 Coropipo o- (emendation) Cabanis and Heine, Mus. Hein., ii, Oct., 1859, 94. 



Small Pipridse (wing about 54-60 mm.) resembling Pipra, but 

 nostril very different (broadly oval or roundish and non-operculate) , 

 tail half as long as wing, and adult males with two or three outer 

 primaries narrow, the tenth (outermost) not longer than second 

 ( shorter than first in one species) . 



Bill less than half as long as head, its depth at nostrils about 

 equal to its width at same point; culmen straight basally, then 

 gradually curved, the tip of maxilla very minutely uncinate; gonys 

 about as long as mandibular rami, faintly convex; maxillary tomium 

 faintly concave, at least anteriorly, minutely notched subterminally. 

 Nostril mostly exposed (though posterior margin covered by bristly 

 plumules of laterofrontal antise), rather large, roundish or broadly 

 oval, without superior operculum. Rictal bristles obvious, but rather 

 small. Wing moderate, with longest primaries exceeding secondaries 

 by more than length of exposed culmen; adult males with two or 

 three outer primaries narrowed for whole length, the seventh longest, 

 sixth and eighth decidedly shorter and equal, ninth intermediate 

 between fifth and sixth, and tenth (outermost) much shorter than 

 first {C. leucorrhoa), or eighth longest, seventh and ninth a little 

 shorter and equal, and tenth equal to fourth {C. gutturalis). Tail 

 half as long as wing or slightly more, even or veiy slightly emargi- 

 nate, the rectrices moderately broad or rather narrow, with rounded 

 or subtruncate tip. Tarsus more than half as long as tail, its cov- 

 ering typically exaspidean; heel joint denuded, except in front and 

 part of sides; middle, toe (with claw) much shorter than tarsus,
