Eyton, Esq. delivered an interesting geological lecture to the members of this institute and their friends, at their room over the Market Hall. After noticing the opposition the early geologists had experienced from the apparent irreconcilability of the principles of the science with holy writ the lecturer proceeded toexplain the forma- tion of soils by the disintegration of rocks, drift, &e. He then gave a lucid description of the creation of the vari- ous strata by acqueous deposits, and their subsequent disruption by voleanie agency, and the removal of boulders by ice to great distances from the place of their original deposit. He then took a rapid Survey of the _geological formations from Caernarvonshire to London, method of taking observations of the dip, &c. ‘The lecture was illustrated by a number of beautiful diagrams, shewing the extraordinary forms into which the various strata are sometimes forced by the upheaving of the igneous rocks beneath, and the cause of the great Light- moor fault in the coal-field of this county. We were surprised that the importance of the science (especially in this neighbourhood), and the high position of the lecturer, did not attract a larger number of members || than were assembled on Friday.

In preparing the following work, the chief aim of the Author has been not the invention of new species, but the establishment of old ones, in which he flatters himself he has succeeded. Very few synonyms of the older authors on Ornithology not having been reconciled, the chief part of those that remain (with the exception of Forskall, of whose descriptions we cannot make any thing) may be placed to the score of varieties. The list of synonyms, he is perfectly aware, might have been increased to a much greater extent, but this would have much extended the work, and not, he conceives, have answered any good purpose. Many new species are also for the first time described: for the unlimited use of the specimens lately brought home by him from South Africa, and now exhibiting at Egyptian Hall, the author takes this opportunity of thanking Dr. Andrew Smith, who will shortly publish plates of the new species of that valuable collection in this and the other classes. His warmest thanks also are due to the gentlemen in charge of the National Collection, and to the Council and Curators of the Zoological Society, for the facilities afforded him in examining their respective collections. To the Earl of Derby, Charles Darwin, Esq. William Yarrell, Esq. and also to the author of that beautiful work the « Birds of Europe,” he is much indebted for access to their notes and specimens. In the course of the work anatomical cha- racters have for the first time been used for families, sub-families, and genera, where the author considered he had sufficient grounds to establish them; but as the number of specimens of foreign anatidz he has been enabled to obtain in a fit state for dissection has necessarily been very limited, he earnestly requests the assistance of those gentlemen who have it in their power towards this important branch, in forwarding to him foreign specimens for dissection, recent or preserved in spirits or brine, which he shall always think well worth carriage from any distance. Since the greater part of this work was printed we have received Mr. Swainson’s volume of Dr. Lardner’s Cyclopedia, entitled « Animals in Menageries.” ‘There is little new in it as regards the class we at present are endeavouring to illustrate, the greater part of the letter-press being copied from Latham. ‘The following changes in nomenclature, however, occur, as regards which we shall leave our readers to judge for themselves, merely stating that we cannot agree with Mr. Swainson in them: viz. the specific name of the only known species of Cereopsis is changed from Nove Hollandie to Australis ; the semipalmated goose (Anas semipalmata, Lath. Choris- topus semipalmata nobis) is placed in Dendrocygna, Sw. being the same genus in which Anas PREFACE. arcuata, Horsf. has heen before placed by Me. Swainson, and on which species he instituted the genus; the musk duck (Carina moschata, Flem.) is placed in the same genus with the common sheldrake (Tadorna) ; the blue-winged teal (Anas discors, Linn. Cyanopterus discors nobis), the Baikal teal (Anas formosa, Linn. Querquedula formosa nobis), and the Java teal ( Anas Java- nensis, Lath. Querquedula Javanensis nobis), are all placed in Genus Boschas, Sw. together with the common wild duck. The specific name also of Javanensis is altered to Javanica. We have also, since the printing of our generic characters, seen an article in the “ Penny Cyclopedia” (Fuliguline) relating to a portion of the Anatide, in which we are informed that the generic appellation of Chauliodus has been pre-occupied : as we find on reference this to have been the case, we venture to propose that of Ktinorhynchus instead, alluding to the comb-like appearance of the lamelle on each side of the bill. In the Catalogue of European and American Birds, just published by the Prince of Musignano, the generic name Chauliodes is altered to Chaulelasmus, Gray, which had priority to our name for the same genus, having been published first; and Fuligula Americana, Bonap. is altered to Aythya Erythrocephala, Bonap. which genus we do not think a good one; its true name, there- fore, will be Fulegula Evythrocephala. Brehm’s work “ Hanbuck der Naturgeschite aller vogel Deutschlands” would have been scarcely worthy of notice, had it not been that some new genera had been instituted in it, and also the synonyms of Boie, which are valuable, as they forestall many of those given by authors in this country. Looking at the work, however, altogether, it is worse than those of the older authors as regards the creation of false species, five or six species in many instances being made of one.

