Small, long-legged, roimded-winged Turdidse with wing less than 

 two and a half to nearly three times as long.as tarsus, the latter much 

 more than twice as long as exposed culmen; outermost (tenth) pri- 

 mary decidedly longer than primary coverts, sometimes more than 

 half as long as ninth, the latter never longer than fourth, sometimes 

 not longer than first; upper parts plain brown, olive, gray, or dusky, 

 the head sometimes black; under parts whitish, grayish, or pale 

 brownish, the chest sometimes spotted. 



Bill much shorter than head, variable as to relative thickness; 

 exposed culmen always decidedly less than half as long as tarsus 

 (never longer than outer toe with claw), straight basally, then gradu- 

 ally and increasingly decurved toward tip, sometimes straight for basal 

 half or more; gonys faintly convex, ascending terminally, not shorter 

 than mandibular rami (usually longer); maxillar^^ tomium nearly 

 straight, distinctly notched subterminally. Nostril oval or ovate, 

 overhung by membrane (more or less broad), posteriorly usually in 

 contact with (sometimes partly covered by) feathering of frontal 

 antise. Rictal bristles very distinct; feathers of chin and lores 

 (especially the former) with distinct bristle-like tips. Wing moderate 

 to rather short (less than two and a half to nearly three times as long 

 as tarsus), the longest primaries exceeding longest secondaries by not 

 more than half the length of tarsus, usually much less; outermost 

 (tenth) primary much longer than primary coverts, sometimes much 

 more than half as long as ninth, the latter never longer than fourth, 

 sometimes not longer than first; the seventh and sixth, seventh, 

 sixth, and fifth or sixth longest. Tail decidedly shorter than wing, 

 usually slightly shorter than distance from bend of wing to end of 

 secondaries (longer in ( . occidentalis) , usually slightly rounded (even
