. 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. Illustrated by 6 steel plates and upwards of 250 woodcuts. Birds. 92 SYLTICOLID^, WARBLERS. GEN. 30, 31. As at present constituted, the Sylvicolidce, comprising upwards of a hundred genuine species, may be considered to represent, in America to -which they are confined, the Sylviidce or typical Old World warblers. I divide them into three subfamilies, uniting the Geothhjx>incB of Baird with the true Sylvicolince. Their characters, mostly borrowed from Baird's excellent analysis, will be found in full beyond ; here they may be shortly contrasted : — Sylvicolince. — Wings longer than tail (except in Geothlypis) ; commissure slightly curved, with short bristles or none. —-Wings shorter than tail; commissure much curved, unbristled. SetopJiagince. — Wings longer than tail; commissure slightly curved, with bristles reaching beyond the nostrils. Subfamily SYLVICOLIN^. Warblers. Bill conoid-elongate, shorter than the head, about as high as, or rather higher than, wide opposite the nostrils, not hooked, but with a slight notch, or none, at tip ; commissure straight or slightly curved ; a few rictal bristles, reaching little if any beyond the nostrils, or none. Wings pointed, longer than the narrow, nearly even tail (except in Geothlypis). This group is specially characteristic of North America; all the genera and the great majority of the species occirrring within our limits in summer, though most of them winter in the West Indies, Mexico and Central America. Dendrmca, the largest and most beautiful genus, is particularly characteristic of the Eastern United States. All are strictly insectivorous, though not such expert flycatchers as the SetopJiagince; none rank high as songsters, though they have pleasing notes in springtime. With us, they are all migratory. *** Ge
