"Somateria fischeri. Spectacled Eider. Bill (in both sexes) peculiar in the extension upon it of dense velvety feathers which reach to a point on the culmen beyond the nostrils, thence sweeping past the nostrils obliquely downward and backward to the commissure, the nostrils opening just beneath the line of feathers. Feathers of chin extending in a point nearly as far as those on culmen.

"Falco mexicanus. American Lanner Falcon. Prairie Flacon.

Under parts white, everywhere excepting on the throat marked with firm spots of dark brown, most linear on the breast, then more broadly oval on the belly, enlarging and tending to merge into bars on the flanks, very sparse or obsolete on the crissum, on the maxiliary region forming a broad firm moustache; these marking corresponding with the ground color of the upper parts. Primaries ashy-brown, with narrow but firm pale edging of outer webs and ends, the inner webs regularly marked with white in form of barred indents or circumscribed spots, most numerous and regular on the outer primaries; the white tinged with fulvous, next to the shafts; the outer web of the first primary either plain, or with whitish indents as in F. lanarius; outer webs of secondaries more or less marked with fulvous; axillars plain dark brown; lining of wings otherwise white, spotted with dark brown. Tail pale brownish-gray, nearly uniform, but with white tip, and more or less distinct barring or indenting with whitish, especially on the lateral feathers, producing a pattern not unlike that of the primaries.

The foregoing phrases are intended to be chiefly antithetical to those used in describing cinerescens, below, No. 375. Other diagnostic points are: bill dark but not quite black, pale at base below; stout and comparatively short, hardly or not as long as tarsus, the latter perhaps never .90, the olive back, ash throat, and yellow belly severally pure in color; all tail-feathers but middle pair so extensively rufous on inner webs that a mere line, if any, of fuscous persists next the shaft (compare erythrocercus and cooperi), and this fuscous line,if any, running of same narrowness to ends of the feathers (compare cinerescens); never more than a trace of rufous on outer webs."

Varies greatly in shade; the foregoing is the average spring condition. As summer passes, the plumage becomes much-duller and and darker brown, from wearing of the feather; then, after the moult, fall specimens are much brighter than in spring, the under parts being decidedly yellow, at least on the belly."

"Fig. 62 Skull of common fowl, enlarged. from nature by Dr. R.W. Shufeldt, U.S.A. The names of bones and some other parts are printed, requiring no explanation; but observe the following points: The distinction of none of the bones composing the brain-case (the upper back expanded part) can be found in a mature skull. The brain is contained between the occipital, sphenoidals, squamosals, parietals and part of frontal; the ethmoidals belong to the same group of cranial bones proper. All other bones, excepting the three otic ear-bones, are bones of the face and jaws. The lower jaw, of five bones, is drawn detached; it articulates by the black surface marked articular with the prominence just above- the quadratic bone. Observe that from this quadrate a series of bones quadrato-jugal, jugal, maxillary-makes a slender rod running to the premaxillary; this is the zygoma, or jugal bar. Observe from the quadrate also another series, composed of pterygoid and palatine bones, to the premaxillary; this is the pterygo-palatine bar; it slides along a median fixed axis of the skull, the rostrum, which bears the loose vomer at its end. The under mandible, quadrate, pterygoid, and vomer are the only movable bones of this skull. But when the quadrate rocks back and forth, as it does by its upper joint, its lower end pulls and pushes upon the upper mandible, by means of the jugal and pterygo-palatine bars, setting the whole scaffolding of the upper jaw in motion. This motion hinges upon the elasticity of the bones of the forehead, at the thin place just where the reference-lines from the words "lacrymal" and "mesethmoid" cross each other. The dark oval space behind the quadrate is the external orifice of the ear; the parts in it to which the three reference-lines go are diagrammatic, not actual representations; thus, the quadrate articulates with a large pro-otic as well as with the squamosal. The great excavation at the middle of the figure, containing the cirlet of the unshaded bones, is the left orbital cavity, orbit, or socket of the eye. The mesethmoid includes most of the background of this cavity, shaded diagonally. The upper one of the two processes of bone extending into it from behind is post-frontal or sphenotic process; the under one (just over the quadrate) is the squamosal process. A bone not shown, the presphenoid, lies just in front of the oval black space over the end of basisphenoid. This black oval is the optic foramen, through which the nerve of sight passes from the brain-cavity to the eye. The black dot a little behind the optic foramen is the orifice of exit of a part of the trifacial nerve. The black mark under the letters "on" of the word "frontal" is the olfactory foramen, where the nerve of smell emerges from the brain-box to go to the nose. The nasal cavity is the black space behind nasal and covered by that bone, and in the oval blank before it. The parts of the beak covered by horn are only premaxillary, nasal, and dentary. The condyle articulates with the first cervical vertebra; just above it, not shown, is the foramen magnum, or great hole through which the spinal medulla, or main nervous cord, passes from the spinal column. The basioccipital is hidden, excepting its condyle; so is much of the basisphenoid. The prolongation forward of the basisphenoid, marked "rostrum," and bearing the vomer at its end, is the parasphenoid, as far as its thickened under border is concerned. Between the fore end of the pterygoid and the basisphenoidal rostrum, is the site of the basipterygoid process, by which the bones concerned articulate by smooth facets; further forward, the palatines ride freely upon the parasphenoidal rostrum. In any passerine bird , the vomer would be thick in front, and forked behind, riding like the palatine upon the rostrum. The palatine seems to run into the maxillary in this view; but it continues on to premaxillary. The maxillo-palatine is an important bone which cannot be seen in the figure because it extends horizontally into the paper from the maxillary about where the reference life "maxillary" goes to that bone. The general line from the condyle to the end of the vomer is the cranial axis, basis cranii, or base of the cranium. This skull is widest across the post-frontal; next most so across the bulge of the jugal bar." Elliot Coues, 1884

"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."
