p. 9). (Type, Tanagra guianensis Gmelin.) 



Large and stoutly built Vireouidge (wing more than 70 mm.), with 

 relativeh^ hdgh and compressed bill (its depth at frontal antiae nearly 

 twice its width at same point), lateral toe (without claw) as long as or 

 longer than hallux (without claw), its claw reaching to decidedly 

 beyond base of middle claw; upper parts olive-greenish, varied by a 

 rufescent superciliary stripe, the under parts with more or less of 

 yellow or olive-yellowish. 



Bill large but relativeh^ short, deep and compressed, the exposed 

 culmen much shorter than tarsus but nearly equal to middle toe with 

 claw, the depth of bill at frontal anti» very much greater than its 

 width at same point but decidedly less than length of gonys; culmen 

 gradually curved for most of its length (sometimes nearlj' straight 

 basally), the curve gradually more decided terminally, the tip of max- 

 illa usually not strongly uncinate; gonys shorter than distance from 

 nostril to tip of maxilla, strongly convex; maxillary tomium straight, 

 or nearly so, distinctly notched subterminally, that of the mandibular 

 tomium faintly notched. Nostril exposed, broadly oval or roundish, 

 in lower anterior portion of nasal fossge. Rictal bristles weak, less 

 strongly developed than those of latero-frontal and chin feathers. 

 Wing rather short and rounded; tenth primary half as long as ninth.
