thoug^h it wants the emargination on the upper mandible, cannot be 

 more appropriately arranged. 



Bill strong, convex, somewhat curved, compressed, almost entire, 

 bristly at base; mandibles sub-equal, edges somewhat bent inj nos- 

 trils round, half covered by a membrane; tongue slightly bifid at the 

 tipi intermediate between Turdus, Muscicapa, Vireo and Tanagra. 

 There is but one species known, let. dumicola, Vieill. which inhabits 

 the United States (Pipra polyglotta, Wils. I, p. vi, f. 2). It is olive- 

 green, with the throat and breast yellow; belly white; circle round 

 the eyes, and line above them yellow.

 nearly allied to Muscicapa and Sylvia, and ought to be arranged 

 with them.

The genus Quiscalits of Vieillot should find a place between this 

 genus and Caryocatactes. Its characters are as follows:
