The sternum rarely conforms to the particular passerine model, its pos- terior border usually being either entire or else doubly-notched. The vocal apparatus is not highly developed, having not more than three pairs of separate intrinsic muscles ; the birds, consequently, are never highly musical. There are some modifications of cranial bones not observed in Passeres. Picaritp, like lower birds, usually lack a certain specialization of flexor muscles of the toes seen in Passeres. This anatomical matter requires special attention, as some important classificatory considerations are involved. The jjasserine rule is, that the flexor liallucis, which bends the hind toe, is perfectly distinct from the flexor perforans, which bends all the other toes ; and that the former has but one tendon, going to hind toe, while the other has three tendons, going to all the rest of the toes. Passerine birds being considered to represent the "normal" (or usual) arrangement, are called nomopelmous ; and all birds which do not have this arrangement I call anomalopelmous. Passerine birds are also called schizopelmous, with reference to the complete separation of the hallucal from the other dig- ital tendons. But the anomalopelmous Picarian birds present several further specializations of the arrangement for bending their toes. In the Hummingbirds the flexor hallucis besides going to the first toe supplies also the second digit by a branch, and sends in addition the rudiments of little slips to the third and fourth digits. In the Hoopoes the arrangement is nearly schizopelmous, but there is a desmopelmous feature beyond the bases of the toes. In the Cuckoos, again, the tendons of the flexor hallucis and flexor perforans are connected by a vinculum or ligament at the point where they cross each other on the way to their respective digits ; they are hence called desmopelmous, and this arrangement is also shared by psittacine and gallinaceous birds. Again, in the Swifts and Goatsuckers, of the group Cypseliformes, the respective tendons of these two muscles are extensively blended to- gether ; they are hence termed sympelmous. Fourthly, in numerous zygodactyle birds, the Woodpeckers and their allies, the flexor perforans has only one tendon, which goes to the " middle" or third toe, i. e. the outer anterior one, while the flexor hallucis splits into two or three tendons, which supply all the other toes ; tliey are hence termed antiopelmoiis. Fifthly, in the Trogons, which are yoke-toed in a diff"erent way from any other birds, by reversion of the second instead of fourth toe, the flexor hallucis has two tendons which supply the two hind toes, and the flexor perforans has likewise two tendons, for the front toes ; they are thus what is called heteropelmous. The technical terms here used of the birds themselves are equally ap- plicable to the anatomical arrangements ; one may speak, for example, of anomalopelmous feet, or anomalopelmous tendons, as well as of anomalopelmous birds. Three of the five arrangements noted for Picarian birds, the sympelmous, antiopelmous, and heteropelmous, are peculiar to this group. With regard to the ambiens muscle, it is absent in most Picarice, which are there- fore anomalogonatous ; but present in the homalogonatous Cuckoos and their near relatives the Turacous. Externally, the feet are very variously modified; one or another of all the toes, ex- cept the middle one, is susceptible of being turned, in this or that case, in an opposite from the customary direction ; the fourth one being frequently capable of turning either way; while in five genera of Picidce and one genus oi Picumnidce the first, and in two genera oi Alcedinidce the second, toe is deficient. When all four toes are turned forward, as in the Colies, the feet and their owners are termed pamprodacti/lous. When there are three in front and one behind, as in Kingfishers, the term anisodactylous is used ; and when the digits of such a foot are extensively soldered together, the formation is called syndactylous. In some cases, as the family Microj)odid(B or Swifts, some members of it are pamprodactylous, others anisodactylous. A very frequent arrangement is that of toes in pairs, two behind and two before ; most such yoke-toed birds have the properly zygodactylous arrangement, by reversion of the fourth or outer toe, as in the Woodpeckers, Cuckoos, and others; but in the Trogons alone the second or inner toe is the reversed one, and the arrangement is styled heterodactylous. The tarsal envelop is never entire behind, as in the higher Passeres. Another curious peculiarity of the PIC A RLE: PICA RI AN BIRDS. 539 feet is, that the claw of the hind toe is smaller, or at most not larger, than that of the third toe ; and on the whole the hind toe itself is inconsiderable, weak if not wanting, not always perfectly incumbent and apposable. The wings, endlessly varied in shape, agree in possessing ten developed primaries, of which the first is rarely spurious or very short. (Notable excep- tions to this occur in the Pici with spurious first primary, and in the Indicatoridce, with only nine primaries.) A very general and useful wing-character is, that the coverts are larger and in more numerous series than in Passeres ; the greater coverts being at least half as long as the secondary quills they cover, and sometimes reaching nearly to the ends of these quills. This is the common case among lower birds, but it distinguishes most of the Picaria; from Passeres; it is not shown, however, in the Picidce and some others, as the Indicator idoe, Meya- Ifemidce, and Rhamphastidce. The wing is quintocubital as a rule (with variability in Alcedi- nidte and some Cypselidce'). The tail is indefinitely varied in shape, but the number of its feathers is a good clue to Picarue. There are not ordinarily more than ten perfect rectrices, and occasionally there are only eight, as in the Anis (Crotophaga') ; the AVoodpeckers have twelve, but one pair is abortive ; there are twelve, however, in the Kingfishers, Puff'-birds, Indicators, and some others ; ten or twelve indifierently in the Motmots. Pulviplumes occur in the Leptosomatidce an«l Podargidce. The bill shows numberless modifications in form, and lias its own specialization in nearly every family ; it assumes some of the most extraordinary sliapes, as in the Hornbills and Toucans, and is seldom of the simjde style seen in a Thrush or Finch; it is never hooked and cered, as in Parrots and Birds of Prey, nor soft and swollen at the nostrils, as in Pigeons. With this sketch of some leading features of the group (it will oes; the Toucans, witli their enormous bills, behmg to the series vvhidi includes the Barbels, I'uti'-birds. Jacaiiiars, and Woodpeckers; and otlier sucii instances could be cited. 540 SYSTEMATIC SYNOPSIS. — PIC ARI^. There are more than 1,800 species of Picarice, and the order as a whole is cosmopolitan. But it is richest in geneni and species in the tropical regions of either hemisphere, and most of the families occur only in limited areas, especially the Ethiopian and neotropical. Thus, the Leptosomatidae are peculiar to Madagascar, and the Todidce to the Antilles. Exclusively Ethiopian are the Irrisoridce, Coliidce, and Musophagidce ; Ethit)pian and Oriental are the Indicator idee, Upupidre, Bucerotidce, Meropidce, Coiaciidce, and three of these families (not Indicatoridte or Bucerotidce) are represented in Europe. Exclusively neotropical are the Rhamphastidce, GalbuUdce, Bucconidce, Momotidie, and Steatornithidee ; while the Trochilidee are characteristic of the same region, but have a few nearctic representatives. The PodargidfB are Oriental and Australian. Two families, Trogonidce and Capitonida, are remarkable in being represented alike in the tropical portions of both hemispheres. The Alcedinidce are widely dispersed in the Old World, with one American genus. Finally, the Micropodidce, Capriimdgidce, Picidce, and CucuUdce are well represented in both temperate and tropical regions of both hemispheres. The very numerous genera fall in at fewest the foregoing 24 families, which are universally recognized. The o}>en questions are, whether a family Maeropterygidce should not be dis- sociated from the Micropodidce, a family Nyctibiida from the Cajn'imulgida, a family Centro- podidm from the CucuUdce., and the families Picumnidce and lyngidce from the Picidce. Without prejudice to these points, the 24 conceded families may be disposed in nine superfam- ilies or suborders, according to the following arrangement, which is much more natural than that given in former editions of the Key. The seven North American families, representing as many major groups, are marked with the asterisk, and will be fouud more fully characterized beyond, under their respective heads.

