Pteroglossus castanotis. Gould, Proceedings of the Zool. Soc., Parti, p. 119. 
It Is not a little remarkable that in a group of birds so limited as the present, so many species, hitherto 
undescribed, should reward the researches which the Monograph has called me to institute. I here introduce 
another new species to the notice of the scientific, which approaches in its general form and colours to the 
Pteroglossus Aragari. It is but recently that I became possessed of this fine species, a notice of which, 
together with its specific characters, will be found in the “ Proceedings of the Zoological Society,” Part I. p. 119, 
Its habitat is Brazil, and I would again remark, that if in a country like that, which has been well explored, 
new species are continually discovered to reward the researches of science, how much more may we not expect 
from a laborious scrutiny of those countries of the New World not yet visited by the scientific laboux'er! 
Although I have designated this bird castanotis, a title which clearly indicated the bird in my possession, yet 
on examining a specimen of the same species in the Royal Museum of Paris, I found the chestnut, which 
covers the ears only in my specimen, extending round the throat; but whether this difference is the result of 
age, sex, or season, the limited knowledge I have of the species does not enable me to determine. The Paris 
specimen had the name of P. Utorquatus attached to the pedestal on which it was mounted ; but the true 
P. Utorquatus, for which this bird appeared to have been mistaken, ivas not in the collection.
