Medium sized Furnariidse (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 antic^e 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 curvetl 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 wdth 

 narrow superior membrane. Rictal bristles wanting, and feathers of 

 chin, etc., without terminal setae. Wing moderate to rather long, 

 rather pointed, with longest primaries exceeding secondaries by at 

 least length of gonys; seventh and eighth, sLxth, 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. inirrliodes) to as long as wing (P. rufus) , s\\g\\i\y rounded 

 (P. fuscipennis, P. erythrocercus) to graduated for more than one- 

 fourth its length (P. j)yrrhodes, P. rufus), the rectrices (12) sub- 

 rounded to subacuminate terminally. Tarsus longer than culmen, 

 less than one-fourth as long as wing (P. licJdeiisteini, P. fusci- 

 pennis) to more than one-fourth as long (P. rufus), rather stout,
