The woods bordering the eastern sides of the Andes in Peru and Ecuador are the localities inhabited by 
this fine species, which differs from all its congeners in the black colouring of its throat and in the 
strongly contrasted markings of its hill. It is a rare bird in the collections of Europe ; hut fine examples 
form part of the Royal Museum at Berlin, and in that of the late Earl of Derby; and were also contained 
in the collection of Prince Massena at Paris, now removed to Philadelphia in North America. The spe¬ 
cimens from which my figures were taken were procured by the celebrated traveller Dr. Tschudi during 
his researches in Peru. 
The figures are of the natural size.
