SP. CHAR. (No. 3,976 ♂.) Above olive-green; the whole top of head and
nape ash-color, the edges of this cap and a loral line dusky, but not
very decidedly so. A grayish-white line from nostrils over the eye.
Beneath white, the sides of the neck, breast, and body bright
olivaceous-yellow; the axillars and crissum rich sulphur-yellow. On
the breast the yellow extends almost to the median line, the color of
opposite sides separated by a narrow interval. Quills dusky-brown;
margined externally, except at ends of primaries, with olive-green,
internally with grayish-white of a decided yellow shade. Tail-feathers
dark olivaceous-brown, bright olive externally, internally
olivaceous-yellow. Iris yellow or “red.”
Bill horn-color, paler below. Legs plumbeous. Wings long and pointed.
Second and third quills nearly equal; fourth a little less; first
about intermediate between fourth and fifth. Total length, 6.00; wing,
3.20; tail, 2.60.
HAB. From northern border of Mexico to Isthmus of Panama, especially
on west side.
This species has not yet been recorded as taken within the limits of
the United States, but it comes so near to our southern border that it
doubtless sometimes crosses the line. Nothing distinctive appears to
be known of its habits.
Vireosylvia philadelphicus, CASSIN.
