2s T o. 12,024, Fort Tejon, Cal.; J. Xantus (type of description of 
var .^mexicamts, adult male , in History North American Birds, iii, 
p. 231):—Forehead, crown, and occiput plumbeous-black, feathers of the 
latter with basal two-thirds snowy-white. Upper plumage deep plum¬ 
beous, darkest anteriorly, the back being scarcely lighter than the 
nape; rump fine bluisli-plumbeous. No concealed white on the upper 
parts. Tail brownish-plumbeous, narrowly tipped with pure white, and 
with four sharply-defined broad bands of black, the first of which is 
faintest, and concealed by the coverts, the last broadest; shafts of 
tail-feathers deep brown throughout. Primaries and secondaries much 
darker than the tail, and more bluish; less so, however, than the 
scapulars. Lores whitish, quite in contrast with the black of the 
forehead ; cheeks and ear-coverts dark ashy, slightly washed with 
reddish, and with obscure darker streaks; chin and throat white, with 
sparse, hair-like shaft-streaks of black. Breast, abdomen, sides, flanks, 
and tibim fine vinaceous-rufous, the feathers (except on tibire) with fine 
hair-like shaft-streaks of black; breast, abdomen, sides, and flanks with 
pairs of transverse elliptical white spots, not touching the shaft; on 
the abdomen, the white and rufous bars are of about equal width; on 
the tibire, the rufous is deepest, and exceeds the white in amount; anal 
region barred with rufous, more faintly than the abdomen; lower tail- 
coverts immaculate snowy-white. Sides of the neck deep reddish-ashy, 
this washing the whole side of the breast. Lining of the wing reddish- 
white, with numerous crowded, cordate, somewhat blended spots of 
rufous; larger coverts transversely spotted with blackish; under side 
of primaries silvery-white (blackish for about the terminal inch), crossed 
with quadrate spots of blackish, of which there are about seven on the 
longest quill (fourth); the basal ones are, however, so much broken 
that the number is rather indefinite. Wing, 9.10; tail, S.20; culmen, 
0.65; tarsus, 2.60; middle toe, 1.50. 
Xo. 66,237, Westfield, Mass., October 10, 1S4G:—Very similar to the 
preceding (Xo. 12,024), but even darker, the rufous of the lower parts 
deeper, and the ashy tinge on the side of the breast still stronger. 
Wing, 9.20; tail, 8.15 ; culmen, 0.G5 ; tarsus, 2.55 ; middle toe, 1.50. 
Xo. G,874, Sacramento Valley, California, differs from the two preced¬ 
ing in having the entire breast barred with rufous and white, instead of 
having the sides ashy, the wfliite bars restricted to the middle portion; 
the black of the pileurn terminates abruptly 011 the occiput, and the 
sides of the neck are tinged with rusty, as in females. Wing, 9.30; 
tail, 8.15; culmen, 0.60; tarsus, 2.45; middle toe, 1.50. It resembles 
Xo. 10,086, except that the colors are uniformly of a darker shade 
throughout. 
Xo. 2,554 (Mus. It. B.), Washington, D. C., differs from Xo. 10,086, in 
paler colors and more delicate shades; the sides of the breast have a 
distinct wash of pearly-ash, while the nape is pale bluish-ash, lighter 
than the back, and abruptly defined against the dark-plumbeous crown. 
Wing, 9.40; tail, 8.30; culmen, 0.65; tarsus, 2.50; middle toe, 1.55.