Musophagid^ It must be obvious, from the foregoing exhibit, that no linear arrangement of the groups can possibly exhibit tlieir various interrelations; and consequently, any sequence of the families we may adopt becomes a choice of evils. By common consent, the highly specialized Tro- chilidce stand at or near the '* head " of the series, and near or next to them come the Micro- podidce (Cypselidce). Again, the homalogonatous Cuciilidce and Musophagidce, differing most from all the rest, and even hinting at gallinaceous affinities, are best put at the " foot " of the series. But between these extremes there is room for wide difference of opinion in arranging the families of the whole order, even when we have only those of North America to deal with. It will be observed that our seven families represent as many of the whole number of suborders, only the Pamprodactyli (the Colies) and the Upupce being unrepresented in our fauna. Now the XTpupce are certainly "high" in the Picarian series, with their passerine feet, etc. — so high that Salvin makes them head the order, even taking precedence of the TrocMlidce. Yet their closest relationships are with the BuceroUdce, or Hornbills ; and to bring out this fact I am obliged, in the foregoing schedule, to bring in the Halcyones next after the UpnpcE. But this arrangement has the disadvantage of throwing the Caprimidgidce far out of their unde- niable bearing upon the Cypselidce, and so upon the Trochilidce ; for the actual relationships of these three families are so close that with most authors they form one suborder — the so-called Macrochires, Cypseliformes, or CypselomorplicB. In a faunal work like the present it may not be necessary to insist upon considerations involved in the relationships of the H(jopoes and Hornbills; and it is easy to bring the Caprimnlgid/e next after the Cypselida;, by simply trans- posing the places occupied by the Halcyones and Coracicv in the foregoing scheme. Making this single change, the sequence of our seven suborders and seven families becomes : Trochili, Trochilidce; Cypseli, Micropodidce ; Coraci^, Caprimnlgidce ; Halcyones, Alcedinidce : Trogones, Trogonidce ; Pici, Picida; ; and Coccyges, Cuculidce. This arrangement seems to me to be as " natural" as any tliat can be devised; it certainly brings out some good points. TROCHILIDyE : HUMMINGBIRDS. 543 as in placing the yoke-toed (vvliether heterodactylous or zygodactylous) families together, after the anisodactylous or pamprodactylous ones ; it heads the list with the Humuiers, and foots it with the Cuckoos ; and it violates no obvious interrelations of the intermediate famihes. Hav- ing these recommendations, this is the sequence I shall adopt in the present edition of the Key.* Suborder TROCHILI : Hummingbirds. See p. 540 for analytical characters of this group, especially in comparison with the tissi- rostral macrochirous type — the Ci/jiseli. The skeleton agrees closely, iu general, with that of the Swifts, but has many minor peculiarities in detail, among which the most prominent are the modifications of the facial bones conformably with the long slender bill. The palatal ar- rangement is schizognathous. The deeply carinate sternum widens toward its uunotched xiphoid border; there is no manubrium; the furculum is U-shaped, with rudimentary hypo- clidium ; the coracoid canaliculate; the humerus very short and stout, the radius arched, the metacarpus and phalanges greatly elongated. A chief anatomical peculiarity is the structure of the tongue, which somewhat resembles a Woodpeckei-'s in being protrusible or capable of being thrust far out of the beak by a muscular mechanism connected with the long horns of the hyoid or tongue-bone, which curve up around the back of the skull ; the tongue is in efl'cct a sheathed double-barrelled tube, appearing like two cylinders united for some distance, tlien opening out with a thin lacerated edge. This structure is supposed to be used to suck the sweets of flowers. There are no cseca, and the oil-gland is nude. The myological formula lacivs the ambiens, accessory femorocaudal, semitendinosus, and its accessory, as in the Swifts ; the flexor longus hallucis supplies the hallux and by a branch the second digit, besides sending the remnants of slii)s to the third and fourth ; the second, third, and fourth digits are supplied as usual by the flexor digitorum. There are no sterno-tracheals. There is one carotid artery, the left. The pterylosis is characteristic. This is a highly monomorphic or monotypic group, containing a single definitely circumscribed family, peculiar to America, and specially charac- teristic of the Neotropical region. Family TROCHILID^ : Hummingbirds. Tenunostral macrochirous Picaricc. These beautiful little creatures will be known on sight by their diminutive size and gorgeous coloration, without regard to their technical char- acters. They are called Hummingbirds because their wings make such a noise in flight, whirring so rapidly that the eye cannot follow their vibrations. The French know them as oiseaux-mouches, or "bird-flies," for the same reason; their curious resemblance to insects has struck every one who ever saw a Hummer pcnsed on misty pinions before a flower, when a second glance might be refpiired to distinguish the feathered bird from a furred sphinx-moth. In ])owers of flight the Hummers are equalled by few if any birds, and certainly surpassed by none iu the marvellous rapidity with which they dart through the sunsiiiue. ^ • The arranRement in former editions of the Key is: Ctpseliformes, Caprimiilffidir, Ci/psrlidir, Trochilidcr ; CucuLiFORMEs, Troffoniilip, Alreiliiiklir, Cuciilktif ; Picifokmes, I'irkia-. This is bad, both in the construction of sub- orders and sequence of families. In the classification atlopted in tlie A. O. U. Lists there is some faulty construction of three major groups as in Key, with an improvement in their sequence. Reversing the A. O. U. arrangement, which pro- ceeds from lowest to highest, in order to correctly exhibit its relations with the foregoing, we find it to be : Order Macro- CHtREs ; Suborder Trix hili, Troc/iilitftr ; Suborder Cypseli, Afitropoilidir ; Suborder Caprimuloi, Caprimiilgitlir. Order Pici ; no suborder, /'Iriilir. Order Coccyges ; Suborder Alcyones. Alcediniritiiul(jiit(r from Ciijisilidir and Trm/iilidir His seipience rever.sed, or from highest to lowest, is, for the foregoing families : Tro- chilidir, Miiiiiiiodidrr, Tniiioiiidir, J'icidtr, Alcriliiiidir, Cfipriiniilijiiltr, Cuciilidtr. Both the numl>er and the sequence of groups, so far as those of North America are concerned, as given in the foregoiug text, are identical with those presented iu the British Museum Catalogues. 544 SYSTEMA TIC SYNOPSIS. — PICARl.I^ — TROCHILI.

