THE GRAY-CHEEKED FINCH.

_Leucosticte campestris_, BAIRD, COOPER, Orn. Cal. 1, 163, 1870.

SP. CHAR. Body light chocolate-brown, the feathers edged with paler,

those of the back with rather darker centres. Feathers of anal region,

flanks behind, crissum, rump, and upper tail-coverts, wing-coverts,

and primary quills, edged with rose-red; secondary quills and

tail-feathers with pale fulvous; little or no trace of rose on under

wings. Forehead and patch on crown blackish; the hind head to nape,

cheeks immediately under the eye (but not including the auriculars,

except, perhaps, the most anterior) and base of lower mandible all

round, ashy-gray. Throat dusky. Bill yellowish, with dusky tip. Legs

dusky.

No. 41,527, near Denver City, Col., January, 1862 (DR. C. WERNIGK).

Length, 7.00; wing, 4.00; tail, 3.00; exposed portion of first

primary, 3.10. Bill from forehead, .60; from nostril, .40; tarsus,

.75; middle toe and claw, .80; claw alone .24; hind toe and claw, .80;

claw alone, .37.

HAB. Colorado Territory (DR. WERNIGK); Wyoming Territory (MR. H. R.

DURKEE).

This form bears a close resemblance to _L. tephrocotis_, and may,

indeed, be a variety of it; but as it differs in the characters that

appear generally to be those most constant in _Leucosticte_, and as,

in fifty skins of the _tephrocotis_ from one locality, we have seen

nothing like it, we are inclined to consider them distinct. The size

and general appearance are much the same, the difference being that in

_tephrocotis_ the whole cheeks are chocolate below the level of the

eye, the chin without any gray; while in _campestris_ the sides of

head below the eye, but not including the ears, with a narrow border

of the chin, are of this color.

From _littoralis_ this form may be distinguished by the less extent of

ash on the cheeks, which in _littoralis_ covers the whole ears, and

extends back farther on the head all round. _L. griseinucha_ is marked

like _littoralis_, and is much larger than either. Possibly it may be

well to entertain the idea of its being a hybrid between _tephrocotis_

and _littoralis_ or _griseinucha_.

The specimen described was presented to the Smithsonian Institution by

Dr. Wernigk, and at the time was supposed to be _L. tephrocotis_.

Of this form, nothing as to its habits is known with certainty. It

probably does not differ in any important respect from the allied

races.
