"Myiarchus cinerescens. Ash-throated Crested Flycatcher. Rather olivaceous-brown above, quite brown on the head; throat very pale ash, sometimes almost whitish, changing gradually to very pale yellow or yellowish-white on the rest of the under parts. Primaries edged as in crinitus, but secondares and coverts edged with grayish-white. Tail-feathers as in crinitus, but the rufous of the inner webs hardly or not reaching their ends, being cut off from the tip by widening of the fuscous stripe (in young birds, in which the quills and tail-feathers are more extensively rufous-edged, the last distinction does not hold)Elliot Coues, 1884

"Pitangus derbianus. Derby Flycatcher. Under parts light wood-brown, with an olive tinge; wings and tail the same, but the feathers extensively bordered without and within with chestnut, forming a conspicuous continuous area on the wing-quills in the closed wing, and on most of the wing and tail-feathers more extensively than the brown portion of the inner webs. Below from the breast, including lining of wings, clear and continuous lemon-yellow. Whole chin and throat pure white, widening behind up under ear-coverts. Top and sides of head black, a circle of white from forehead over eyes to nape white, the enclosed black enclosing black a lemon and orange patch. Or, middle of crown yellow and orange, enclosed and partly concealed in black, this black enclosed in white, then the long and broad black bar on side of head, separating the white of side of crown from that of side of throat. The coronal feathers lengthened and erectile as in a king-bird, or more so; crown-patch of same character but more extensive. Bill and feet black; iris hazel Sexes alike." Elliot Coues, 1884

"Myiarchus crinitus. Great Crested Flycatcher. Decidedly olivaceous above, a little browner on head, where the feathers have dark centres; throat and fore pure dark ash; rest of under parts bright yellow, the two colors meeting abruptly; primaries margined on both edges with chestnut; secondaries and coverts edges and tipped with yellowish-white; tail with all the feathers but the central pair chestnut on the whole of the inner web (excepting perhaps a very narrow space next the shaft); outer web of outer feathers with yellowish; middle feathers, outer webs of the rest, and wings except as stated, dusky-brown. 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."

"Terpsiphone paradisi, Paradise Flycatchers, have fine crests, shorter in the female; while fleshy wattles, round or above the eye, of scarlet, blue, or yellow, are found. The bill is sometimes reddish or blue, and the inside of the mouth green or yellowish, as in certain Birds of Paradise. The female is rich bay above, with similar head, but grey cheeks and throat. In other species the males are said to be maroon, cinnamon, chestnut, blue-grey, or glossy-black above." A. H. Evans, 1900

"Sayiornis fusca. Pewit Flycatcher. Water Pewee. Pewit. Phaebe. Dull olivaceous-brown, the head much darker fuscous-brown, almost blackish, usually in marked contrast with the back; below, solid whitish, or palest possible yellow, particularly on the belly; the sides, and the breast nearly or quite across, shaded with grayish -brown; wings and tail dusky, the outer tail-feather, inner secondaries, and usually the wing-coverts, edged with whitish; a whitish ring round the eye; bill and feet black. 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. 53 shows the lobate foot of a coot. In the lobate foot, a paddle results not from connecting webs, but from a series of lobes or flaps along the sides of the individual toes; as in the coots, grebes, phalaropes, and sun-birds. Lobation is usually associated with semipalmation, as is well seen in the grebes (Podicipedidae). In the snipe-like pharalopes (Phalaropodidae), lobation is present as a modification of a foot otherwise quite cursorial. The most emphatic cases of lobation are those in which each joint of the toes has its own flap, with a free convex border; the membranes as whole therefore present a scolloped outline."

"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."
