Bill strong, convex, somewhat curved, compressed, almost entire, 
bristly at base; mandibles sub-equal, edges somewhat bent in; nos- . 
trils round, half covered by a membrane; tongue slightly bifid at the 
tip; intermediate between Turdus, Muscicapa, Vireo and Tanagra. 
There is but one species known, Jct. 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.

The genus Quiscatus of Vieillot should find a place between this
