The description is taken from a female collected on the 

 Ituribisi fiiver in October 1908. 



The young male in its first plumage is very similar to that of 

 the adult female, but differs in having more white on the under 

 surface. The first appearance of the male plumage is marked 

 by the black on the forehead and lores which extends to below 

 the eye. 



The immature bird mentioned above was collected on the 

 Bonasika River in 1912. 



Another young male, which is much more advanced, has 

 nearly attained the full plumage of the adult bird, only a few 

 green feathers on the upper surface and a similar number of 

 white ones on the abdomen remain. 



This specimen was collected on the Ireng River during 

 Mr. McConnoll's expedition to Mount Roraima in October 1898. 



Breeding-season. Unknown in British Guiana.
