between the true ncevius and the present bird ; and the Prince 

 Maximilian of Neuwied has described it with his usual accu- 

 racy under the title of nigricans, and gives a lively account 

 of its habits. He says it is one of the commonest of the whole 

 family in Brazil.

Hab. North Brazil, Para (Mus. Brit.) 



A pair of birds of this species in the British Museum were 

 received from Para, and I have a male in my own collection 

 which I believe to be from the same locality. It differs from 

 the Th. ncevius and its near affinities in the much larger size, 

 stouter bill, and black throat. The quills are brownish-black, 

 narrowly margined exteriorly with white. The upper and un- 

 der tail-coverts are partly tipped with white.
