. Key to North American birds. Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and Lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds. 262 SYSTEMATIC SYNOPSIS. — PASSEBES— Fig. 122. — Bow-billed Thrasher, thick. (Ad. nat. del. E. C.) nat. size; bill a little too and blackish instead of brown; ends of the rectrices scarcely or not lighter than the rest of these feathers; bill almost entirely dark-colored. Besides these points of coloration, there is a decided difference in the shape of the bill. In H. rufus, the biU is quite straight, and only just about an inch long; the gonys is straight, and makes an angle with the slightly concave lower outline of the mandibular rami. In H. longirostris, the bill is rather over an inch long, and somewhat curved; the outline of the gonys is a little concave, making with the ramus one con- tinuous curve from base to tip of the bill. Size of H. rufus. Texas and Mexico. 19- H. curviros'tris. (Lat. cu/rvus, curved, and rosiris; bow-billed.) Curve-billed Thrasher. ^ 9 : Above, uniform ashy-gray (exactly the color of a mocking-bird), the wings and tail darker and purer brown.

Throat quite white, immaculate, without maxU- lary stripes; lower belly and cris- sum mostly free from spots. No decided markings on the side of the head. Ends of greater and median vring-coverts white, forming two de- cided cross-bars; tail-feathers dis- tinctly tipped with white. BiU black, over an inch Jong, curved, stout; feet dark brovra.
