and tail, uniform dull pale grayish-brown, with narrow^, faintly-rusty edges of the wing- 
coverts and inner quills, and equally obscure whitish tipping of the tail-feathers. No max- 
illary nor auricular streaks; no markings about the head except slight speckling on the 
cheeks. Under parts brownish- white, palest (nearly white) on the belly and throat, more 
decidedly rusty-brownish on the sides, flanks, and criesum, the breast alone marked with 
numerous small arrow-head spots of the color of the back. Bill light-colored at base 
below. $ : Length about 9.25; wing 4.00; tail 4.25; bill 0.87; along gape 1.12; tarsus 
1.25; middle toe and claw 1.12. 9 rather smaller; wing, 3.75, etc. Arizona, less common 
than palmeri, with which it is associated. Nest in bushes; eggs 2-3, about 1.00 X 0.73, 
elliptical rather than oval, whitish, spotted and blotched with reddish-brown. 
H. ciner'eus. (Lat. cinereus, ashy; cinis, cineris, ashes. Fig. 124.) St. Lucas Thrasher. ^ 
9 : Upper parts uniform ashy-brown ; wings and tail similar, but rather purer and darker 
brown, the former crossed with two white 
bars formed by the tips of the coverts, the 
latter tipped with white. Below, dull white, 
often tinged with rusty, especially behind, 
and thickly marked with small, sharp, tri- 
angular spots of dark brown or blackish. 
These spots are all perfectly distinct, cover- 
ing the lower parts excepting the throat, 
lower belly, and crissum; becoming smaller 
anteriorly, they run up each side of the throat 
in a maxillary series bounding the immacu- 
late area. Sides of head finely speckled, 
and auriculars streaked ; bill black, lighten- 
ing at base below, little longer than that of 
H. ritfus, though decidedly curved. Length 
of ^ about 10.00; wing 4.00; tail 4.50; bill 1.12; tarsus 1.25 ; middle toe and claw 1.25. 
9 averaging rather smaller. Young : Upper parts strongly tinged with rusty-brown, this 
color also edging the wings and tipping the tail. The resemblance of this species to the 
mountain mocking-bird {Oroscoptes montanus) is striking. It is distinguished from any others 
of the U. S. by the sharpness of the spotting underneath, which equals that of H. rufus itself, 
the small and strictly triangular character of the spots, together with the grayish-brown of the 
upper parts, and inferior dimensions. Lower California, common. Nest a slight shallow structure 
of twigs in cactus and other bushes; eggs 1.12 X 0.77, greenish-white, profusely speckled. 
H. redivi'vus. (Lat. redivivus, re- 
vived; the long-lost species having 
been rediscovered and so named.

: No spots anywhere ; wings and 
tail without decided barring or tip- 
ping. Bill as long as the head or 
longer, bow-shaped, black. Wings 
very much shorter than the tail.

wings and tail similar, but rather purer brown. Below, a paler shade of the color of the 
upper parts, the belly and crissum strongly rusty-brown, the throat definitely whitish in marked 
contrast, and not bordered by decided maxillary streaks. Cheeks and auriculars blackish- 
brown, with sharp whitish shaft streaks. Length 11.50; wing 4.00 or rather less; tail 5.00 or 
more; bill (chord of culmen) nearly or quite 1.50; tarsus 1.35; middle toe and claw about