The cutting edges of the mandibles are inflected, and either serrate, serrulate, or smooth ; the rictus is devoid of bristles. The nostrils are linear, with a supercumbent scale or operculum, sometimes naked, oftener feathered. In size the Hummers average the least of all birds, the giants among them alone reaching a length of 6 or 7 inches, the pygmies being under 3 inches ; the usual stature is 3 or 4 inches. In a few the coloration is plain, or even sombre; most have glittering iridescent tints — "the most gorgeously bril- liant metallic hues known among created things." The sexes are usually unlike in color. Hummingbirds, like poets, belong to the genus irritahile ; they are very nervy if not also brainy little creatures, of greater courage than discretion, quick-tempered and extremely pug- nacious— the Kingbird which has just whipped a Hawk or a Crow maybe assaulted and worsted by the impetuous Ruby-throat. The food of Hummers was formerly supposed to be the sweets of flowers. It is now known that they are chiefly insectivorous. Their little nests are models of architectural beauty. The eggs are always two in number, elliptical in shape, and white in color. The young hatch weak and helpless, requiring to be fed by the parents, Hummers being thus of altricial nature. The voice is not musical. The family is one of the most perfectly circumscribed in ornithology, and one of the largest groups of its grade. So intimately and variously are the genera interrelated that every attempt to divide it into subfamilies has proven unsatisfactory. Hummers are peculiar to America. Species occur from Alaska to Patagonia ; but we have a mere sprinkling in this country. The centre of abundance is in tropical South America, particularly Colombia. Nearly 500 speciniens are current. The genera or subgenera vary with authors from 50 to 150. Mr. D. G. Elliot, one of the highest authorities upon the subject, gives 426 species, assigned to 125 genei'a. The latest monographer, Mr. Osbert Salvin, one of the most careful and critical ornithologists who ever lived, arranges the Hummers in 3 series called Serrirostres, Inter- medii, and Laevirostres, with 127 genera and 480 species. None of the known North Ameri- can Hummers exhibits the extremes of shape of bill or tail which some of the tropical genera TR OCHILIDJE : HUMMINGBIRDS. 545 illustrate; in only one (Calothorax lucifer) is the bill decidedly curved. Only one species is more than 5 inches long — the magnificent Coeligena clemendee. Some curious shapes of tail, including marked sexual characters in this respect, are exhibited by certain genera, especially the wonderful Loddigesia. Only one species, the common Ruby-throat, is known to occur in the East ; this was the only one known to Wilson. Audubon gave four species, but one of them erroneously. Since his time, many new forms of these exquisite creatures have successively been brought to light over our Mexican bor- der. In 1858, Baird gave seven (one of them Lampornis mango, erro- neously, as Audubon liad done). In 1872, in tlie Key, I was able to in- crease the number to ten, but with two wrongly given (the Lamponiix and Agyrtria linncii). The same ten, with the two errors, were given by Baird and Kidgway in 1874. Within ten years the discoveries were so many, that, after eliminating the two er- rors, I was able to de- scribe in 1884 no fewer than fifteen perfectly distinct species of United States Hummingbirds ; and I then stated that I had no doubt that several others would in due time be found over our Mexican border. The sixteenth (Coeligena clemendee) was added to the 3d ed. of tlie Key, 1887; the seventeenth and eighteenth (Tro- chiliis violijugidaris and S. floresH) were installed in the 4th ed., 1890. I have now to include the nineteenth (Basilinna Irucofis). But Afthi>< heUmfP is not confirmed, reducine: fur the present the total to eighteen. Among the probabilities are Lamprolccma rhami and Cam- pglopterus hemileucurus. The discrimination of the females and young is difficult ; but witli the adult males there should be no trouble. The following table is intended to enable the student to tell the genus and species directly of any United States Hummer, if tlie specimen lie has in iiand be an adult male. If a female or young, he must refer to the detailed descriptions. He will be much as- sisted by the figures of generic details drawn from nature by Mr. R. Ridgway for Mr. D. G. Elliot's monograpli, and kindly loaned to mv by Professor Baird. Fig. 355. — Ruby-throated Hummingbirds, (f, 9i and nest, nearly nat. size. (Sheppard del. Nichols sc.)

