Adult male. Upper surface shining green, considerably darker 

 on the crown ; upper tail-coverts edged with dirty white ; under 

 surface rufous-brown, darker on the throat, sides of the neck, and 

 flanks ; central rectrices shining green, remainder chestnut, tipped 

 with white and with a wide subterminal black band ; the edge of 

 the outer web of the outermost rectrix also black ; maxilla black ; 

 mandible flesh-colour, the tip black. Total length about 5 inches, 

 wing 2-5, tail 1'5, bill 1-35. 



Female. Like the male, rather smaller : the bill slightly more 

 curved; the under surface paler, more rufous, and with a maxillary 

 stripe of pale rufous. 



Great variation exists in the colour of the plumage of this 

 species, chiefly affecting the width of the subterminal black band of 

 the lateral rectrices, this band being very wide in young birds, 

 nearly evanescent in old ones ; moreover, the tips of the rectrices 

 are much more pointed in young than in old birds. 



Hah. Costa Eica and Panama, southwards to South-eastern 

 Brazil, Grenada, Trinidad, and Guiana.
