Mr. Charles Chubb on the 
Bill horn-coloured, paler at base of lower mandible; tarsi 
and feet slate-coloured ; iris reddish brown. 
This bird seems to be somewhat scarce in Paraguay and 
was not, apparently, known to Azara. 
[This species is met with occasionally in pairs or in small 
groups of from four to six individuals, but is nowhere com¬ 
mon throughout Central Paraguay; it is essentially a forest- 
loving bird, and I have never seen it on open lands.— W. F.]
