this genus but one species is so far known in the United States, the Rock Wren of the earlier ornithologists. It is peculiar among its cognate genera by having the two continuous plates on each side the tarsus divided into seven or more smaller plates, with a naked interval between them and the anterior scutellæ. Other characters will be found detailed in the Review of American Birds, p. 109.

Salpinctes obsoletus

      Salpinctes obsoletus.

      7157 ♂

      Sp. Char. Plumage very soft and lax. Bill about as long as the head. Upper parts brownish-gray, each feather with a central line and (except on the head) transverse bars of dusky, and a small dull brownish-white spot at the end (seen also on the tips of the secondaries). Rump, sides of the body, and posterior part of belly and under tail-coverts dull cinnamon, darker above. Rest of under parts dirty white; feathers of throat and breast with dusky central streaks. Lower tail-coverts banded broadly with black. Inner tail-feathers like the back, the others with a broad black bar near the end; the tips cinnamon; the outer on each side alternately banded with this color and black. A dull white line above and behind the eye. Iris brown. Length, 5.70; wing, 2.82; tail, 2.40. Young not marked or banded beneath. Eggs white, spotted with red.

      Dr. Coues, in his “Key to North American Birds,” gives an able and extended article on the general characteristics of birds, and on their internal and external anatomy, to which we refer our readers. A paper by Professor E. S. Morse in the “Annals of the New York Lyceum of Natural History” (X, 1869), “On the Carpus and Tarsus of Birds,” is of much scientific value.

      Carus and Gerstaecker (Handbuch der Zoologie, 1868, 191) present the following definition of birds as a class:—

      Aves. Skin covered wholly or in part with feathers. Anterior pair of limbs, converted into wings, generally used in flight; sometimes rudimentary. Occiput with a single condyle. Jaws encased in horny sheaths, which form a bill; lower jaw of several elements and articulated behind with a distinct quadrate bone attached to the skull. Heart with double auricle and double ventricle. Air-spaces connected to a greater or less extent with the lungs; the skeleton more or less pneumatic. Diaphragm incomplete. Pelvis generally open. Reproduction by eggs, fertilized within the body, and hatched externally, either by incubation or by solar heat; the shells calcareous and hard.

      This group is insusceptible of definition. The wading birds, as usually allocated, do not possess in common one single character not also to be found in other groups, nor is the collocation of their characters peculiar.

      Corresponding closely with the Linnæan and earlier Sundevallian acceptation of the term. Equivalent to the later Oscines of Sundevall.

      As remarked by Sundevall, exceptions to the diagnostic pertinence of these two characters of hind claw and wing-coverts taken together are scarcely found. For, in those non-passerine birds, as Raptores and some Herodiones, in which the claw

As remarked by Sundevall, exceptions to the diagnostic pertinence of these two characters of hind claw and wing-coverts taken together are scarcely found. For, in those non-passerine birds, as Raptores and some Herodiones, in which the claw is enlarged, the wing-coverts are otherwise disposed; and similarly when, as in many Pici and elsewhere, the coverts are of a passerine character, the feet are highly diverse.
