 Habitat in Brasilia, 



One specimen of this beautiful bird occurs in a fine collection, 

 recently sent to me from the interior of Brazil by Dr. LangsdorlF. 

 This enthusiastic Naturalist is now traversing the inland provinces 

 of that vast empire, by command of the Emperor of Russia. He 

 has done me the honour to request I will publish his Ornithological 

 discoveries ; and the portion he has already sent for that purpose, 

 enables me to say they are very important*
