This species is doubtfully distinct from the Brazilian P. polychropterus, but seems to 
be smaller and to have the white tips to the tail-feathers rather wider and extending 
further along the outer web of the feather. 
It was originally described from a specimen obtained near Santa Marta in Colombia, 
and skins of it occur in the trade collections made in the neighbourhood of Bogota. 
In our country it is much more common in the portion bordering the southern 
continent. Mr. Nutting says’ that it is not common in the deep woods near Sucuya in 
Nicaragua, and we have only seen one or two specimens in native collections made in 
Vera Paz, Guatemala, so that we have no personal acquaintance with the species.