Nidification various, always peculiar. Eggs several (except in the Tree Swifts), narrowly oval, white. Young hatched naked and helpless. " One of the most remarkable points in the structure of the Cypselidce is the great devel- opment of the salivary glands. In all the species of which the nidification is known, the secretion thus produced is used more or less in the construction of the nest. In most cases it forms a glue by which the other materials are joined together, and the whole nest is affixed to a rock, wall, or other object against which it is placed. In some species of Collocalia, how- ever, the whole nest is made up of inspissated saliva, and becomes the ' edible bird's nest ' so well known in the East." (Sclater.) The student will have observed that the characters of the MicropodidcB as above drawn require several exceptions to be taken in the case of the genus Macropteryx (or Dendrochelidon) , which contains five or six species of East Indian Tree Swifts, difieriug notably from other Swifts. The osteological peculiarities of these birds are decided in several respects, aftecting the bones of the skull, sternum, fore-arm, tarsus, and toes (see Lucas, Auk, Jan. 1889, pp. 8-13). The plumage is peculiar, approaching that of Caprimulgine birds; the egg is stated to be single, and the nidification to resemble that of the Frog-mouths (Batrachostomus). The departure of the Tree Swifts from Micropodidce proper is on the whole in the direction of the^ Caprimulgi. If we exclude this remarkable genus as the type of a separate family Macropterygidce or Dendrochelidonidce, the remaining Swifts form a well defined family of 8 genera and about 75 species, inhabiting all the temperate and tropical regions of the globe. They are divisible into two subfamilies, mainly according to the structure of the feet ; and both of these divisions are represented in North America. Analysis of Subfamilies and Genera. MiCROPODlN^.

