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 ?)*

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 deepening some- 
what on malar region; general color of under parts pale brownish 
yellowish anteriorly, more grayish (tending more or less toward 
@ Although three species are recognized by authorities, it is likely that these may 
be in reality forms of one species. Two of these, however(T. xquatorialis Sclater 
and T. rufescens Cabanis), I have not seen.
