and notched subterminally ; gonys distinctly convex, ascending 

 terminally, more strongly convex and rather prominent basally. 

 Nostril exposed, very small, circular, with an oblique tubercle in 

 posterior half. Rictal bristles obvious but small; feathers of chin, 

 lores, and anterior portion of malar region with distinct bristly 

 points. Wing moderate, rather pointed, the primaries decidedly 

 longer than secondaries; sixth and seventh, or sixth, seventh and 

 eighth, primaries longest, the tenth (outermost) shorter, the ninth 

 longer, than secondaries. Tail decidedly shorter than wing to end 

 of secondaries, strongly rounded (graduation about equal to half the 

 length of exposed culmen), the rectrices (12) rather narrow, rounded 

 terminally. Tarsus longer than exposed culmen, less than one- 

 third as long as wing; acrotarsium distinctly scutellate; outer side 

 of planta indistinctly scutellate or with scutella obsolete, the inner 

 side with a single series of rather small roundish or oval scutella; 

 middle toe, with claw, much shorter than tarsus; outer toe, without 

 claw, reaching to beyond middle of subterminal phalanx of middle 

 toe, the inner toe slightly shorter; hallux about as long as inner toe 

 but much stouter; basal phalanx of middle toe wholly united to 

 outer toe, for about half its length to inner toe; claws strongly 

 curved, broad, compressed, that of hallux much shorter than the digit. 



Coloration. — Above plain brown, the wings (sometimes pileum 

 also) more rufescent, the tail chestnut or deep cinnamon-rufous; 

 under parts plain olive-buffy or yellowish, more grayish olive on 

 flanks; adult males with a concealed dorsal patch of ochraceous or 

 tawny. 



Range. — Southern Mexico to Peru. (Monotypic ?)'* 



THAMNISTES ANABATINUS ANABATINUS Sclater and Salvin. 



TAWNY ANTSHRIKE. 



Adult male. — Above plain tawny brown (nearest raw umber or 

 tawny olive), paler on forehead; upper tail-coverts and tail deep 

 cinnamon-rufous or rufous-chestnut; wings (including secondaries) 

 dull cinnamon-rufous or russet; interscapulars light cinnamon-rufous 

 or deep ochraceous-buff beneath surface (forming a large and con- 

 spicuous patch when feathers are spread) followed immediately by 

 a subterminal bar or spot of black; an indistinct superciliary stripe 

 and suborbital area of pale grayish buffy, the two separated pos- 

 teriorly by a postocular streak of brown; auricular region and sides 

 of neck similar in color to back, but paler, the color deepenmg some- 

 what on malar region; general color of under parts pale brownish 

 yellowish anteriorly, more grayish (tending more or less toward 



a Although three species are recognized by authorities, it is Hkely that these may 

 be in reaUty forms of one species. Two of these, however (T. sequatorialis Sclater 

 and T. ru/escens Cabanis), I have not seen.