Ratio of phalanges abnormal, the 3d an^ 4th toes having each 3 joints like the 2d ; basal phalanges of all the anterior toes very short (fig. 40). Hind toe reversed (in Micropiis or Cypselus), or lateral (in Aeronautes and Pamjptila). Tarsi feathered (in Micropus) ; toes also feathered (in Aeronautes and Panyptila). This subfamily contains about one-third of the species of Swifts, most of which belong to the genus Micropus. This genus is chiefly Old World, but two South American species are referred to it by late authority. Panyptila is a neotropical genus, to which our Rock Swift has usually been referred ; but in Panyptila the tail is deeply forked, with acuminate lateral feathers (compare Aeronautes^ below). There are two species of Panyptila, P. cayanensis and P. sancti-hieronymi. An interesting feature is shown by the group of Palm Swifts, in which, as first pointed out by Hartert, there is a MICROPODIDyE — MICROPODINuE: TYPICAL SWIFTS. bbl curious sort of spurious zygodactylism ; for the toes are in right and left pairs, the third and fourth toes being one side, the first and second on the other side. In the typical Palm Swifts, constituting the genus Tachornis as now restricted and defined, the toes are naked. There are several Old World species, and one West Indian (T. phcenicohia) . The other genus of Palm Swifts has feathered toes ; its single species, Claudia squamata, inhabits South America. The Palm Swifts " build tiny nests agglutinated with saliva to tlic leaves of palms," while the species oi Micropus usually nidificate in holes in rocks, about buildings, etc, only occasionally in trees. The most remarkable nests in. the whole subfamily are those constructed by the Swifts of the geuus Panyptila, which glue together plunt-seeds to form a tube about two feet lung, hung to the under side of an overhanging rock or tree trunk, with the entrance at the lower end of the tube, and a shelf at its top inside, like a cornice or bracket, on which the eggs rest.

Forehead and line over eye ])ale; a velvety black space before eye. Bill black ; feet drying yellowish. The purity of color varies with wear of the feathers, some specimens being dull sooty brownish, others more purely and even glossy blackish. The extent of white along belly is very vari- able. The flank-patches are conspicuous, in life sometimes almost meeting over rump. Length 6.50-7.00; extent about 14.00; wing about the same as length ; tail about 2.()r), forked, soft. Western U.

S. range, but resident on and near our southern border; occurs in Lower California and on some of the islands; not yet known to occur in Gregon, Washington, or anywhere N. of the U. S. ; breeds in suitable places throughout its U. S. range. Thi.s is a large and beautiful Swift — a high-fiior of almost incredible velocity, witli a loud shrill twitter, nesting in tlie most inaccessible cliffs, sometimes by thousands, in May, June, and July. The nest is securely placed far in holes and crevices of rocks or indu- -rated earths, usually at a great height; it is a saucer-like structure, about 5X2 inches, with a shallow cavity, made of various vegetable materials well glued together with saliva, and lined with feathers. Eggs several, in one instance 5, narrowly subelliptical, 0.87 X 0.52, vhite. Tiie name of this bird seems as hard to fiiwl as its nest and oggs !