Berore entering upon a description of the group we propose to illustrate, it may not be amiss to make a few observations on some of the divisions at present in use among Ornithologists, ‘more particularly Genera and Species, for we regard all other divisions, if indeed Genera are not so, as certainly to a great extent arbitrary, and constituted merely for the convenience of the student in Zoology, that he may at once turn to the required species or group he may wish to find, instead of, as would be the case if he consulted the works of Buffon, having to turn over volumes before he would be able to find the wished-for place. When we use the term arbitrary, as applied to divisions of the animal kingdom, let them be called either classes, families, sub-families, or by any other name, we mean, that in forming them there are generally rejected as many points of connection between contiguous groups, and often stronger ones, than those made use of for their division. Divisions and arrangements of some sort are, however, absolutely necessary for the Zoologist, under each of which should be stated the points of connection it bears to others. Much has been said and written on analogy and affinity, and the connection by one or the other of them between the groups and species of the animal kingdom. We have not, however, been able to distinguish between them in any other manner than that the former is generally applied when the groups or species between which a connexion is supposed to exist are far removed from each other, and the latter when nearly related, we shall use the terms indiscriminately, as convenient. A definition of species again presents to the Zoologist in particular another difficulty. The generally received opinion is that of John Hunter, viz. that hybrids between true species will not be productive; and this, we are inclined to believe, is partially correct, but not entirely so, as some birds, ina state of domestication, have bred together, and their offspring been productive, although differing most materially in external form. It may be advanced, however, and with truth, that those animals upon which this experiment has been tried have invariably been brought from countries far apart, and that consequently in a wild state the experiment has never been tried; no fact, that we are aware of, can be brought forward towards an answer to this objection. Should it prove true, that animals inhabiting different countries, and with slightly different forms and colouring, are of the same species, and we confess there is good reason for supposing that this may be the case, it can only be accounted for in this mode, namely, that at the universal distribution of animals after the Deluge, those of the same species, and derived from the same parents, going to different localities, have in a succession of ages been influenced by various local circumstances, as climate, the plentitude, the want, or nature of food, which causes have changed their form, colouring, and, in many instances, their habits. We have nothing whatever to urge against this theory, and we find much in favour of it, considering the different varieties of the human form and habits, although we cannot for a moment suppose that they are derived from other than the same common parents, and that the distinctions between the different races are caused otherwise than solely by climate, yet do we make B % INTRODUCTORY CHAPTER. species of animals inhabiting the same countries, where man has undergone changes equal to any specific character we are able to give between his inferiors. As far, however, as our data at present go, the theory of Hunter, excepting those animals in a state of domestication, appears to be the true one, and we shall here take the liberty of referring our readers to some short papers by us in the Zoological proceedings for 1837, and to Loudon’s Magazine of Natural History, No. VII. New Series, and also to a Note appended to a paper by Mr. Blyth, in volume IX. page 511, of the same Magazine. That man is subjected to a change in complexion as well as in the formation of the skull, when acted upon by different climates, appears from the following quotation:—* In Cairo, and throughout the northern provinces, those (Mooslim Egyptians) who have not been much exposed to the sun havea yellowish but very clear complexion and soft skin, the rest are of a considerably darker and coarser complexion. The people of Middle Egypt are of a more tawny colour, and those of the more southern provinces are of a deep bronze or brown complexion, darkest towards Nubia, where the climate is hottest.” Vide «An Account of the Manners and Customs of the Modern Egyptians, by W. Lane, Vol. I. Library of Entertaining Knowledge.” From a paper read at the meeting of the British Association, held at Liverpool, by Dr. Warren (of Boston, U. S.), it appears that the crania of Indians found buried in mounds in North America, and on that account called the Mound Indians, differ in form from those of the Indians at present inhabiting the same country, and agree with those of the Peruvians now inhabiting South America. Are the present North American Indians the posterity of these Mound Indians? What evidence is there that they are not? The geographical distribution of animals is a subject of much interest to the Zoologist as well as to the Geologist, and very closely connected with the distinction of species, more nearly so, indeed, than is generally supposed. Mr. Swainson divides the earth into five Zoological provinces, corresponding with the continents of Europe, Asia, Africa, America, and Australia; these are well known divisions of the world, and as such are convenient, but we must consider that those countries occupied by the different races of mankind (except where emigration of late date has taken place) form much more natural Zoological provinces than those mentioned by Mr. Swainson. The division of the human species which appears to be most generally approved and adopted is that of Blumenbach: with the characters of these races we have at present nothing to do, but shall refer those of our readers who wish to investigate the matter further to the “Decades of Crania,” by the author above quoted, to the «Regne animal,” and Dr. Prichard’s “ Researches into the Physical History of Man.” We shall, however, make use of that division of the Mongolian variety slightly hinted at by Cuvier, separating from it the Samoides or Lapland race, and it is a singular fact that the Zoology of the country, as well as the human inhabitants of it, form the connecting links between the Zoology and human inhabitants of the three great continents, Europe, Asia, and America. The following divisions or ranges are those which we think the most natural :— The Caucassian range occupies the whole of Europe, excepting only Lapland and Finland, that part of Asia to the west of the Caspian sea, and the rivers Obe and Ganges. The Mongolian range occupies that part of Asia not inhabited by the Caucassian races, except Malacca. INTRODUCTORY CHAPTER. 