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 . Head and foot of Avocet, about J 610 SYSTEMATIC SYNOPSIS.—LIMICOL^. and full-webbed ; the bill is decidedly recurved, flattened, and tapers to a needle-like point;the body is depressed; the plumage underneath is thickened as in water-birds. The speciesBwim well. Rimantopus is 3-toed, semipalmate, the bill nearly straight, and not flattened ; inrelative length of leg it is probably not surpassed by any bird whatsoever. These two genera,each of three or four species of various parts of the world, with the Cladorhynchus pectoralisof Australia, compose the RECURVIROSTRA. (Lat. remntts, bent upward; rosirwm, bill. Fig. 425.) Fig. 425 -European Avocet, /iecuri-irostra arocetta, J nat. size (From Brelim.) BiU excessively slender, more or less recurved, then the upper mandible hooked at the extremetip; much longer than head, more or less nearly equalling tail and tarsus ; flattened on top,^without culminal ridge. Wings short (for a wader). Tail very short, square, less than halfthe wing. Legs exceedingly long and slender; tibia? long-denuded; tarsus nearly twice aslong as middle toe and claw: covering of legs skinny. Feet 4-toed; the front toes full-webbed,hind toe short, free. Body remarkably depressed and feathered underneath with thick duck-like plumage ; altogether, as in swiiuming rather than as in wading birds. It is a modification BECUBVIBOSTEID^: AVOCETS AND STILTS. 611 like that seen in the lobe-footed phalaropes. Sexes and young alike; -wdnter and summer plu-mage different (in the North American species at any rate). R. anierica