An- terior toes cleft to base (no webbing). Hind toe not reversed, but sometimes versatile ; our species have it obviously elevated. Tarsi never feathered; naked and skinny, even on the tibio- tarsal joint. In the prin- cipal genus, Chcetura, containing about two-thirds the species of the subfamily, of various parts of the world, the tail-feathers are stiflened and mucronate by the pro- jecting rhachis. There are over 30 species of these spine-tailed Swifts, in several sections of the genus, by some systematists ranked as separate genera (especially Hemiprocne) ; but they are much alike, and our familiar Chimney Swift is a fair example of them all.

(Genus Nephoccetes Baird, 1858, correctly JSfephcecetes, as in former editions of the Key, p. 457, where it is said to be "scarcely different'' from Cypseloides ; and I am glad to see that it has been replaced by Cypseloides in the A. 0. U. Lists.) C. ni'ger borea'lis. (Lat. nicjer, black ; borealis, northern. Our species is a variety of the West Indian C wi^rer. Fig. 374.) Northern Black Cloud Swift. Adult i^ 9 : Entire plumage sooty-black, with slight greenish gloss, little paler below than above; feathers of head and belly with grayish edges. A velvety black area in front of eye ; forehead hoary ; eyelids partly naked. Bill black ; feet probably dusky-purplish in life. Length 7.00 or more ; wing the same; tail 2.75, forked nearly 0.50 in adult ^, merely emarginate in 9 j tarsus 0.50; middle toe and claw about the same. Young: Tail rounded; plumage dull black- ish, nearly every feather skirted with white, especially noticeable on belly, rump, and upper tail-coverts and inner wing quills; crissum mostly white; supposed to require several years to perfect the black plumage. Rocky Mts. to the Pacific, U. S. and British Columbia; a great black Swift still imperfectly known; supposed to nest in cliffs up to 11,000 feet: ranges to about 13,000; crops found filled with Ephemeridce. The bird breeds in holes and crevices in cliffs, often inaccessible, like the Rock Swift, in June and July, and it has been observed in so many localities during the breeding season that it may be confidently stated to nest in suitable places nearly or quite throughout its North American range. It is migratory with us, arriving over our borders late in April, and returning in September. It is more common in the Pacific coast region than in the interior, and ranges S. in winter to Costa Rica. The West Indian habitat once assigned was an error, it being that of AT. niger proper, from which our bird differs decidedly in being larger — average wing measure- ments over G.50, instead of about G.OO. I am at a loss to understand why the A. 0. U. micropodid.e—ch.eturinjE: spine-tail swifts. 559 persisted in refusing to recognize borealis as a subspecies till 1897, when it accepted the position I had maintained in the Key since 1872 : see Auk, Jan. 1897, p. 12t), No. 422. The bird is recognized as a full species by Dr. Sclater, and as a good subspecies by Mr. Hartert; and Major Bendire also separates the two forms, though he does not venture to differ from the A. O. U. in nomenclature (Life Histories, ii, 1896, p. 175). The differ- ences are at least as great in size as those separating Chcetura vauxi from C pelagica. In these days, when North American Ornithology has been thoroughly Brehuiized, with hair- splitting and heart-rending super-refinements, the present case can only be explained as a miracle.

Unicolor or bicolor (our species one-colored, sombre.) Se.xes alike. C. pela'gica. (Gr.

The IlfXacryoi or Pelasgi were anciently a nomadic tribe, and the implication of the term in ornithology is supposed to be the bird's migration, without any ref- erence to the sea.

In districts still primitive, however, it continues to use hollow trees, to which it resorts by thousands to roost. Not impossibly winters in such retreats in a lethargic state ! The dry twigs for its pretty basket -like nest are snapped ofl' the trees by the birds in full flight. No soft lining is used ; the nest is shaped like half a saucer, 3 or 4 inches across by 2 or 3 in the other width, and less than an inch deep ; the twigs used are from half an inch to 2 inches or even more in length, and a sixteenth to Fig. 377. — Nest and Eggs of Chunuey Swift. an eighth of an inch thick, usually much varnished over with the dried saliva. The eggs are 4-5, seldom 6, 0.70 to 0.80 long by 0.53 broad, thus narrowly elliptical, and pure white. So great are the volitorial powers of this bird, that the sexes can come together on the wing.

