Sudanese form in Ibis, 19 19, p. 645, without coniniitting themselves 

 verv niiich ! I certainlv agrée with Grant that Reichenow's race 

 froin Togoland is ol doubtful validitv. The cliief character (black 

 lesser under wing-coverts) is found in an example from Nyasaland 

 in the British Muséum shot alongside others with brown under 

 wing-coverts 1 I would recognise, therefore, onlv three geogra- 

 phical forms, onlv one of which — the tvpical race — occurs in 

 West-Africa. Thèse are : 



I. — Centropus grillii grillii. 



Cf. sii/>ra.
