The only difference that I observe in this series is in the 

 colour of the under tail-coverts, which varies from olive-green 

 to rust-brown ; but there are scarcely two specimens with 

 the same shade of colour, so that this cannot be regarded as a 

 character. The measurements are the same as of others in 

 the National Collection from S.E. Brazil. 



The species is new to the avifauna of Paraguay. 



[This bird is resident but not common, inhabiting the 

 large forests only. — TV. F.~]
