•> I can find no constant characters by which birds from Colombia may be 

 separated from those from Guiana and Trinidad. Nevertheless it is possible that 

 a larger series may prove the Colombian bird to represent a slightly diflEerent local 

 race (c/. Chapman, I.e.). 



" Anthoscenus longirostris pallidiceps (Gould) : Differs in having the crown clearer 

 and paler green (less bluish) and throat more rosy and less of a violet tinge.
