'Jordan «fc Gilbert, Proc. U. S. Nat. Mus. 1880, 28: type Corvina stearnsi Steindach- 

 ner. (Spanish roncador, grunter.) This is perhaps a valid genus, distinguished from 

 Sciwna by its large, paved pharyngeals, resembling those of Pogonias, but not united. 



^ = Corvina Cuvier, Regne Anim. ed. 2, ii, 173, 1829: type Sciwna nigra BIoch= 

 Sciwna umhra L. None of the'speeies of the group called Sciwna by Cuvier were known 

 to Linnaeus.
