200 REVIEW OF AMERICAN BIRDS. [PART I. 
ing the orange). Under parts, including tibra, lores, and cheeks below the eye, 
bright golden-yellow, the jugulum, breast, and sides streaked with brownish- 
orange; crissum plain. Wing feathers dark brown, broadly margined ex- 
ternally with the color of the back, of nearly the same‘ tint on the edges of 
the primaries, but considerably more yellowish towards the edges of the greater 
and middle coverts and secondaries. All *he quills edged internally (and the 
alula externally) and sharply with sulphur-yellow, like the lining of the 
wings, but not reaching the shaft of the feather—being cut off even at the 
base of the feather by a very narrow portion of the ground color. Tail feathers 
dark greenish-brown, becoming darker centrally, the outer edges like the 
back; the shafts black above, white beneath, the inner webs (except in the 
two central) bright yellow, except at the tips—the yellow not quite reaching 
the shaft on the fourth feather, and extending only half way to it on the fifth. 
In specimens of less perfect plumage the shafts of all the feathers are margined 
internally with the color of the outer webs, this widening on the more anterior 
feather. 
The female (and perhaps autumnal male) differs in a more restricted amount 
or entire deficiency of the brownish-orange oi the crown, and the more obsolete 
stripes beneath, as well as to some extent in the markings of the tail as above 
described. Young birds have the throat and chin creamy white, the nuchal 
region and the sides of head and neck strongly tinged with light ash. The 
other characters appear much as described. 
The wings in this bird are rather short, and much rounded ; the 3d quill is 
longest ; the 4th a little shorter than the 2d; the lst is intermediate between 
the 5th and 6th, very rarely equal to, still less frequently a little longer than 
the 5th, perhaps never exceeding the 4th. In eight specimens the succession 
of length of the quills is expressed by the formula 3. 4. 2.5.1.6; in two, 
3. 4. 2.1.5.6. The tail is considerably rounded. 
Total length, 4.90; wing, 2.62; tail, 2.30, its graduation .15; difference 
between Ist and 3d primaries, .22; bill from forehead, .50, from nostril, .32, 
along gape, .60; tarsus, .80. 
This species, though very similar in external appearance to D. 
zstiva, may be readily distinguished on comparison. It is a rather 
larger bird, with much (disproportionately) broader quills and tail 
feathers. Thus the greatest width of the outer primary is .31, in- 
stead of .25 to .27. A difference in the proportion of the quills is 
constant. As stated, the 3d quill is generally longest in pefechia ; 
the Ist generally shorter than the 5th, always shorter than the 4th. 
In estiva the wing is much more pointed; the Ist quill is about 
equal to the 2d and 3d, rarely a little shorter ; more frequently longer, 
and .25 or more longer than the 5th, instead of being less ; and very 
nearly equal to the 3d, not .20 shorter. 
The differences in coloration consist in the more greenish tinge of 
the upper parts in petechia; the edges of the quills greenish-yellow, 
especially the outer primaries, not almost pure yellow. The yellow 
of the inner webs of the tail feather, in very perfect specimens, only
