These specimens appear to be quite identical with a series 

 of twenty-one examples in the National Collection from 

 various localities in South America. 



The young bird is distinguished from the adult by the 

 rufous margins to the feathers of the crown and the sulphur 

 or orange bases to the feathers of the head, also by the 

 rufous margins to the upper wing-coverts. 



[This species is resident, but not common. The haunts 

 of these birds are invariably along the forest-streams. I 

 have never seen them in the open, and I know nothing 

 more about their habits. — W. F.]
