"Another small family, characterized by the extreme length of the slender legs, and the extreme slenderness of the long acute bill, which is either straight or curved upward. Recurvirostra is a 4-toed, 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 species swim well. Himantopus is 3 toes, semipalmate, the bill nearly straight, and not flattened; in relative length of leg it is probably not surpassed by any bird whatsoever.

In architecture the frieze is the wide central section part of an entablature and may be plain or—in the Ionic or Corinthian order—decorated with bas-reliefs. Even when neither columns nor pilasters are expressed, on an astylar wall it lies upon the architrave ('main beam') and is capped by the moldings of the cornice.In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long stretch of painted, sculpted or even calligraphic decoration in such a position, normally above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made of may be plasterwork, carved wood or other decorative medium.This image is "intended to convey an idea of the details of decoration which characterized the Renaissance style during its best period, and which display considerable grace and finish. They are based on the antique Roman type, but still display a peculiar independent treatment, as in the deeply under-cut foliage in the arabesques and the lightness and clearness of the stalks and tendrils."

The Stilt Sandpiper, Micropalama himantopus or Calidris himantopus, is a small shorebird. The Stilt Sandpiper breeds in the open arctic tundra of North America It is a very long-distance migrant, wintering mainly in South America. It occurs as a rare vagrant to western Europe. This species nests on the ground, laying three or four eggs. The male has a display flight. Outside the breeding season, this bird is normally found on inland waters, rather than open coasts.

Body depressed; the under plumage thick and duck-like, to resist water. feet highly natatorial' toes, including the hinder, lobate, being furnished with large semicircular membranous flaps. The Coots are eminently aquatic birds, swimming with ease, by means of their lobate feet, like phalaropes and grebes; but this ability results from very slight modification of a structure shared by the Rails and Gallinules. There are about ten species, of both hemispheres, distinguished, among other characters, by the size and shape of the frontal shield. That, for instance, is of an exotic species, much larger than that of Fulica americana, and differently shaped. One species is remarkable for having the forehead singularly carunculate; the others closely resemble our common species." Elliott Coues, 1884

"Dromaeognathous skull of ostrich, nat. size specimen no. 16,629, U.S. Nat Museum, by Dr. R. W. Shufeldt, U.S.A. RR, rostrum, beyond which the ossified nasal septum continues in the axis of the skull to the letters "Pmx." V, the short vomer, borne upon R, uniting laterally with Mxp, the broad maxillo-palatines; Pl, palatines, remote from rostrum, underrunning beyond Mxp, but not to Pmx. Pt, expanded scroll-like pterygoids, atriculating behind with Btp, the strong basipterygoid processes on the body (not rostum) of the sphenoid; they underlap R, but do not articulate there. Pmx, premaxillaries; Mx, maxillaries, whose ends run forward to opposite the letters "Pmx"; jugal; qj, quadrato-jugal; Qu, quadrate. (N.B. This is the most exceptional case of dromaeognathism. Each of the Ratite families - Struthionidae, Rheidae, Casuariidae, Dinornithidae, and Apterygidae, - as well as the Carinate family Tinamidae, offers a special case of such formation, as explained in the text.)."

"Dromaeognathous skull of a tinamou (Tinamus robustus); copies by Shufeldt from Huxley. Letters as before; Mxp, maxillo-palatine. The tinamous, Dromaeognathae "have a completely struthious palate"; vomer very broad, uniting in front with broad maxillo-palatine plates as in Dromaeus; behind articulating with posterior ends of palatines and anterior ends of pterygoids, both of which are thus prevented, as in all Ratitae, from any extensive connection with the rostrum; basipterygoid processes springing from body of sphenoid, not from its rostrum, articulating with pterygoids very near the posterior or outer ends of the latter; head of quadrate with a single articular facet, as in Ratitae."

