We very much doubt if this is really T. flavigula of 

 Cabanis. We have, however, no specimens from Angola, 

 and as Reichenow states that Angola birds are identical 

 with those from Cameroon, and as our birds are undoubtedly 

 the Cameroon form and not the Uganda form, we are 

 compelled to adopt this name. 



The races of this species appear to be — 



1. P. F. FLAVicoLLis Swains. Senegal to Togoland. 

 Throat bright yellow, underside very dark brown. 



2. P. F. FLAVIGULA Cab. Angola to Cameroon and east- 

 wards to Bahr el (ihazal. 



Throat very pale yellow, underside greyish brown tinged 

 with yellow, lighter in the middle. 



3. P. F. PALLiDiGULA Sharpe. Uganda to Nyasaland and 

 N. Rhodesia. 



Throat pale yellow, but not so pale as in last race, under- 

 side brown strongly washed with olive and yellow, paler in 

 the middle. X.f. shelleyi Neum. J. f. O. 1900, p. .292, is a 

 synonym. 



There are also two birds in the British Museum collection 

 from near Lake Bangweolo which do not agree exactly with 

 this form, but are nearer P. /. flavigula^ only without the 

 paler centre line along the abdomen.

The smaller and paler race of P. scandens to which this 

 bird belongs extends westwards to Cameroon and Northern
