and tail, uniform dull pale grayish-brown, with narrow, faintly-rusty edges of the Aving- 

 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 crissum, 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 lather smaller; wing, 3.75, etc. Arizcma, less common 

 than palmeri, with which it is associated. Nest in bushes; eggs 2-3, about 1.00X0.73, 

 elliptical rather than oval, whitish, spotted and blotched with reddish-brown. 



22. H. ciner'eus. (Lat. einerews, ashy; cims, cmem, ashes. Fig. 124.) St. Lucas Thrasher. ^ 

 9 : Upper jiarts uniform ashy-brown ; wings and tail similar, but I'ather 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 tMcldy 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. rufiis, though decidedly curved. Length 

 of <J 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. rufiis 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. 



23. H. redivi'vus. (Lat. redivivus, re- 

 vived ; the long-lost species having 

 been rediscovered and so named.

 (J : No spots anywhere ; wings and 

 tail without decided barring or tip- 

 ping. Bill as long as the head or 

 htnger, bow-shaped, black. Wings 

 very much shorter than the tail. 

 Above, dark oily olive-brown, the Fig. 125. — California Thrasher, nat. size. (Ad. nat. del. E. C.) 

 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- 

 browu, wdth 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
