from Princes Island with typical examples, it is smaller in size 

 (averaging a little over 6i mm. in tlie wing measurement) but 

 agrées in the pale coloration of the underparts. 



As the West African bird did not appear to hâve a name I 

 described it as C. o. guineensis in the Bulletin of the B. O. C. 

 (Cf. supra). 



The bird from West Africa cannot, in my opinion, be united 

 with Salvadori's Cyanoniitra obscura ragazzii which was descri- 

 bed from Abyssinia. This race is kept separate by ail récent wri- 

 ters : Reichenow, Neumann, Zedlitz, etc. and from an exami- 

 nation of typical Abyssinian birds in the British Muséum they are 

 unquestionably right in doing so. The Abyssinian race is brighter 

 green on the upperparts and has the underparts duskier and strongly 

 washed with yellowish-olive. We hâve, besides, several examples 

 collected by Zaphiro in the Kafla and Jimma districts of S. Abys- 

 sinia, also one ot the typical spécimens from the Turin Muséum 

 from the « Foresta di Fekerie-ghem, Shoa », which shows it to be 

 perfectly distinct from West coast examples. 



The présent species has a wide range in West Africa. It is repre- 

 sented in the British Muséum from Portuguese Guinea, Sierra 

 Leone, Libéria, Gold Coast, Southern Nigeria, Cameroon, Gaboon 

 and Northern Angola; Eastwards it apparently extends through the 

 North Belgian Congo (Boyd Alexander, Mr Carruthers, 

 Dr Christy and others obtained several in the Welle River 

 district) but I am doubtful how far East this West African race 

 extends. 



Whether the spécimens from the South Belgian Congo, Nor- 

 thern Rhodesia and Nyasaland in the British Muséum belong to 

 this form or another race I am undecided. The Nyasaland birds 

 seem to hâve a greener head, and ail hâve a relatively longer bill. 

 We lack spécimens from the type locality of the races described 

 from East Africa to which they will probably prove to belong. 

 Birds from the Mpanga Forest were referred by Ogilvie-Grant 

 (Trans. Zool. Soc, XIX, igio, p. 321) to C. o. ragazzii. Neu- 

 mann has discussed the forms (J. f. O., 1906, p. 249) and more 

 recently Zedlitz (J. f. O., 19 16, p. 76). I am not sure that I agrée
