Above dark plumbeous olive ; crown darker, blackish ; wings and 

 tail blackish, the wing-coverts and outer secondaries more or less 

 edged with whitish : beneath dirty white, clearer on the throat and 

 middle of the belly, which latter has sometimes an olivaceous tinge ; 

 bill above blackish, beneath yellowish white ; feet blackish ; first 

 primary shorter than the fifth : whole length 5 - 3 inches, wing 2'9, 

 tail 2-5. Female similar. 



Hah. Mexico and Central America, southwards to Peru and 

 Amazonia. 



It is possible that I may have united more than one species 

 under the present name, which was originally based upon Mexican 

 specimens, but the bird has been subsequently traced down the 

 American continent to Peru and Lower Amazonia. In some cases it 

 is difficult to discriminate between this species and dwarfed or 

 immature examples of C. virens ; but I think that Mr. Ridgway's 

 character of the first primary being shorter than the fifth in C. bra- 

 chytarsus generally holds good.
