Medium-sized Formicariidæ (length about 160 mm.) with short, very stout, and strongly hooked bill, rounded and exposed nostrils, and finely barred plumage.
Bill about as long as head or a little shorter, very stout, strongly hooked, its width at frontal antiæ about equal to its depth at same point and about two-thirds the distance from nostril to tip of maxilla; exposed culmen shorter than tarsus, nearly straight to near the abruptly decurved and strongly uncinate tip of maxilla; maxillary tomium straight for most of its length, distinctly notched or concave subterminally; mandible falcate, recurved terminally; gonys strongly convex, ascending terminally, broadly rounded (not ridged) beneath, decidedly longer than unfeathered portion of mandibular rami; mandibular tomium distinctly toothed and notched subterminally. Nostril exposed, small, rounded or broadly oval, with an internal tubercle showing within upper posterior portion. Rictal bristles obvious but small; feathers of chin and anterior portion of malar region with bristly points or terminal setæ. Wing rather short,
