This rare species was discovered by Bartlett in Peru, and 

 it was dedicated to him, by John Gould. 



My specimens were collected in Peru, by Garlepp in 1887. 



It is very closely allied to H. lactea, from which it differs 

 only by the lighter bronze colour of its general plumage, and 

 the bill, which is longer.
