What Elliot has described as the female is certainly a young 

 male. 



It is a common species in Brazil. 



In the Humming Bird , i8gi, vol. i., p. 26, I have mentioned 

 a specimen of my collection agreeing exactly with the 

 description of the adult male ; but it has a very short bill, 

 hardly ^ of an inch long.
