Spécimens iVom Northern Angola I hâve separated nnder the 

 name .Vigrita canicapilla angolensis. 



I also consider Sharpe's Nigrita schistacea and Nigrita emiliae 

 also Reichenow's A^. sparsiinguttata (if this form is distinct from 

 schistacea] as subspecies of A^. canicapilla. 



We schall therefore hâve the Ibllowing races of this bird :

 jet-black, back of crown grey, saparated from forehead and cheeks

 grey on rnmp; wings and tails black; numerous large white spots 

 on wing-coverts ; bill 13. mm.
