Very large Formicariidæ (length about 160-180 mm.) with excessively short tail (shorter than commissure, only one-third as long as the short, much-rounded wing), stout, distinctly uncinate, bill, very long tarsi (half as long as wing), and conspicuously variegated coloration.

Bill nearly as long as head, stout, rather broad and slightly depressed basally, its width at loral antiæ much greater than its height at same point and equal to half the distance from nostril to tip of maxilla, or slightly more; culmen distinctly but not sharply ridged, slightly curved from near base to near tip, where more strongly decurved, the tip of maxilla strongly uncinate; maxillary tomium straight or very faintly concave, distinctly notched subterminally; mandibular tomium faintly convex, slightly but distinctly notched subterminally; gonys strongly convex and prominent basally, nearly straight for most of its length, ascending terminally, the tip of the mandible forming an obtuse, slightly recurved, point. Nostril exposed, posteriorly in contact with loral feathering, longitudinally oval, with a thin, pointed, internal tubercle or splint in upper posterior portion. Rictal bristles present but short and inconspicuous. Wing rather short, much rounded, the longest primaries scarcely if at all extending beyond secondaries; fifth and sixth, or fourth, fifth, and sixth, primaries longest, the tenth (outermost) less than two-thirds as long as the longest, the ninth much shorter than secondaries. Tail excessively short, shorter than commissure, only one-third as long as wing, the rectrices relatively broad. Tarsus much longer than commissure, half as long as wing, stout, rounded posteriorly, distinctly scutellate, the plantar scutella indistinct (fused on upper half or more); middle toe, with claw, about three-fourths as long as tarsus ; outer toe, without claw, reaching to a little beyond subterminal articulation of middle
