Small Picidse (wing about 80-105 mm.) with outer hind toe longer 

 than outer front toe, tail less than two-thirds as long as wing, inner 

 hind toe relatively very small (the toe and claw together less than 

 half as long as outer toe), back plain olive, olive-russet, orange- 

 russet, or red, no white spots on outer webs of primaries, and under 

 parts plain ohve-brown or olive, or barred with olive or dusky and 

 whitish, or else plain whitish and upper parts red. 



Bill shorter than head, rather stout, about as wide as deep at 

 anterior end of nostril, rather abruptly contracted in width ter- 

 minally, the tip distinctly chisel-shaped; culmen straight or very 

 faintly convex, sharply ridged; gonys decidedly less than twice as 

 long as mandibular rami, nearly straight, or very faintly concave 

 terminally and convex basally, more or less distinctly ridged; supra- 

 nasal ridge and prenasal groove very distinct, parallel with but far 

 removed from culmen, running out to edge of maxilla at a point 

 near or slightly anterior to middle of tomium. Nostril small and 

 narrow, longitudinal, sometimes pointed anteriorly, covered by a 

 distinct prefrontal antrorse tuft of small hair-like, bristle-tipped, 

 feathers. Feathers of malar apex and chin antrorse, bristle- tipped. 

 Orbits mostly feathered. Wing moderate or rather short, the longest 

 primaries exceeding secondaries by much less than one-fourth 

 (usually less than one-fifth) the length of wing; seventh and eighth, 

 sixth and seventh, or fifth, sixth, and seventh primaries longest, 

 the ninth shorter than fourth, the tenth (outermost) a little more 

 than one-fourth to nearly one-half as long as ninth. Tail less than 

 two-thirds (sometimes only half) as long as wing, the middle rectrices 

 gradually and only moderately narrowed, and more or less strongly 

 decurved, terminally. Tarsus nearly to quite as long as outer front 

 toe with claw, decidedly shorter than culmen; outer hind toe de- 

 cidedly longer than outer front toe; inner hind toe relatively very 

 small, the digit and claw combined less than half as long as outer 

 hind toe.
