Beside the species given in the following synopsis, two others are 

 recognized in Gray's Hand List (Nos. 430 and 432). The G.pTia- 

 Icenoides Vieill, seems to be a distinct species, and unlike any other, 

 is said to have a black bill!! Its relations seem to be with G. infus- 

 catum and G. pumilum. It has the crown longitudinally streaked, 

 and the lower parts striped with blackish. The G. ocellatum Homb. 

 and J., said to be from Chile, I have not seen.
