We find it impossible to follow the characters, which Dr. Sharpe 

 proposed in the ' Catalogue of the Birds in the Collection of the 

 British Museum,' for the separation of the species of this genus. 



Cathartes aura (Linn.) refers to the Xorth American bird, the 

 type locality being Mexico; C. iota Molina, from Chile, becomes 

 available for the Chilian, Argentina, and Falkland Island form. 



We are using C. rujicollis Spis for the Eastern Soutli American 

 form, which ranges from Bahia and Piauhy to Guiana, and propose 

 to add as synonyms, C uralntinga Pelz. and C. pern'iara Sharpe.
