This peculiar form, remarkable for its short, much compressed, 

 and up-turned bill, occurs throughout the Neotropical Region from 

 Mexico to Southern Brazil. The two species here recognized both 

 vary sliglitly in different parts of their ranges, but not, 1 now think, 

 sufficiently to warrant specific distinctions for the local races.
