I have examined a considerable number of specimens 

 from Uganda and south-east Africa, and do not consider 

 that the characters said to distinguish this new race are 

 constant. 



Considerable variation takes place in the plumage of the 

 typical form and the feathers wear many shades lighter. 

 Birds from Uganda certainly appear to be generally darker 

 on the upperparts, but when the two series are mixed up it 

 is practically impossible to distinguish the northern from 

 the southern birds. 



The two birds from the Manenguba Mountains are 

 particularly interesting, as they do not belong to the 

 dark-backed race, if such can be recognised, but are quite 

 indistinguishable from specimens from Pinetown in Natal. 

 I have therefore referred the Cameroon birds to S. apicalis. 

 The single example from Angola is similar to the darkest 

 specimens of so-called S. a. brunneiceps, and is much more 

 likely to deserve a subspecific name than any race from 

 East Africa.

Examples of this rare species were oljtained by Alexander 

 on the lower slopes of the Cameroon M ountain. Remarks on 

 this form will be found in my previous paper (Ibis, 1915, 

 p. 502).

Examples of this species in the British Museum have been 

 obtained from the River Ja, Cameroon, Mpanga Forest, 

 Uganda, and Ndalla Tando, northern Angola. 



Reichenow records it from Yaunde (the type-localitj) and 

 Dscha, both in Cameroon.
