that had been built on the side of a tree, in the month 

 of November 1904. As this is one of the most difficult of 

 all birds to skin, the collector feels rather sorry than other- 

 wise when a specimen is met -with ; the skin is about as 

 tough as wet tissue paper, and the feathers fall out in large 

 clusters at the slightest touch. As may be imagined, the 

 patience of the collector is tried to the utmost before the 

 specimen can be put on one side as a good skin. — W. F.~\

Bill, lower mandible orange-yellow ; feet pale slate- 

 coloured ; iris brown. 



This species does not appear to have been previously 

 recorded from Paraguay, though known from Argentina. 

 I have compared the specimen with others from North 

 America and find it to be identical both in measurements 

 and colour of plumage. It is fully adult and is moulting 

 its primary-quills and tail-feathers. 



[A rare species with us here, inhabiting the large forests. 

 I cannot say with certainty whether it is resident or not.
