264 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 o£ 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]
