[This species was omitted in * Argentine Ornithology,' 

 but a specimen believed to be from Corrientes, now in the 

 British Museum, was long in my collection, and examples 

 of it were obtained by Natterer and H. H. Smith in Matto 

 Gi'osso, It is probably the Carpintero pardo dorado of Azara.
