I first established this species in 1862 from a Bogota skin 

 in my own collection, which for some years remained unique. 

 In 1871 I succeeded in obtaining a second example from 

 a collection received from Oyapok by Madame Verdey of 

 Paris. Herr v. Pelzeln also recorded in the same year that 

 Natterer obtained examples of this bird on the Rio Negro.