3 The Esquimaux range contains those most northern parts of the three continents of Kurope, Asia, and America, not occupied by the other races. The Ethiopian or Negro range is confined to Africa, together with the island of Madagascar. The American range occupies the whole of that vast continent, except the parts north of a line drawn from the northern side of Hudson’s Bay to Cook’s Inlet, which forms a part of the Esquimaux range. The Malay range contains Malacca, Australia, and the intermediate islands of the Pacific and Indian Oceans, extending as far northwards as the Phillipine Group, New Zealand, and New Guinea. The numerous islands not mentioned are considered as belonging to the ranges to which they are contiguous, The advantage of this arrangement of the globe is simply that the zoology of the country occupied by each range will, in a great measure, as far as we have been able to ascertain, be found to be peculiar, thé central portions of each district beg occupied by a race of animals as well as by a variety of man distinct from those of the other ranges, the borders of each district, or those points at which they approach one another, being as it were inhabited by a mixed zoology, many of the species and Genera of either of the contiguous ranges being found in it. There are, however, certain birds of great power of flight found distributed to a very large extent over the surface of the globe, the Kestril and Peregrine Falcon may be enumerated as examples. The object we have in view in this detail is an attempt, however imperfect, to shew that the same districts occupied by the various races of man are also occupied by various races of animals, each differing from the races of man and. animals in the other ranges, and that it is exceedingly probable that as the races of man are merely varieties, one of the other those of animals may also be so. And why is it, we may ask, in any way improbable that, at the dispersion of man and animals after the flood, the same causes may not have influenced both? We can observe even in the present state of science and observation some instances in which a parallel between animals and the human race, inhabiting the same countries, can be traced, and it may be expected that as science advances these parallels will increase: any one acquainted with this subject, upon seeing a box of African bird skins, will at once, without examining each species, say from whence they came, by their general appearance, and the darkness of their hues; the negro race from the same countries is also dark. Mr. Swainson, in volume 66 of Lardner’s Cyclopedia, observes, that European Ornithology is characterised by the great number of Genera it contains in proportion to the number of species. There are also, perhaps, more sub-varieties of the Caucassian race than of any other, caused, probably, by the great variety of the climates. The birds and animals of the Esquimaux range are nearly all migratory ; the human inhabitants of the country are also seldom stationary for long together in the same spot, for the same reason, the want of food. Thus, in some instances at least, we see that man and animals are influenced by the same cause, and why, therefore, is it by any means improbable that many of the animals, inhabiting different countries, and allowed to be allied, are of the same species, but have, by local causes, through a succession of ages, become altered ? Although we have said much, perhaps too much. on this subject, and, we fear, tired our A INTRODUCTORY CHAPTER. readers, let it be understood that the whole is merely brought forward as a conjecture, to which, whatever data we have been able to collect being given, we leave our readers to decide with regard to the probability or the contrary of it. Should it, however, prove true that many now supposed species, inhabiting different countries, are the same, and merely varieties, it will not lessen im any degree, or make less interesting or important, the labours of the zoologist; for, in an intellectual point of view, can any thing be more interesting than to unravel what appears to be a mystery, and, in an useful one, to point out such animals as will breed together, and thereby open the way to improvement in our varieties of domesticated animals. In the internal arrangements of the group we intend to illustrate we shall deviate from the course followed by other authors, and propose one which, as far as we have been able to carry our investigations, appears to be in harmony with both the external and internal organization of each genus. We must here mention it as a subject of regret, that, although our utmost endeavours have been used, we have been totally, on account of their rarity in this country, unable to obtain either subjects for dissection, or even a sight of the skeletons, of many Genera. Many parts throughout the group appear to be in favour of Mons. Temminck’s opinion, that there are no such divisions as Genera in nature, the transition from one extreme of form to another being so gradual that it is difficult to say where to draw the line of division. Upon a minute examination, however, as far at least as we are at present acquainted with the species, there is always found some break as it were between the forms constituting contiguous Genera or Subgenera, and some tangible distinction between them, although in many particulars they appear closely to approach. It is probable, however, that many new forms will yet be dis- covered; therefore, in the present state of science, it is impossible to say whether this opinion of Mons. Temminck’s will eventually prove true or not. Should it be correct, a serious difficulty will arise with regard to nomenclature, in designating the objects to be named by a specific appellation alone. If we do not admit Genera we cannot admit families, orders, or classes ; the transition will, therefore, we contend, be complete through all, before we can abolish the one or the other. We shall now add a few words on the characters we have employed. Measurements are always subject to a certain degree of variation ; we have, therefore, when the opportunity has offered, given a mean of two or three. ‘The number of tail feathers is far too variable a character to be admitted into any ornithological work. We have now before us three specimens of Erismatura rubida, in which, although in this genus the tail is an important member, the numbering of each differs. We have, for the first time, as far as we are aware of, made use of anatomical characters for divisions, taken from the trachea and skeleton principally ; this has not been done without due consideration, and the examination of a great number of specimens. We have no doubt that some will find fault with us on account of the shortness of the descriptions at the head of each specific character, the use of these, at least what we have supposed it to be, is, that in looking over a large number of descriptions we may readily catch some mark whereby the object we wish to name may be distinguished, perhaps, in common with one or two others from its congeners, and thus that the time taken to read over a large number of long descriptions will be saved. The characters of the Genera, and the cuts of bills and feet, are invariably taken from the species we have named as the generic type, unless it is mentioned to the contrary.

