Count Zedlitz is the last Ornithologist to hâve monographed 

 this genus in the J. f. O., pp. 328-345. In so for as the material in 

 the British Muséum allows me, I hâve attempted to follow his 

 déductions and hâve critically examined the West African races 

 of C. griseoviridis. 



Like Count Zedlitz I believe that there are three races of 

 C. griseoviridis between Sénégal and Angola, but I do not entirely 

 agrée with the distribution Count Zedlitz suggests : First, in the 

 extrême North, we hâve in Portuguese Guinea (we hâve no Sene- 

 gambian birds in the British Muséum) a brownish-backed race 

 which apparentlv must be C. g. chrysocnemus, described from 

 Sénégal. This race extends Eastwards, not along the coast, and 

 we find it again at Gambaga in the interior of the Gold Coast, 

 and -further East in Northern Nigeria, where it is still paler brown 

 on the upper parts. Boyd Alexander collected seven of thèse 

 light-backed birds at Gashaga, Mongonu, and Abeshi in Northern 

 Nigeria, and at Kaddai and Yo on Lake Chad, while we hâve 

 other spécimens from Jarko and Shonga in Northern Nigeria of 

 this same pale race. If this race is not chrysooiennis it requires 

 a new name. 



The next race we hâve to deal with is C. g. tincta. Count 

 Zedlitz restricts it to the Guinea Coast from the Niger to Loango. 

 Hère I disagree with him. C. g. tincta is a dark coastal race which 

 I believe extends from Sierra Leone to Gaboon and into the 

 N. Belgian Congo. In Northern Angola occurs the third race 

 which Zedlitz named himself C. g. harterti. Three races of 

 C. griseoviridis in West Africa mav be summarised as follows :
