The Alta Mira specimen is very pale, agreeing closely in coloration with C. m. 

 palloris; but its measurements are much too small for that form. 



Not having specimens of true C. minor for comparison, I am not at all sure that the 

 birds from the Caribbean and Gulf coasts of Central America and Mexico are really 

 referable to that form. The specimens examined from Yucatan, Honduras, etc., 

 closely resemble in coloration C. m. rileyi of Antigua and Barbuda, but have the whole 

 chest, foreneck, throat, and subauricular and submalar regions clear buff, nearly 

 concolor with the rest of under parts, instead of being more or less distinctly paler and 

 tinged with pale grayish. 



6 Specimens from these localities examined by me. 



* As remarked above, the specimen from Alta Mira is very pale, hardly different 

 in fact from C. m. palloris in coloration, but much too small for that form. The 

 example from Matamoros is deeply colored.