The intestinal anatomy of the family Anatid@ is characterised by the very great length of the alimentary canal compared to that of the bird: in some instances it is as many as five times its length, or even more. The cecal appendages are also much elongated, being often equal to more than one-third the length of the body. The stomach is always large and muscular, forming a true gizzard. ‘The cesophagus varies little in its diameter, but is generally slightly enlarged a little above the gizzard, again contracted, and then of nearly uniform diameter to the glottis. The skeleton may be known by the length of the neck, and the great number of vertebrae of which it is composed, the large size of the sternum, the great developement of its keel and the form of its posterior extremity, which is always perforated by two foramina or indented by two fissures ; the great length as well as breadth of the pelvis; the laterally flattened and anteriorly arched form of the rami of the os furcatum. The truncate form and great depth of the occipital portion of the cranium in a vertical direction, and by the fibula not being entirely anchylosed to the tibia. Affinities. Considerable resemblance to the Divers is shewn in the Mergine and Erisma- turing in outward form, in the structure of the tail and the dense oily nature of the plumage. The ANATIDE. | 6 latter make an evident approach to the cormorants in particular ; nothing, however, is known of their anatomy. The Merging in their anatomy shew an affinity to the euillemots and the genera allied to them, chiefly consisting in the great developement of the keel of the sternum, and in its posterior edge being armed with an ensiform process. The pelvis also is much narrower and more elongated than is the case among the rest of the dnatide. The elongated head to the tibia pos- sessed by all true divers is also slightly apparent in the genus Mergus. We are aware by some authors that the Flamingo has been admitted among the anatide, chiefly on account of its slightly laminated bill and palmated feet, and some portions of its intestinal anatomy resembling this family: we cannot, however, follow this arrangement for the following reasons. Characters for the larger divisions of birds are taken from the external organs necessary to procure their food, especially those of progression. The divisions of each of these have been made, on the other hand, chiefly from the different modifications of the bill.* Let us, for imstance, take the order grallatores: we have there divisions or families formed for feeding on fish, mollusca, earth worms, and small insects: there is one general character of the skeleton through all. Not so with the bill and organs of digestion, which are modified, the former to procure and the latter to assimilate the different kinds of food necessary for the subsistence of the bird. The same rule we shall find hold throughout all the different orders of birds, namely, that the skeleton and structure of the legs and feet will invariably furnish a sure guide to the Order ; while, on the other hand, the bill and organs of digestion supply characters for further subdivision. What we have said above is by no means meant to imply that no modifications of the skele- ton exist in the different divisions of each order, for such is not by any means the case; some slight one always being to be found where there is a change of habit,—in other words, in the modes in which the various kinds of food are obtained. The application of what we have said to the case in question is self-evident, that the fla- mingoes, having the organs of progression and skeleton peculiar to grallatorial birds, consequently must be placed in the order Grallatores, and that the bill and organs of digestion are fitted, the one for procuring, and the other for assimilating its natural food,—minute animalculee obtained at the edges of waters by wading and not by swimming. The webbed feet also possessed by this bird peculiarly fit it for walking on the soft mud and sand, commonly found on shores; their structure, however, is not that of any modification among the anatide, but essentially that of a crane, which bird has them also shightly webbed. * Where such is not the case the orders and families are evidently unnatural.

