Bill horn-coloured above, buff below at base; feet slate- 
coloured ; iris brown. 
The examples enumerated above are identical with the 
series in the British Museum from Brazil. I agree, there¬

Rengerornis leucophthalmus Bertoni is inseparable from the 
present species.

Paraguay, although I never met with it through the southern 
provinces.— W. F 7 .]
