The series examined indicates that at least specimens from southern Honduras, 

 Nicaragua, and Costa Rica require subspecific separation, P. adolphi proper being 

 restricted to the birds from southeastern Mexico. Examples from Guatemala and 

 British Honduras are intermediate, but with the small number of specimens available 

 for comparison I am unable to decide whether they are nearer the typical or the 

 southern form. Costa Rican and other southern birds are darker than those from 

 southeastern Mexico, especially the adult males, which have the throat much darker 

 and the chest much duller in color.