We prefer taking the genus Anas, as at present restricted, for the type of this sub-family, instead of Rhynchaspis, as proposed by Mr. Swainson, regarding that form and the nearly allied one of Malacorhynchus, rather as ultra than typical, and not so well suited to what may be termed the true habit of the sub-family as that we have chosen. 25 [ANATINE.

Depth of cranium to its length as 1 to 21. Affinity. The disposition to rigidity, and the form of the tail, as well as that of the bill and feet, evidently point out an affinity to the next family ; while the skeleton approaches to that of the genus Mergus, both in possessing an ensiform appendage to the sternum, and in the form of the inferior larynx.

The shortness of the wing deprives these birds of any great power of flight, consequently the species have not a wide geographical range. We are not aware that the use of the stiff tail feathers found on birds of this family and the cormorants has ever been ascertained, and which character appears to separate them so distinctly from the other families of ducks: they are certainly of great use to them when on shore and stationary, their position being necessarily upright, the legs being placed far backwards. We should also suppose them to be connected with their motion in the water while diving, perhaps giving them the power of raising or lowering themselves suddenly. If it should he eventually ascertained that fish constitute any considerable portion of their food, this power must be of great use to them, as well as to the cormorants, in following their prey through the water.

The genus Callichen posesses two bulbs, but the skeleton does not approach so nearly as that of the two genera before mentioned. The Gizzard internally with a large cavity. To the Erismaturine we suspect the affinity is not so great, certainly not so far as relates to external character, although we have placed them contiguous, there being evidently a double point of affinity to the Divers.

Mr. Stephens, in vol. XI. p. 156, of Shaw’s Zoology, divides this genus, separating from it the Smew (Mergus albellus ), and placing the other Mergansers under the genus Merganser, Briss. The depth of the keel to the length of the sternum in this genus is as 1 to 5. Breadth of the pelvis to its length as 1 to 25. Length of the cranium to its depth as 1 to 34. Length of the femur to the length of the tibia as 1 to 17. We have spoken before of the affinities of this genus under the head of the sub-family Mergine. MOT es SYNOPSIS SPECIERUM.

Inhabits New Holland, and utters a shrill whistling note. Mr. Yarrell, in vol. 15, p. 383, gives the following anatomical pecularities of this bird. The trachea “ was situated on the outside of the left pectoral muscle, under the skin, sufficiently raised under the wing that respiration would not be impeded when the bird rested with its breast on the ground, the parallel tubes being firmly attached both to the muscle and the skin by cellular tissue. The clavicle on the right side of the bird is of the usual character, but that on the left is both shorter and wider, having an aperture about the middle, the sides diverging, with a projecting point on the inner side, to which the tube of the trachea is firmly attached about two inches above the bone of divarication. The trachea lying on the left side of the bird, the lower portion of the tube, in its passage to the lungs, crosses the left branch of the furcula at a right angle, but becom- ing attached to this projection of the clavicle, receives from the point described its centrical direction into the body. The whole length of the windpipe in this bird is four feet eight inches.” Ina young bird dissected by Mr. Yarrell, the trachea was not nearly so much convoluted. Frnteds by Citar dd. LCE Ad adhe.

Inhabits New Holland. In the Zoological Proceedings for January 25, 1831, we find the following: Mr. Yarrell stated, that having examined the body of the bird, he had remarked that its trunk was much shorter than that of the true geese, and more triangular in its shape; the pectoral muscles were large and dark coloured ; the trachea was of large and nearly uniform calibre, without convolution, and attached in its descent to the right side of the neck, as in the heron and bittern ; in the form of its bone of divarication and bronchiee it most resembled the same part in the geese. The muscles of voice were two pairs, one pair attached to the shafts of the os fureatorium, the other to the inner lateral surface of the sternum. The lobes of the liver were of large size, morbidly dark in colour ; their substance broke down under the finger on the slightest pressure. The stomach, a true gizzard, was of small size as compared with the bulk of the bird. The first duplicature of intestine was Six inches in length, at the returning portion of which the biliary and pancreatic ducts entered ; from thence to the origin of the cca four feet six inches; the czeca nine inches each; the colon and rectum together five inches: the whole length of the intestines was seven feet five inches. The stomach and intestinal viscera were loaded with fat; the other parts exhibited nothing remarkable. Internally this bird, which was a male, resembled the true geese, but externally, in the character of the bones, particularly in the rounded form of the edge, and great depth of the keel of the sternum, and the lateral situation of the trachea in reference to the cervical vertebrae, it was decidedly similar to the Ardeide.

