Apparently not a common bird in the Sudan. Its range 

 extends to southern Abyssinia and British East Africa, where 

 it intergrades with T. d. massaica. 



Tricholaema melanocephala melanocephala. 



Pogonias melanocephala Cretzschmar in Riippell^s Atlas, 

 1826, p. 41, pi. 28 : Kordofan. 



This species, said to have been obtained by Riippell in 

 Kordofan and Sennar, is not represented by Sudanese 

 examples in the Museum, nor has it been met with by 

 Butler. There is a good series of Abyssinian specimens 

 in the National collection. Possibly Riippell's birds really 

 came from Abyssinia. 



Pogoniulus chrysoconus schubotzi.

We agree with Claude Grant^s revision of this group 

 (Ibis, 1915, pp. 444-447) except that the material before 

 us now extends the range of P. c. schubotzi to the Bahr el 

 Gbazal and confines that of P. c. zedlitzi to the lower 

 White and Blue Niles, if not to Sennar alone. The 

 specimens from the Ubangi river, which Grant referred to 

 the tyjjical form, are, we believe, not that form but 

 P. c. centralis. 



Of the Sudanese forms, P. c. zedlitzi is distinguished 

 from P. c. schubotzi by its slightly paler yellow underside
