You/Kj. — S'mii\'Av to the adult female, but wing bars deep bufly and 

 plumag-e of a much looser texture. (Immature males are variously 

 intermediate in coloration between the fully adult male, as described 

 above, and the adult female, two or three vears being probably 

 required for attainment of the full plumage. Some freshly molted 

 adult males, especially those showing traces of immaturity, have the 

 under parts posterior to the black jugular band more or less buffy, 

 sometimes cpiite strongly so. These occur in the same localities as 

 specimens with the same parts pure white.)

^ It is remarkable that while in Mexico and thence to Honduras this species appears 

 to be confined to the Atlantic slope (except in Guatemala and perhaps in Chiapas 

 and Oaxaca) , it appears to skip Nicaragua altogether to reappear in western Costa 

 Rica, where, according to Cherrie (Auk, ix, 1892, 27), it occurs from the valley of 

 San Jos6 to the Pacific coast. If the species occurs anywhere in Nicaragua I have 

 been unable to find any record to that effect.
