534 Mr. C. Chubb on the Birds of Paraguay. 



I agree with Mr. Oberholser in making this form a sub- 

 species of P.fuscus (Vieill.). P. koeniswaldianus Bertoni can 

 only be regarded as a synonym of the present species, as 

 suggested by Dr. Ihering.

These examples belong to the Brazilian form with the deep 

 chestnut-coloured wings and tail. I can only regard 

 D. tarefero of Bertoni as quite inseparable from this 

 species.
