The birds from the Bahr el Ghazal show an approach to 

 the typical form from West Africa, and are not so pale 

 as those from Abyssinia and the Blue Nile districts. It is, 

 therefore, unfortunate that Neumann described this form 

 from the Bahr el Ghazal and not from tiie paler Abyssinian 

 bird. 



A young fledgling from Yambio with the tail just sprout- 

 ing resembles the adult in colour, but is paler above and 

 below and the grey of the head not so clear.

It seems very doubtful if it is possible to distinguish 

 any racial forms of the Orange-breasted Bush-Shrike. 

 C. s. similis was considered distinct in Shelley's ' Birds of 

 Africa,^ but even in this case it was remarked that it was not 

 always distinguishable from the West African typical form, 

 and the examination of the very large series now in the 

 British Museum only confirms us in this belief.
