Bill very large, much deeper, broader at the base and more hooked than that of Eurylaemus, the upper mandible more overhanging, and with the edge more convex near the gape; but the culmen is comparatively much shorter and more prominent. Rictal bristles replaced by plumules, which are situated in a nude area between the eye and bill. Wings and tail rounded; wing longer than tail. Tarsus distinctly scutellated in front. Sexes alike.
The plumage is mostly black. Only a single species is known.
