"Larus heermanni. White-headed Gull. Bill shorter than head or tarsus, rather slender, moderately compressed, the tip rather acute; its color red in part in the adult. Folded wings reaching beyond the tail. Tail of moderate length, even, slightly emarginate in the young. Feet rather large. Tarsus equal to the middle toe and claw. General colors dark; tail mostly blackish. Adult, breeding plumage: Bill bright vermilion red, black for its terminal third, sometimes wholly red; a red ring around eye. Head white; this color gradually merging on the neck into plumbeous-ash, which extends over the whole under parts, being lighter on the abdomen and under tail-coverts than elsewhere. The back is deep plumbeous-slate, lighter on the rump. Upper tail-coverts clearly ashy. Upper surfaces of wings like the back; the primaries black; the tips of all, except the two or three outer ones, narrowly white. Tail black, narrowly tipped with white. Legs and feet reddish-black."

Wings shorter than usual, 1st primary little longer than next, all rounded. Tail exceedingly long and deeply forked, with very narrow filamentous outer feathers. Tibia slightly denuded; tarsus a little shorter than middle toe and claw. Whole form trim and elegant. Bill black, the extreme point yellowish, the base for a little distance, and inside of mouth, red. Feet bright yellowish-red; claws black. Cap lustrous black, very ample, reaching to lower border of eyes; under eyelid white, as is a streak to end of feathers on bill. Neck all around and entire under parts snowy white, tinted with lovely rose-pink. Mantle delicate pale pearly, over all the upper parts from the neck, including rump and base of tail, fading however to white on tips of tertials and inner webs of secondaries. Long tail-feathers white with a faint pearly tint. Primaries grayish-black, strongly silvered when fresh; outer web of the first blackish; inner webs of all pure white for more than half their breadth, this white stripe broadest on the first, toward the base of which it occupies the whole web, and on all of them continued to and usually around the very tips; shafts of all the quills white both sides nearly to end."

"Sterna (T.) caspia. Caspian Tern. Imperial Tern. Bill dark vermilion red, growing and somewhat "diaphanous" toward the tip. Pileum and occipital crest glossy greenish-black, extending to below the lower level of the eyes, and occupying the termination of the feathers on the side of the mandible to the exclusion of the white; lower eyelid white, forming a noticeable spot on the greenish; a white streak along sides of upper mandible, not extending to the end of the feathers. mantle pearl-blue, the line of demarcation between it and the white rather indefinite, both on nape and rump; most of the tail-feathers, and especially the central ones, retaining a more or less pearly tint. Shafts of the primaries yellowish-white; primaries grayish-black, but, when new, so heavily silvered over as to appear of a light hoary gray, especially on their superior aspects. On the inner web of all there is a central light field; this is very narrow, even on the first primary, although it runs considerable distance, and on the others it rapidly grows less; and it has no trenchant line of division of the primaries from the darker portions of the feather. whole inner web of secondaries pure white, outer pearl-blue. Legs and feet black." Elliot Coues, 1884

"Sterna (T.) maxima. Cayenne Tern. Royal Tern. Adult in summer: Pileum glossy greenish-black, not extending below eyes, so narrow on side of upper mandible that a broad white streak extends to extreme tip of the feathers. Mantle exceedingly light pearl-blue, fading imperceptibly into white on the rump and towards the extremities of the tertials. Tail white, with a faint tinge of pearly, especially on the central feathers and inner webs of the other. Secondaries pure white for their whole length except a small space on the outer web near the tip, which is grayish-blue, deeper than the mantle. Outer web of first primary grayish-black; in the inner web of the same has a space of black extending the whole length of the feather, very narrow at the base, widening as it runs toward the tip. within 1 & 1/2 inches of which it occupies the whole web; the rest of the web white. separated from the black by a straight distinct line of division. The second, third, fourth, and fifth primaries have the same general characteristics, but the white space grows narrow and shorter, and round up further in the centre than along the edge of the web, so that for a little way from its end it has a border of blackish along its outer margin; other primaries wholly pearl-blue, their inner webs margined with white. Bill coral and orange-red, with a slightly lighter tip; feet blackish, their soles dull yellowish." Elliot Coues, 1884

"Sterna (T.) cantiaca. Sandwich Tern. Ducal Tern. Bill black, the tip 1/2 to 3/4 an inch bright yellow, sharply defined against the black; "inside of mouth deep blue." Feet dull black. Pileum and occipital crest glossy black, with a tinge of green; the color extending just below the eyes, but leaving a space along the side of the mandible white to the extremity of the feathers. Mandible exceedingly light pearly-blue, fading on the rump and upper tail-coverts into pure white; but the rectrices themselves have a slight shade of pearly-bluish. Primaries colored as in maxima. On the inner web of the first the black space is broad and deep in color; when about 1& 1/2 inches from the apex of the quill it quite suddenly grows wider, so as to exclude the white portion from the tip altogether. The second, third, and fourth primaries have the same general pattern, but he white runs up further on the central portion than on the edge of the web, so that toward its end it receives a narrow edging of blackish. The other primaries have no blackish, but are simply pearl-blue, with broad white margins along the whole length of heir inner webs. The outer primaries are all heavily silvered when the quills are new.

"Sterna aleutica. Aleutian Tern. Bill of ordinary shape, as in hirundo, macrura, etc., entirely black. Feet small, as in the species just named, but the webs more deeply incised; emargination not so great, however, as in Hydrochelidon; much as in Haliplana. Tibia bare to the usual extent. Wings and tail exactly as in Sterna proper, the latter, in its length and depth of fork, recalling macrura and forsteri. Crown and nape black; a large white frontal crescent, the horns of which reach to the posterior border of the eyes, the convexity of which extends into the nasal fossae, the concavity of which is opposite the anterior border of the eyes; thus broader than in most species similarly marked. The black vertex sends through the eye a band that crosses the cheeks and reaches the bill just posterior to the point of greatest extension of the feathers on the latter. The chin, auriculars, and other parts of the head bordering this vitta below, and pure white, presently deepening insensibly into the hue of the under parts. Tail wholly pure white; no pearly wash on either vane of any of the feathers. Upper parts at large dark pearl-gray, with a dull leaden hue, different from the clear pearly of macrura, etc., yet not of the smoky cast of panayensis, etc.; it is a tint intermediate between these, that I find difficult to name satisfactorily. The whole under parts, from the white of the chin, just noticed, to the under tail-coverts, paler and more decidedly pearly, more nearly as in full-plumaged macrura, yet more grayish. Both under and upper tail-coverts, like the tail, white. The color of the back mounts on the neck behind to the black of the nape without intervention of the white. Under wing-coverts and edge of wing pure white; as are all the shafts of the primaries. Primaries blackish lead-color, with silvery hoariness, and each with a large white space on inner web; this white space on the first primary occupies at the base the whole width of the inner web, but grows narrower toward the tip of the feather, ending about an inch from the tip, which is wholly blackish lead-color, this color running down as a narrow margining of the inner vane for two inches or more."

'Rhynchops. Skimmer. Bill hypognathous Among the singular bills of birds that frequently excite our wonder, that of the skimmers as one of the most anomalous. The under mandible is much longer than the upper, compressed like a knife-blade; its end is obtuse; its sides come abruptly together and are completely soldered; the upper edge is as sharp as the under, and fits a groove in the upper mandible; the jawbone, viewed apart, looks like a short-handled pitchfork. The upper mandible in also compressed, but less so, nor is it so obtuse at the end; its substance is nearly hallow, with light cancellated structure, much as in a toucan; it is freely movable by means of an elastic hinge at the forehead."
