This species is nearly allied to _Anthus aquaticus_ and _A. pratensis_, more especially to the latter, from which it is distinguished by having the bill much stouter, the tarsus longer, the hind claws stouter, more curved, and much shorter, the colour of the feet much darker, in being always much more rufous beneath, and in sometimes, when the summer is advanced, being almost entirely unspotted there. From _A. aquaticus_ it is at once distinguished by the whitish band over the eye, and the white on the outer tail-feathers. It indeed seems wonderful that any ornithologist should have mistaken it for that species. FAMILY XIV. ALAUDINÆ. LARKS. Bill rather short, or of moderate length, somewhat conical, compressed toward the end; upper mandible with its dorsal line sloping and slightly convex, the edges sharp and overlapping, the notches generally obsolete; the tip narrow and a little deflected; lower mandible with the angle of moderate length and narrow, the dorsal line ascending and nearly straight, the edges slightly inflected, the tip acute; gape-line straight. Nostrils elliptical or oblong, basal. Head oblong, of moderate size; neck rather short; body ovate. Feet of moderate length, or rather long; tarsus compressed, with eight anterior scutella; toes slender, compressed; the hind toe elongated, second and fourth about equal, third much longer. Claws rather long, arched, slender, much compressed, laterally grooved, acute, that of the hind toe very long, straightish, tapering. Plumage generally soft and blended. Wings rather long, broad, the inner secondaries tapering, and one so elongated as nearly to equal the longest primary, when the wing is closed. Tail of twelve feathers, generally emarginate. Roof of the upper mandible concave, generally with three prominent lines; tongue slender, thin, flat, tapering to a slit and bristly tip; œsophagus of uniform width; stomach a very strong muscular gizzard of a roundish form and compressed, its lateral muscles very large, its epithelium dense and rugous; intestines short, of moderate width; cœca very small, cylindrical. Nest on the ground. Eggs five or six, oval, spotted. GENUS I. ALAUDA, Linn. LARK.
