Medium sized Furnariidæ (length about 145-190 mm.) with bill much shorter than head (culmen shorter than tarsus), basal phalanx of middle toe wholly united to lateral toes, and plain (unstreaked) plumage.

Bill much shorter than head, moderately compressed, its width at loral antiæ decidedly less than its depth at same point and equal to slightly less to much more than one-third the distance from nostril to tip of maxilla; culmen slightly to distinctly ridged, usually more or less strongly curved from near base, sometimes (P. rufus) nearly straight to near tip, where abruptly decurved, the tip of maxilla minutely uncinate; tomia straight or nearly so for most of their length, usually more or less (but, except in P. rufus, always slightly) decurved distally, without trace of subterminal notch; gonys nearly to quite straight, ascending terminally, slightly convex and prominent basally. Nostril exposed, posteriorly in contact with loral feathering, small, longitudinally oval, nonoperculate or with narrow superior membrane. Rictal bristles wanting, and feathers of chin, etc., without terminal setæ. Wing moderate to rather long, rather pointed, with longest primaries exceeding secondaries by at least length of gonys; seventh and eighth, sixth, seventh, and eighth, or sixth and seventh, primaries longest, the tenth (outermost) about three-fourths as long as the longest, the ninth equal to or longer than fifth and much longer than secondaries. Tail three-fourths as long as wing (P. pyrrhodes) to as long as wing (P. rufus), slightly rounded (P. fuscipennis, P. erythrocercus) to graduated for more than one- fourth its length (P. pyrrhodes, P. rufus), the rectrices (12) subrounded to subacuminate terminally. Tarsus longer than culmen, less than one-fourth as long as wing (P. lichtensteini, P. fuscipennis) to more than one-fourth as long (P. rufus), rather stout,
