. 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 . aU, each, about 4.00;bin 0.fi6; tarsus 1.00 or more. Young: Vermiculated below with dusky, upon a brownishground, about to the same extent as is seen in very old examples of L. borealis. G-eneral tone ofthe upper parts less pure than in the adult; scapulars and tail-ooverts not purely white; blackbar of head less fii-m, but as far as it goes maintaining the characters of the species. At avery early age, the upper parts, including the whitish of the scapulars and tail-coverts, are finelyvermiculated with dusky waves. The ends of the quills, wing-coverts, and tail-fea, thers oftenhave rusty or rufous markings. Extreme examples of exeubitorides look very different fromJ/udovieioMus proper, but the two are observed to melt into each other when many specimensare compared, so that no specific character can be assigned.