Nest and eggs as in the common species; eggs averaging a trifle smaller. This species still uses hollow trees to breed in, but is already beginning to utilize chimneys. Note. — One or two other species of this genus, representing the subgenus Hemiprocne, may be expected over our border — especially the Collared Swift, Hemiprocne zonaris- of Mexico, etc. This is a large handsome bird, blackish, with a white collar around the neck behind, and a white breast ; length about 9.00; wing nearly as much; tail 3.00. The Half- collared Swift, H. semicollaris, also inhabits Mexico. Suborder CORACI-^ : Coracian Birds. See p. 541 for characters of this group, framed to include the five families Leptosomatidcey Coraciida;, Capritmilgidce, Podargidce, and Steatornithid(e. Only one of these, the Capri- midgidce, is North American. In former editions of the Key, this family included the Podar- gidce and Steatornithidce, and was brought under a suborder Cypseliformes, corresponding exactly to the "order" Macrochires, of the present A. 0. U. classification, and including the Trochilidce and Micropodidce. (It should be observed here that the original Macrochires of Nitzsch included only the " long-handed " families, the Swifts and Hummers, as did also the precisely equivalent Cypseliformes of Garrod ; but that the Cypseliformes of Coues, like the Cypselomorplice of Huxley, combined the Caprimidgidce with the Cypselidce and Trochilida;.) But the undeniably close relations of the Goatsuckers, Swifts, and Hummers are overbalanced by the closer affinities of the Caprimulgiue Birds with the Rollers and Kirumbos ; hence the present association of all the Coracian birds in one suborder. The Steatornithida;, a mono- typical neotropical family consisting of a single species, Steatornis caripensis, the Guacharo CAPRIMULGID.E: GOATSUCKERS. 561 or Oil-bird, is so peculiar in many respects that it is sometimes set apart in a superfamily or suborder Steatornithes (see p. 541 for characters); otherwise the transition from the Caprimul- gidce on the one hand, through the Podargidce, to the Leptosomatidce, and thus to the Cora- ciidce, on the other hand. A curious evidence of affinity between these families may be witnessed in the lofty tumbling of our Night-hawks, comparable with those aerial evolutions which have given the Kollers their name. A marked feature of Coracian birds is the presence of pulviplumes in some of the families. The conformation of the palate is too various to fur- nish decisive indications; it is of a type called iegithognathous or schizognathous in one of the families, but desmognathous in the others. The syrinx is tracheo-bronchial, or pseudo-bron- chial, or bronchial; in the latter case there are of course a pair of syringes, as in Steatornis ; the syringeal muscles are not more than one pair. The oil-gland is nude, if present ; there are cfeca. The sternum is deep-keeled, 2- or 4-notched. The spinal pteryla forks over the shoulders. Two carotids occur (always '^). The ambiens is absent ; neither is there any ac- cessory femorocaudal, and in Steatornis the femorocaudal itself is missing ; the flexor digitorum profundus, and not the flexor hallucis, supplies the hallux, by the sympelmous arrangement of tendons. The feet are anisodactylous, in the Kirumbos imperfectly zygodactylous by versatil- ity of the 4th digit ; in the true Goatsuckers this digit lacks one phalanx ; there are also some other peculiarities of the feet, which as a rule are very small, weak, and scarcely fitted for pro- gression, or even for perching in an ordinary fashion. The rectrices are 10 or V2 ; primaries 1(1; secondaries more than 7. The suborder as a whole consists of nocturnal Picarian birds, with more or less resemblance to Owls; the Oil-bird is quite owlish, and even so diurnal a fam- ily as the Rollers contains nocturnal species. The suborder as a whole is nearly cosmopolitan ; but four of its five families inhabit restricted areas, and only one is common to both hemispheres. Tliis is the Family CAPRIMULGID^ : Goatsuckers.

Suborder HALCYONES: Halcyoniform Birds. See p. 540 for analytical characters of this suborder, as framed to include the five families BucerotidcB, Alcedinidte, Momotida, Todidce, and MeropidcB. The first and last of these are exclusively Old World ; the second is chiefly Old World, with one American genus ; the third A L CEDINTD. E : KINGFISHER S. 571 is Neotropical, the fourth Antilloun. The suborder is less compact than most others oi Pica- rice, and includes birds of such extremely dissimilar external appearance as the tiny Todies, no larger than some Hummingbirds, of dainty aspect and brilliant plumage, and the great gaunt ungainly Hornbills, witli their monstrous beaks and sombre or sordid hues. The feet are ani- sodactylous, with three toes in front and one behind (anomalous exception in t\vo3-toed genera of Kingfishers, lacking the 2d digit), and more or less perfectly syndactylous, having the anterior toes united for some distance in a single flat fleshy sole. They are also sympel- mous by blending of the flexor tendons of the toes, whereof the hallu.x is sup- plied by a slip from the flexor digitorum perforans, not from the flexor hallucis. The spinal pteryla is well defined and not branched over the slioulders, and the ventral tract has an open space. The palate is desmognathous in the five families, and in none of them are there basi})terygoids ; the sternum is usually 4-notched or 4-fenestrate except Buce- rotidfe. The oil-gland aud c*ca are f.g. 3S7.- Head of bi,k -...:. ...-bin, nat. size. variable in the several families. The myological formula is A X Y (except in Alcedinidcp, where it is A X, as in Troyonidcc), the fenK>rocaudal, semitendinosus and its accessory present, but accessory femorocaudal absent, like tlie ambiens. The plumage is aftershafted in Momo- tidce and Meropidce. The rectrices are oftenest 12, often 10. The most peculiar family is the Bucerotidce, which some authors set apart in a group by itself; its relationships appear to be with the Uimpce. [Family MOMOTID^: Sawbills. Feet syndactylous by cohesion of third and fourth toes (p. I'-i'i); tomia serrate. Plumage aftershafted. No ceeca. Two carotids. Sternum 4-fenestrate.

