Pheochroa 4 Goutp, Introd. Troch., oct. ed., 1861, 55. (Type, Trochilus cuviert 
Delattre and Bourcier.) 
Rather large Trochilide (length about 115-120 mm.) with bill 
slightly longer than head, strong, nearly straight, narrowly cuneate 
in vertical profile; wing about three times as long as exposed culmen, 
the outer primary longest, its shaft more or less thickened toward 
base, especially in adult males; tail more than three-fifths as long 
as wing, slightly or moderately rounded, the rectrices rather broad 
but contracted terminally where narrowly rounded; plumage very 
dull—dull metallic bronze-green above, pale dull bronze-greenish on 
anterior under parts, the posterior under parts pale grayish buffy; 
lateral rectrices dull black, broadly tipped with white or whitish. 
Sexes alike in color. 
Bill slightly to decidedly longer than head, stout, nearly straight, 
broader than deep (except terminally), narrowly cuneate in vertical 
profile; tomia smooth; culmen indistinctly ridged (distinctly so 
basally); maxilla and mandible with lateral sulci rather indistinct. 
Nostril narrow, slit-like, overhung by a rather narrow, straight- 
edged (or at least not distinctly convex) operculum, feathered on 
its upper and posterior portions. Tarsus feathered only on upper 
anterior portion, rather stout, slightly shorter than middle and inner 
toes, these equal in length, the outer slightly shorter; hallux slightly 
shorter than anterior toes; middle toe united to outer for whole of 
its basal phalanx, to inner toe for nearly as much; toes and claws 
moderately strong. Wing at least three times as long as exposed 
culmen, the outermost primary longest, its shaft very rigid, more or 
less thickened basally (especially in adult males). Tail more than 
three-fifths as long as wing, slightly to moderately rounded, the 
rectrices rather broad but somewhat abruptly contracted terminally 
into a rounded point. 
Coloration.—Dull bronze-green above, paler dull bronze-green 
anteriorly beneath, with pale dull buffy margins to feathers, the 
abdomen plain dull buffy, the under tail-coverts bronzy grayish, 
margined with white; lateral rectrices black, broadly tipped with 
white or whitish. Sexes alike in color.
