Tbis is a widespread species, ranging with but slight 

 variation from the Upper Nile to the Transvaal. Birds from 

 southern Angola and Nyasaland and south of the Zambesi 

 are more olivaceous on the back and more richly rufous 

 below, and may be distinguished as C. h. subrufescens Bocage 

 (P.Z.S. 1869, p. 553: Caconda, Angola). The coast-bird 

 of East Africa is also possibly distinguishable by its richer 

 rufous underparts, but hardly deserves separation.

The Christy birds from Lado and the Bahr el Ghazal are 

 slightly larger and darker coloured ; they also have a wider 

 band of white on the crown. In these respects they approach 

 C. V. melanonota (Cabanis, J. f. O. 1875, p. 235 : Tschint- 

 schoscho, Loango) which ranges north to Uganda. The 

 Roseires birds, on the other hand, appear to be indistin- 

 guishable from the Gold Coast birds which range eastwards 

 along the Welle river, where Alexander procured a good 

 series.