In this species, the central tail-feathers are long-exserted, and spatu- late by absence of webs along a part of the shaft — a mutilation which is naturally progressive in this family, and may be facilitated or expedited by the birds tliemselves ; bill is about as long as iiead, gently curved ; nostrils rounded, basal, exposed ; wings short and rounded; tarsi scu- tellate anteriorly- Color greenisli, with top nf head blue, encircled with black ; long auriculars black, and a bnuch of Idack, or l)iue aud black, feathers on breast; middle tail-featliers blue toward ends, witli l)la(k tips.

Feet very small and weak, scarcely or not ambulatorial ; tibiae naked below; tarsi extremely short, reticulate in front; hallux short, flattened underneath, its sole more or less continuous with sole of inner toe; soles of outer and middle toe in common for at least half their length; inner toe always short, rudimentary, or wanting (in two genera, Ceyx and Alcyone — -an abnormal modification). Developed toes always with normal ratio of phalanges (2, 3, 4, 5; p. 133); middle claw not serrate. Wings long, of 10 primaries. Tail of 12 rectrices (only 10 in the racket-tailed Tanysijitera) variable in shape. Two subfamilies ; all Old World excepting one genus. "The Kingfishers form a very natural family of the great Picarian order, and are alike remarkable for their brilliant coloration and for the variety of curious and aberrant forms wliich are included within their number. . . . ' Their characteristic habit is to sit motionless watching for their prey, to dart after it and seize it on the wing, and to return to tlieir original position to swallow it.' . . . The Alcedlnidce nest in holes and lay white eggs. It is, however, to be remarked that, in accordance with a modification of the habits of the various genera, a corre- sponding modification has taken place in the mode of nidification, the piscivorous section of the family nesting for the most part in holes in tlie banks of streams, while the insectivorous section of the family generally nest in the holes of trees, not necessarily in the vicinity of water." (Sharpe.) One would gain an imperfect or erroneous idea of the family to judge of it by the American fragment, of one genus and 6 or 8 species. According to the author of the splendid monograph above cited, there are in all 125 species, belonging to 19 genera. They are very unequally dis- tributed. Ceryle alone is nearly cosmopolitan, absent only from the Australian region ; the northern portion of the Old World has only 2 peculiar species ; 3 genera and 24 species are char- acteristic of the Ethiopian region : one genus and 25 species are confined to the Indian ; while no less than 10 genera and 59 species are peculiar to the Australian. The species are now known to be over 150 in number, but this increase does not materially affect the items just given regarding their distribution. In the subfamily DacelonincE, which contains a majority of the genera and species, the bill is more or less depressed, with smooth, rounded, or sulcate cul- men; and these birds are hardly " fishers,'' kingly or otherwise, for they live in the woods and are mainly insectivorous. The largest genus is Halcyon, with over oO species. The next largest is Tanysiptera, containing the 20 racket-tailed species ; Ceyx has nearly as many 3-toed species ; one of the most notable birds of the subfamily is the Laugliing Jackass of Australia, Dacelo gigas. In the Subfamily ALCEDININ/E, Piscivorous Kingfishers, the bill is compressed, with carinate culmen. Ceryle is the only American genus, with 3 North American species, others in South America, and several more in Europe, Asia, and Africa. The other Old World genera are Pelargopsis, Alcedo, CorytJiornis, and Ceyx, the latter 3-toed. The Alcedinince are all thoroughly aquatic and piscivorous, seeking their prey by plunging into the water from on wing ; and nest in holes in banks, laying numerous white eggs. CE'KYLE. (Gr.
