288 SYSTEMA TIC SYNOPSIS. — PASSERES — OSCIXES. 



or blackish. These spots are all perfectly distinct, covering 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 ihe immaculate area. Sides of head finely speckled, and 

 auriculars streaked ; bill black, lightening at base below, little longer than that of H. rtifus, 

 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 resem- 

 blance of this species to the Mountain Mockingbird {Oroscoptes montanns) is striking. It is 

 distinguished from any others of the U. S. by the sharpness of the spotting underneath, which 

 equals that of H. riifus itself, the small and strictly triangular character of the spots, together 

 with the grayish-brown of the upper parts, and inferior dimensions. Lower California, from 

 Cape St. Lucas N. to about lat. 30°, common. Nest a slight shallow structure of twigs in 

 cactus and other bushes; eggs 1.12 X 0.77, greenish-white, profusely speckled. 

 H, c. mearns'i. (To Dr. E. A. Mearns, U. S. A.) Mearns' Thrasher. Like H. cinerens; 

 differing in much darker upper parts, becoming bister-brown on the rump and upper tail- 

 coverts, rustier flanks and crissum, larger and blacker spots on under parts, and less curved 

 bill. San Quintin, L. Cala. Anthony, Auk, Jan. 1895, p. 53; A. 0. U. List, 2d ed., 1895,

(Subgenus Harporhynchus.) 



H. redivi'vus. (Lat. redivivns, revived ; the long-lost species having been rediscovered and 

 so named. Fig. 151.) California Thrasher. (^ : No spots anywhere ; wings and tail 

 without decided barring or tipping. Bill as long as head or longer, bow-shaped, black. 



Wings very much shorter than tail. 

 Above, dark oily olive -brown; 

 wings and tail similar, but rather 

 purer brown. Beh)w, a paler 

 shade of color of upper parts ; belly 

 and crissum strongly rusty-brown ; 

 throat definitely whitish in marked 

 contrast, and not bordered by de- 

 cided maxillary streaks. Cheeks 



Fig. 151. — California Thrasher, nat. size. (Ad. nat. del. E. C.) 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 the same. 

 9 similar, rather smaller. Coast region of California from the valleys of the Sacramento and 

 Kussian rivers southward. Abundant in dense chaparral ; nest a rude platform of twigs, roots, 

 grasses, leaves, etc., in bushes; eggs 2-4, 1.15 X 0.85, bluish-green, with olive and russet- 

 brown spots. 



H. r. pasadenen'sis. (Lat., of Pasadena, a place in Cahfornia.) Pasadena Thrasher. A 

 very slightly difl'ereutialed race, continuing the distribution of the species southward to about 

 lat. 30° in Lower California. General coloration " ashier or less distinctly brown " than in 

 redivivus proper ; throat nearly pure white. No appreciable difference in dimensions. In- 

 cluded under redivivus in former eds. of Key. Grinnell, Auk, July, 1898, p. 237 ; A. 0. U. 

 Suppl. List, Auk, Jan. 1899, p. 123. 



H. lecon'tei. (To Dr. John L. Le Conte, the entomologist.) Yuma Thrasher. 

 Le Conte's Thrasher. Size and proportions nearly same as in redivivus; difi'ers very 

 notably in the pallor of all the coloration. Excepting the slight maxillary streaks, there are 

 no decided markings anywhere; and the change from the pale ash of the general under parts
