Distinguishing characters. — It may be distino;iiished from 

 D. castanea by the inales having a white coUar completely 

 encircling the neck, and bv the females having a deeper chestnut 

 breast, which does not extend well down on to the chest as it does 

 in D. castanea. 



Observation. — The fact that the range of D. castanea and 

 D. horjnop/iora meets on the Togoland-S. Nigérian boundary may 

 account for the spécimen shot by Robin Kemp at Burutu having 

 white feathers at the back of the neck, a character oi D. hoiiiiophora. 

 I hâve referred this spécimen to D. castanea.

There are two races of this bird in Africa, the East African race 

 having been separated on account of the paler coloration of the 

 back of the female. The tvpical bird was described from the 

 Portuguese Congo, and ranges northwards to Sierra Leone. 

 The range of the two forms must meet somewhere in the Belgian 

 Congo, but the birds which Boyd Alexander obtained at Beritio, 

 between Bima and Angu on the Uelle river, and also at Arebi on 

 the Gudima river, appear to be tvpicallv West African examples, 

 as well as the rest of the séries from the Upper Congo. The range 

 of the two races, judging from the material in the British Muséum, 

 seems to be as follows :
