Bill about half as long as head or considerably less, narrowl}- siil:)- 

 conical, cojnpressed, its width at frontal antias decidedly less than its 

 depth at same point and equal to less than half the distance from 

 nostril to tip of maxilla; exposed culmen equal to or longer than 

 middle toe without claw, rounded or very indistinctly ridged, gently 

 and evenly convex throughout, the tip of maxilla acute (in lateral 

 view) and not at all uncinate; gonys nearly twice as long as mandibu- 

 lar rami, nearly straight, ascending terminally; maxillary tomium 

 nearly straight (usually more or less deflected terminally), without 

 trace of subterminal notch. Nostril wholly concealed by dense 

 antrorse latero-frontal tufts, small, obliquely oval or almost linear, in 

 lower anterior portion of nasal fossae. Rictal bristles minute (prac- 

 tically obsolete) ; feathers of chin without, but decumbent feathers 

 of lower portion of nasal (latero-frontal) tufts with, bristly points. 

 Wing long and pointed, with longest primaries exceeding outermost 

 secondaries by more than one-third the total length of wing; seventh 

 and eighth, eighth, eighth and ninth, or ninth primaries longest, the 

 tenth (outermost) primary excessively rudimentary, apparently 

 absent, and only to be found by very close examination; tips of 

 secondaries and innermost primaries emarginate; innermost sec- 

 ondaries slightly elongated. Tail equal to or longer than distance 

 from bend of wing to end of outermost secondaries, even or slightly 

 emarginate, the rectrices (except middle pair) not tapering, their 

 tip rather broadly rounded. Tarsus about one-fifth as long as wing, 

 nearly twice as long as middle toe without claw, its scutellation 

 holaspidean, with divisions of acrotarsium distinct, at least on inner 

 side; basal phalanx of middle toe united for greater part to both 

 lateral toes; inner toe, without claw, reaching to or slightly beyond 

 second joint of middle toe, the outer toe very slightly shorter; hallux 

 about equal to inner toe but stouter, its claw longer (sometimes 

 very much longer) than the digit, straight, or very slightly curved; 

 anterior claws slightly curved, often more or less elongated. 



Coloration. — Adult males brownish (more or less pinkish, vina- 

 ceous, or cinnamomeous) above, distinctly streaked only on back, 

 or entirely unstreaked; fore part of crown, elongated horn-like tufts 

 on side of occiput, loral and suborbital regions, and ])atch on chest 

 black; forehead, superciliary stripe, tliroat, and under parts of bodj'^ 

 plain whitish, or except the last (and rarely that also) light yellow; 

 lateral rectrices partly white. Adult females similar but more 

 streaked and with black areas more restricted, duller in color, or 

 broken by streaks. Young; mixed dusky and light brown above (in 

 variably relative amount) speckled or dotted with white or buffy; 

 wing-coverts margined with pale buffy; under parts whitish, the 

 chest more or less tinged with pale brown or buffy and speckled or 

 clouded v/ith dusky
