The three names for this s])ecies also were published about 

 the same time, but I believe Vieillot has the priority. It is a 

 very common bird in collections from the Brazils. The I'rince 

 Maximilian of Neuwied met with it frequently during his travels 

 in South-east Brazil^ and gives us the following account of it : — 



" This fine Tamatia I did not meet with so often as the former 

 {Malacoptila torquata). It does not live so near human habita- 

 tions, but is found in the vast thickly-wooded districts, where 

 we obtained many of them. In the summer they live in pairs, in 

 the cold season singly or in flocks. At times pouring forth close 

 to us from among the leafy branches their loud peculiar cry, 

 they astonished the hunters not a little. They are somewhat 

 less stupid and lonely than the former species. I have ofteri 

 seen them in motion, especially when several of them were 

 uttering their loud cries in concert. In their stomachs I found 

 remains of insects. About their nidification I can give no 

 information.''
