Supra olivaceo-viridis ; capite alis et cauda nigris ; vitta superciliari longa et' 

 macula auriculari utrinque albis ; subtus pallide cinerascenti-albus, gula alba, 

 crisso ochracescente ; rostro nigro ; pedibus nigro-fuscis. Long, tota T-'i, alae

Mus. Acad. Nat. Sc. Philada. 



Two specimens of this very distinct species of Saltator are in the Academy's 

 collection, one marked " Popayan," the other " Neio Grenada." There is na 

 known bird of the genus to which it shows great resemblance, but I think it 

 may be most naturally arranged near to S. orenocensis.
