Bill moderate in size, the culmen (chord, from extreme base) less than half to half as long as tarsus, its depth at base greater than distance from anterior end of nasal fossa to tip of maxilla, its width at rictus equal to or greater than its depth at same point; culmen strongly con- vex, more or less distinctly ridged, especially toward base. Outermost primary usually longer than eighth (from outside) (shorter than eighth in subgenus Eupsychortyx), the third, fourth, and fifth (from outside) longest, the second and sixth but little shorter.

Tarsus a little less than one-third as long as wing, shorter than middle toe with claw; planta tarsi covered with small hexagonal scutella, those along posterior edge of outer side larger (more or less) and forming a nearly to quite con- tinuous row. Phwiage and coloration.—Feathers of crown somewhat, to distinctly, elongated either forming or not a distinct crest when not erected. Upperparts mixed gray and cinnamon-rufous, vermiculated with darker, the posterior scapulars, tertials, and rump (especially upper portion) blotched or irregularly spotted with black, the upper tail coverts and median rectrices with shaft streaks of the same, the inner webs of tertials broadly edged with buff; underparts largely white variously marked with black and cinnamon-rufous, sometimes plain cinnamon-rufous; head striped with black and white, but sometimes mostly black, in males, bufif replacing white in femal
