BIRDS OF NOBTH AND MIDDLE AMERICA. 



189 



Althoug-h united by Sclater and others to C. flavicrissm Sclater, 

 this bird is nevertheless quite distinct, at least subspecifically. It is 

 decidedly larger than C. flavicrissm,'^ especially the bill, which is much 

 deeper and broader at the base and otherwise diilerent in shape, and 

 the yellow patch on the wing is conspicuously smaller (much less than 

 half as large) in both sexes. Whether the two forms intergrade or not 

 I am unable to state, not having been able to examine specimens from 

 intermediate territory.
