Dendrocopus rufus Vieillot.) 
Medium sized Furnariide (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 antie 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 sete. Wing moderate to rather long, 
rather pointed, with longest primaries exceeding secondaries by at 
least length of gonys; seventh and eighth, sixth, seventh, andeighth, 
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. fuscipenms, P. erythrocercus) to graduated for more than one- 
fourth its length (P. pyrrhodes, P. rufus), the rectrices (12) sub- 
rounded to subacuminate terminally. Tarsus longer than culmen, 
less than one-fourth as long as wing (P. lichtensteim, P. fusci- 
pennis) to more than one-fourth as long (P. rufus), rather stout,