"Schizognathous skull of common fowl, nat. size, from nature, by Dr. R.W. Shufeldt, U.S.A. Letters as before; Pa, palatine. Schizognathism is a kind of " cleft palate" shown by the columbine and gallinaceous birds, by the wader at large, and many of the swimmers. In this general case, the vomer, whether large or small, tapers to a point in front, while behind it embraces the basisphenoidal rostrum, between the palatines; these bones and the pterygoids are directly articulated with one another and with the basisphenoidal rostrum, not being borne upon the divergent posterior ends of the vomer; the maxillo-palatines, usually elongated and lamelar, pass inwards over (under, when the skull is viewed upside-down, as it usually is) the anterior part of the palatines, with which they unite and then bend backwards, along the inner edge of the palatines, leaving a broader or narrower fissure between themselves and the vomer, on each side, and do not unite with one another or with the vomer."

"Desmognathous skull of mallard duck, Anas boscas, nat. size, from nature, by Dr. R.W. Shufeldt, U.S.A. Letters before. In the "bound-palate" type, the vomer in either abortive, or so small that it disappears; when existing it is usually slender and tapers to a point in front; the maxillo-palatines are united across the median line, either directly or by means of ossification in the nasal septum; the posterior ends of the palatines and the anterior ends of the pterygoids articulate directly with the rostrum (as in schizognathism). This type is simply and perfectly exhibited by a duck in which the maxillo-palatine is a broad flat plate united with its fellow in mid-line; the oval sessile basipterygoid facets are far forward, opposite the very ends of the pterygoids."

"Fratercula corniculata Horned Masking Puffin. Crown of head grayish-black, narrowing to a point at base of culmen. Sindes of head white; the postocular furrow and sides of lower jaw ashy. A distinct narrow line of white along edge of fore-arm. Entire upper parts glossy blue-black; a sootier shade of black encircling the fore-neck, running forward on throat to bill. Other under parts white, except a few elongated blackish feathers on sides of flanks. Lining of wings pearly-ash. Bill entirely vermilion-red, even the basal collar; edges of eyelids red; excrescences of eyelids bluish-gray; iris brown; feet orange-red, the webs tinged with vermilion; claws brownish-black; rosette of mouth bright yellow-orange. Lunda cirrata. Tufted Puffin. Crests about 4 inches long, straw-yellow, some of the posterior feathers black at base; these bundles of silky, glossy feathers with very delicate shafts and loosened webs; they chiefly sprout from what corresponds to the furrow in the plumage of F. artica. Face white, broadly of this color on sides of head to beyond eyes (as far as the crests), narrowly across forehead and chin, the bill being thus entirely surrounded by white. Crown between the crests, and entire upper parts, excepting the extreme forehead and a line along the forearm, glossy blue-black. Entire under parts, excepting extreme chin, and including sides of hind head and sides of neck, sooty brownish-black, more grayish on the belly, the lining of wings smoky-gray, the under tail-coverts quite black. Wings and tail black, their inner webs brownish-black, the shaft of the primary whitish underneath near base. Bill, feet, and eye-ring vermilion-red; the basil parts of the bill when about to desquamate showing more yellowish or enamel color, or even showing the living color of the subjacent membrane. Rosette of mouth yellow. Claws black." Elliot Coues, 1884

"Simorhynchus cristatellus. Crested Auk. Snub-nosed Auk. Bill fundamentally small and simple, compressed-conic, with convex culmen and little sinuate horizontal commissure; but in the breeding season developing several corneous appendages, which alter its shape greatly, make it singularly irregular, and modify even the outline of the feathers at its base. These accessory pieces are: a nasal plate, filling the nasal fossa, separate from its fellow of the opposite side; a subnasal strip prolonged on the cutting edge of the upper mandibles backwards from the nostrils; a rosette-like plate at base of upper mandible just over angle of the mouth; a large shoe encasing the posterior part of the under mandible; the latter single, the other three pieces in pairs, making seven in all which are moulted; all these elements vermilion or coral-red; end of the bill enamel-yellow. (Before acquiring these growths the young bird is tetraculus of authors; the adult in winter, after shedding the, is dubius.)" Elliot Coues, 1884