Inhabits the southern extremity of America and the Falkland Isles; found generally in flights, according to Lesson; though we are informed by Charles Darwin, Esq. that it is generally found in pairs. The changes which the plnmage of the female of this speeies undergoes are very extraordinary. With those of the male we are at present ignorant, as to whether it assumes the white state at once or not. The young female, which is the Anas Picta of authors, first in its approach to the adult state, has the black bars on the back and neck, which become ferruginous; those on the flanks become darker, and the intermediate spaces white; the head also becomes ashy grey, and the legs approach to deep orange. Before the time of incubation black bars again appear on the neck, breast, and the upper part of the back, and the ferruginous colouring becomes lighter; the vent and under tail coverts are in very old birds white; in younger ones ferruginous, the legs become of a brighter orange, and the head and neck become brown. Such are what we believe to be the changes of this bird: for material assistance in its investigation we are indebted to Charles Darwin, Esq. and also for the trachea from which our figure is taken. The inferior larynx is furnished with a hollow rounded bulb, very similar to that of the common widgeon, but differing in its form, being flattened superiorly, and of a much stronger structure than is usual among the wading ducks. It may at once be distinguished from all the other tracheze with which we are acquainted, by an indented line on the lower surface of the bulb. (Vide our plate. ) 84 BERNICLA ANTARCTICA. Ber.

A good plate of the female will be found in the “ Voyage dela Coquille.” It inhabits South America and the adjoining islands, frequenting the sea coast and the lowlands adjoining, from whence it is called by Mr. Darwin, in his amusing Journal, the Lowland Goose. For the trachea from which our figure is taken we are indebted to the above-named friend. The bulb of the inferior larynx is not flattened above as in the last bird, but altogether bears considerable resemblance to it and the wading ducks, from which latter, in common with all other geese, it may be distinguished by the rings of the trachea being more massive, and also by the form of the tube, which is always contracted towards the inferior larynx, while in the wading ducks it always expands in that part. The flesh is not good food. Skins of both sexes are in the museum of the Zoological Society, brought home by Capt. King. 85 BERNICLA RUFICOLLIS. Ber.—Vertice colloque posteriore atris; gemis 1ufis.

Several specimens have been killed this winter (1837-8) both in Scotland and England, from flocks varying in number from seven to thirty.

The trachea of this species during youth penetrates the keel of the sternum in a similar manner to that of C. ferus, but may always be distinguished by the greater length of the bronchi. As the bird approaches maturity the tube at the internal extremity of the portion penetrating the sternum takes a horizontal twist, increasing in size and the depth to which it penetrates with age. The tube of the trachea is acted upon by two pairs of muscles, the first pair sterno-tracheal, the other having their attachment on the membrane stretched between the rami of the os furcatum and the sternum.

Dr. Richardson, in the “ Fauna Boreali Americana,” says that “ this swan breeds on the sea coast within the arctic circle, and is seen in the fur countries on its passage only. It makes its appearance among the latest of the migratory birds in the spring, while the Trumpeter swans are, with the exception of the eagles, the earliest. Capt. Lyon describes its nest as built of moss peat, nearly six feet long, four feet and three quarters wide, and two feet high exteriorly; the cavity a foot and half in diameter, the eggs brownish white slightly coloured with darker tints.” CYGNUS BUCCINATOR.

It breeds as far south as lat. 61, but principally within the arctic circle, and in its migrations generally precedes the geese a few days. A fold of its trachea enters a protuberance on the dorsal or interior aspect of the sternum at its upper part, which is wanting in C. ferus and C. Bewickii.” It is to the Trumpeter that the bulk of the swan skins imported from Hudson’s Bay belong. 10] CYGNUS ANATOIDES.

We had an opportunity of dissecting this bird through the kindness of the Earl of Derby, who had a pair alive for some time. The trachea and inferior larynx is that of a typical teal. _ It may, however, be distinguished from that of Q. crecca (which it in other respects resembles) by the bulb being more oblique, and swelling more in an upward direction. The tube of the trachea in both sexes is acted upon by two pairs of muscles of voice, the first pair the usual sterno-tracheal ones ; in the female the second pair diverge from the tube, where it penetrates the cavity of the chest, and are inserted into the membrane stretched between the rami of the os furcatum and the coracoids. In the male they diverge similarly, and are inserted in the rami of the os furcatum, haying also a slight attachment along the internal surface of the membrane stretched between the rami of the os furcatum, which is not the case in the female.

