EMBERNAGRA, Lesson. 
Embernagra, Lesson, Traite d’Ornith. 1831. (Agassiz.) Typo Salt a tor viridis, Vieillot. 
Ch.—B ill conical, elongated, compressed ; the upper outline considerably curved, the lower straight; the commissure slightly 
concave, and faintly notched at the end. Tarsi lengthened ; considerably longer than the middle toe. Outer toe a little longer 
than the inner, not reaching quite to the base of the middle claw. Hind toe about as long as the middle without its claw. 
Wings very short, and much rounded ; the tertials nearly equal to the primaries ; the secondaries a little shorter ; the outer 
four primaries much graduated, even the second shorter than any other quill. The tail is moderate, about as long as the wings, 
much graduated ; the feathers rather narrow, linear, and elliptically rounded at the end ; the outer webs more than usually 
broad in proportion to the inner, being more than one-third as wide. The upper parts are olive green, the under whitish. 
Tlie position of this genus is a matter of considerable uncertainty. On some accounts it 
would be better placed among the Spizinae. 
EMBERNAGRA RUFIVIRGATA, Lawrence. 
Embernagra rufivirguta, Lawrence, Ann. N. Y. Lyc. V, May, 1851, 112; pi. v, f. 2. Texas.— Sclater, Pr. Zool. 
Soc. 1856, 306. 
Sp. Ch.—A bove uniform olivaceous green. Sides of the hood, and a stripe behind the eye, dull brownish rufous, not very 
conspicuous ; an ashy superciliary stripe rather yellowish anteriorly. Under parts brownish white, tinged with yellowish 
posteriorly, and with olivaceous on the sides ; white in the middle of the belly. Edge of wing, under coverts, and axillaries, 
bright yellow. Length, 5.50 ; wing, 2.60; tail, 2.70. 
Hah. —Valley of the Rio Grande, and probably of Gila, southward ; Mazatlan, Mexico. 
In this species the bill is rather long ; the wings are very short, and much rounded ; the 
tertials equal to the primaries ; the secondaries rather shorter ; the first quill is .65 of an inch 
shorter than the seventh, which is longest. The tail is short; the lateral feathers much grad¬ 
uated ; the outer half an inch shorter than the middle. 
A specimen of this species from Mazatlan, in the collection of the Philadelphia Academy, 
has the bill rather stouter at the base, and the stripes on the head much better defined. Those 
on the crown are continued, though less distinctly, down the hack of the neck to the upper part 
of the hack. This is probably a male, and No. 6246 a female.
