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 99 birds. I 
know nothing whatever of its habits.— TV. 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.]