The specimen from which the above description was taken is in the museum of the Zoological Society, and was obtained from the Straits of Magellan; they also inhabit the Falkland and Staaten Islands. We have considerable doubts as to the propriety of making this and the preceding distinct species. Both are destitute of the powers of flight, merely using their wings to flapper over the surface of the sea. They are also bad divers, obtaining their living almost entirely by breaking shell-fish along the water-mark: hence the head is so strong, that Mr. Darwin informs us he had great difficulty in breaking one with his zoological hammer. The tube of the trachea much resembles that of a true pochard; the inferior larynx approaches, however, nearer to that of those geese which have bulbs on that part than to any other form with which we are acquainted; consequently also to the wading ducks, from which it may be distin- guished by being much stronger.

A native of the northern regions, but migrating southwards during winter down the European U 146 continent; breeds, like its congeners, on the coast in northern latitudes, making its nest near the water mark of grass, sea weed, and other rubbish, and near the time of hatching lines its nest with down from the body ; lays from six to ten white eggs. The trachea is very dissimilar from that of the two following species, having no bulb below the glottis, and the tube only enlarged to about twice its usual diameter in place of the inferior bulb; the inferior larynx is similar to that of its congeners. The trachea of the female is similar to that of the male, but not quite so much enlarged; both sexes have the bronchie large, and the tube acted upon by two pair of muscles, situated as in the velvet scoter.

The female of this species may be distinguished from that of O. nigra, which it somewhat resembles. by the superior length of the bill, and by the grey marking on the cheeks behind the eye, that colour in the above-mentioned bird being confined entirely to the throat. The following is Wilson's description of the trachea and anatomy of the bird: “ On dissection the gullet was found to be gradually enlarged to the gizzard, which was altogether filled with broken shell-fish. There is a similar hard expansion at the commencement of the wind pipe, and another much larger about three quarters of an inch above, where it separates into the two lobes of the lungs; this last was larger than a Spanish hazel nut, flat on one side and convex on the other; the protuberance on each side of the bill communicated with the nostrils, and was hollow.” This description agrees with that of the rest of the genus in general character.

On the commencement of incubation the males, like those of the eider, form themselves in large flocks and desert the females. The trachea of this species is very curious: it has two bulbs on the tube, the lower one com- posed of tracheal rings firmly ossified together; the upper one, situated immediately below the glottis, instead of being composed like the lower one of tracheal rings, is separate from the trachea, which passes through it, communicating with it by an orifice on each side. The inferior larynx, unlike the diving ducks in general, is not bulbous; the trachea is acted upon by two pairs of muscles, the first the usual sterno-tracheal ones, the other (furculo-tracheal) have their attach- ment a little before the middle bulb. For a figure of this see Vol. 15, Part 21, of the « Linnzean Transactions,” illustrative of a passage by Mr. Yarrell on the organs of voice in birds, and our own plate. SOMATERIA SPECTABILIS. Som.

Found most plentifully on the western side of the American continent, but occasionally also on the eastern. Nothing is known of its nidification. Wilson gives the following description of the trachea: «* The windpipe of the male measures ten inches in length, and has four enlargements, viz. one immediately below the mouth at the interval of an inch; it then bends largely down to the breast bone, to which it adheres by two strong muscles, and has at that place a third expansion ; it then becomes flattened, and before it separates into the lungs has a fourth enlargement much greater than the former, which is bony and round, puffing out from the left side. The bill of this species differs much in form from any in the family, being broad and thin at the tip, and having the lamellz more elongated. 152 CALLICHEN CARYOPHYLULACEUM.

Inhabits the eastern portions of the north of Europe, and migrates to the Caspian Sea, to Hungary, Austria, and Turkey, and the great lakes of Switzerland; never found on the sea. Such is the account Temminck gives of the bird before us ; and we are not aware that any thing besides is known concerning it, either as regards its breeding places or nest. Col. Sykes says it is rare in the Deccan. The trachea of this species has the inferior larynx similar to that of the true pochards; the tube, however, differs much, having two flattened bulbs as in the Merganser ; the inferior one is placed nearer to the inferior larynx than in the genus Mergus.

According to Dr. Richardson, this bird breeds in the fur countries from the 50th parallel to their most arctic limits. They arrive in the United States about the middle of October, frequenting the bay of Chesapeak, the sounds and bays of North Carolina, and the coast of Mexico. The canvas- backed duck may be distinguished from the following at once by its greater size and the superior length of the bill; it is said to be most delicious food. Of this, however, we have considerable doubts: none of the other species contained in this genus or even among the Fuliguline are so. FULIGULA FERINA.

