Medium sized Furnariide (length about 145-190 mm.) with small, 
roundish, non-operculate nostrils, culmen (from base) shorter than 
tarsus, and basal phalanx of middle toe not wholly united to lateral 
toes. 
Bill much shorter than head, relatively rather deep and compressed, 
its width at loral antiz much less than its depth at same point and 
equal to one-third to much more than one-third the distance from 
nostril to tip of maxilla; culmen (from base) shorter (usually much 
shorter) than tarsus, broadly and rather indistinctly ridged, nearly 
straight for basal half (more or less), more or less strongly decurved 
terminally, the tip of maxilla slightly uncinate or sub-uncinate; 
maxillary tomium straight or very nearly so to near tip, where more
