The addition of these examples to the British Museum 

 was very welcome, as the exact habitat of the species was 

 previously unknown. 



[This species is one of our very rare "monte" birds. I 

 know nothing whatever of its habits. — W. F]

The amount of white on the secondaries appears to vary 

 a great deal. In this particular individual the dark pattern 

 is the predominating colour, while many others in the 

 British Museum have the secondaries nearly pure white. 



[This species is rare with us here in Paraguay. I have 

 only seen it about half a dozen times in as many years, and 

 know practically nothing of its habits. — W. F]
