HIRD8 OF NORTH AND MIDDLE AMERICA.

Althouyh united by Sclater and others to C. fiamcrhsim Sclater, 

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

 decidedly larj^er than C. flavwrlssim^ especially the bill, which is much 

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

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

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

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

 intermediate territory.