We have also received it from India. The sea appears to be its true habitation, but it is occasionally found frequenting fresh water, par- ticularly in the breeding season, when it makes its nest on the borders of rivers, laying twelve eggs of a greenish white colour, and generally within the arctic circle. The trachea of this and the two following species are so very similar that it can be only by a comparative description that we shall be able to make their distinctions understood. All have the tube of the trachea largest a little below the glottis; it is slightly contracted about one-third of its length from that part, again expanded, and again contracted immediately above the inferior larynx. The bulb in all is flattened, and mostly membrinaceous, with merely just sufficient bone to stretch the membranes or tympanum. Two of the species, I’. cristata and F. ferina, have a second swelling or small bulb entirely osseous on the right side, composed of enlarged rings of the lower part of the tube, through which the bronchia of that side passes; this bulb and the whole of the tracheal apparatus is smaller, as well as the tube shorter, in F. cristata than in F. ferzna. The trachea of F’. marilla may be distinguished from the preceding by the inferior larynx being destitute of the bulb on the right side; in other respects it is similar. FULIGULA AMERICANA.

We have, however, examined a very large number of specimens, and find the following distinctions to hold good both in young and old birds. The bill in the present species is shorter than in F. ferma, the nail broader, and the whole bird rather larger. In form the nail is much more rounded at the sides, the bill more rounded immediately above the nostrils, and not so deeply channelled in the centre; also broader measuring across the culmen.

Scaup Duck of American authors. Fuligula affinis nobis. Inhabits North America. This is another bird of which we have entertained considerable doubts as to the propriety of making into a species: the above distinctions, however, appear through all the specimens we have examined to be constant. It is a curious fact that most of the water ducks* ( Fuliguline ) of North America and Europe should be all distinct, while those land ducks (Anatine) and the mergansers (Mergine ) should in a great measure be identical. We can only attribute it to their being en- dowed with a greater power of wing, and to the former (Fuliguline ) following the sea coast in their migrations, and probably performing it by shorter flights, consequently being less liable, if I may be allowed the expression, to lose their road. It is, however, yet a question whether, if the theory we have advanced in the introductory chapter of this work prove true, they will not eventually take the rank of varieties. * We have never examined the eiders of North America. 158 FULIGULA RUFITORQUES.

This species was found by Dr. Richardson in the fur countries during winter ; they frequent the rivers and estuaries of North America. The above bird appears to hold an intermediate station between F’. cristata and F. marilla— the crest is smaller than in the former, and larger than in the latter. The female may be distin- guished from the female of the latter by the greater extent of the triangular space at the upper part of the base of the bill, and from that of Cristata by its larger dimensions. 159 FULIGULA CRISTATA.

Rare as the occurrence of this bird is in the British isles, it is not uncommon in some parts of France, Holland, and Germany, and is found also in India and North America. Mons. Temminck informs us in his Manual that it constructs its nest by the sides of rivers and morasses, laying eight or ten white eggs slightly tinged with greenish. The form of the tube and inferior larynx in this species will be best understood by consulting the plate. It is acted upon by two pairs of muscles, the first the usual sterno-tracheal ones, the others furculo-tracheal. It differs from that of the foregoing genus in having the tube much more enlarged.

Breeds in the arctic regions, but regularly migrates southwards during winter; is found commonly in Europe, frequenting both fresh and sea water, but more commonly the latter; during the breed- ing season, however, they are stated by travellers to frequent exclusively fresh water, making their nest on the shores of lakes and rivers in the fur countries, and laying from seven to ten white eggs. The trachea has a large contractile bulb on the tube; the inferior larynx is not very dissimilar from that of the Mergansers ; the tube is acted upon by two pairs of muscles of voice, the first of which are the usual sterno-tracheal ones, the second pair (which are furculo-tracheal) diverge from the tube at a little distance below the contractile bulb, and have their insertion on the rami of the os fureatum near the middle of each.

Breton, R.N. inserted in the Zoological Proceedings for 1834, p. 19, from which we extract the following: « He (Lieut. Breton) stated that these birds are so extremely rare that he saw only three of them during his various excursions, which extended over twelve hundred miles of country. He has never heard of any instance in which more than two were seen together. They are only met with on the rivers and in pools left in the otherwise dry beds of streams. It is extremely difficult to shoot on account of the readiness with which they dive. The instant the trigger is drawn the bird is under water.” ERISMATURA MACCOA.

During winter, in hard weather, these birds migrate southwards, and are found over considerable portions of the continents of Europe, Asia, and America. We have also received them from Peru. The trachea in the male has two enlargements on the tube, each of which are compressed, and composed of alternating semi-lunar plates.

Rare in Europe; one or two specimens have, however, been killed in the British isles. North America is its true habitat, over the whole of which it appears during winter to be found ; as spring approaches, the greater portion of them retire to the north, though some remain and breed in Pennsylvania, Kentucky, and the intermediate district. It builds in holes of trees and rocks where it can find them; but in districts devoid of such localities builds on the ground on the borders of lakes, laying from six to ten white eggs.
