like it. It is one collected at Riru in Northern 

 Nigeria by Jose Lopez, 4 January, 1912, and presented to 

 the Museum by Capt. Brocklebank. It is slightly larger, 

 the nape and rump are the same bright rufous which is 

 so extended that the black striping of the back is much 

 reduced. 



The wings of the Sudan specimens measure, ^ 47 ram., 

 ? 44 mm., that of the Nigerian bird, sexed a male, 51 mm.
