HOBSON, WELLINGTON, SALOP. 1875. PREFACE. I have now figured, I believe, all the principal forms of the Skeletons of Birds, and in conclusion beg to thank those who have assisted me. I am much obliged to Mr. Gerrard, senior, of the British Museum, and Mr. Flowers, of the College of Surgeons, who have always assisted me in finding anything I wanted in the respective collections in their care ; to Mr. Bartlett, senior, also, I am much obliged for information regarding the habits of some birds, among which I may mention Chauna Chavaria, and Bhynochetus Jubatus ; and to Professor Owen I am much obliged by his always giving me access to him, although so much employed, when I wished to ask him a question ; to Dr. Gray also I am obliged for allowing me access to the collection under his care. I have added to this Supplement a list of plates of Skeletons of Birds for reference. T. C. EYTON, Ey ton-on-the- Wealdmoors, Wellington, Shropshire, LIST OF PLATES AND INDEX. Eurycerus prevostii.

This bird was described by Lesson in his "Centime Zoologique" in 1830. The following is a part of his description: — "I/oiseau type, du genre nouveau que nous representons clans la planche 74 est une des singularites les plus neuves et les plus remarquables de I'ornithologie. " C'est un passage transitoire entre les toucans, les calaos et les enrylaimes ; c'est un type caracterise a placer comme lieu intermediaire entre l'erotta. — (Traite d'Ornithologie, p. 260) et les buceros. " Les enryceres appartiennent a nos passereaux heterodactyles et a notre famille des enrylaimes, le genre sera ainsi caracterise/' Bonaparte, in his " Conspectus Genera Avium," classes it near the Rhamphastidre after Buceridce, which immediately precedes it. G. It. Gray classes it among the Sternidce, to which it has no affinity whatever. Cranium rounded, without any channel over the vertex to the bill. Occiput very round, with a slight depression on each side above the foramen magnum ; orbital septum, perforated with two foramina, orbits large; the superior margin slightly reflexed. Bill, with the upper mandible, large ; very much raised above, composed of cellular bone, deep ; lower mandible deep, with a foramen near its hinder extremity ; both mandibles pointed. Sternum of moderate length, with a deep and wide fissure on each hinder margin. Pelvis broad, short. Palatine bones prolonged on the exterior and hinder margin into an elongated spine, from the base of which they slope gradually, UDtil they unite in the centre, where they are slightly deflected, broad. Furculum much arched anteriorly; the process at the junction of the rami, which are rounded, arched, flattened, and the rami long. SUPPLEMENT II. B 6 BUCERID^E.] OSTEOLOGIA AVIUM. [EuRYCEROTINjE.

From the first family it differs in the shape of the sternum, and from the last in almost every part, particularly in the structure of the sternum and the palatine bones. In all these particulars it agrees with Buceros, and also in the form of the pelvis and furculum. Illustration. Sup. 2, pi. A. Details, pi. 1. CrACIDjE.] OSTELOGTA AVIUM. [OPISTHOCOMINiE. Opisthocomds. Cristatus. Cranium, a channel of moderate depth, has its origin at the base of the bill, and proceeds backwards on the top of the head to the occiput. Occipital ridge slight, and with a small occipital protuberance ; orbits of moderate size; the septum with one fora- men on its hinder and lower edge ; a transverse indentation at the base of the bill ; nostrils situated at about half its length, nearly round. Palatine bones much bent downwards ; broad for their posterior two-thirds, and united for that distance down their centres, then divaricating, and both edges turned downwards, forming a channel on their lower edges ; hinder end pointed backwards, and gradually narrowed to their junction with the interarticular bones, which are broad for their anterior half and narrowed backwards, the outer edges slightly deflected. Vomer thin. Foramen lacerum posterius very small. Lower maxillary bone curved downw ards ; broad, with a foramen near the hinder extremity of each branch. Sternum of moderate length ; posterior margin rounded, with one fissure on each side of the keel, and with a large triangular foramen on each side externally to it; hinder margin considerably broader than the anterior edge. Keel very short, extending from the hinder margin to little more than one-half of the length of the sternum ; hinder edge sloped off from the point to the hinder margin. The anterior edge sloped very much backwards to the point from the junction of the furculum ; the anterior portion being a mere rudimentary ridge. Furculum having the rami very short and straight, and uniting at an acute angle, flattened at their junction with the coracoids, and becoming more rounded towards the terminal process, which is very long and narrow ; triangular anchylosed to the rudimentary portion of the keel. Coracoids short and strong, broad at their junction with the sternum, and having a slightly raised rib down the front. Pelvis with the divisions of the vertebrae on the hinder half apparent when held up to the light ; ischiadic foramen of moderate size, oval ; obturator also of medium size, without any notch in front of the acetabulum ; ilium projecting much over the bones of the ischium ; a ridge proceeds from the junction of the caudal vertebra? up the centre of the pelvis, becoming more rounded and obscure on the anterior portion. Ribs broad and strong ; the styliform process attached for a considerable length to the hinder edge of the ribs, and not projecting so far as next rib. Scapula strong, slightly deflected, slightly expanded upwards at about half its length, rounded at its distal extremity. Wing bones strong, short; ulna and radius as long* as the humerus, anterior metacarpal bone straight, posterior one much bent, having a large space between it and the inner edge of the anterior one. Leg Bones rather slender; tibia long in proportion to the femur. Metatarsus 8 Cbacidjj.] OSTEOLOGIA AVIUM. [Opisthocominje. triangular at its upper extremity, with a channel down the front, flattened towards its lower extremity ; os calcis projecting considerably, with a very slight ridge proceeding downwards from it. A supplemental metatarsal bone projecting much backwards, not twisted on its axis, tapering and flattened upwards ; tubercles for the articulation of the feet broad ; toes long. This curious bird appears to be nearly allied to the guans, but differs from in the form of the palatine bones, the hinder margin of the sternum, and furculum. There is no Gallinaceous bird that I am acquainted with that has the hinder margin of the sternum of a similar form, the nearest approach that I am aware of to the form of the furculum is among the cracidse in C. Globocera, the process at the junction of the rami is very much elongated, but is not nearly so much so as in the opisthocomus. The rami also are curved, while in the latter bird they are straight, and the furculum, instead of being anchylosed, or united by a ligament to the point of the keel of the sternum, is anychylosed to its medial portion. ements.

Gray, in his Hand-list, places this bird next Eurypyga, from which it differs in the shape of the sternum. In Eurypya the keel is very deep, and continued to the posterior margin. In Rhynochetus it is obliterated, the former bird has a deep foramen on each side, the latter none at all ; the pelvis in the former bird is quite straight on its dorsal aspect, the latter has it much arched ; in all of which respects it agrees with Psophia.

Provisionally I have classed this bird with the Psophiadse, but there is another family with which it agrees in many respects, but without knowing anything of the habits of the Kagu, not much can be finally determined. The family alluded to is that of the Rallidse, in which Aramus scoloposeceus is' placed by Mr. Gray; it has long feet, like Rhynochetus, and the same form of sternum. The eggs of the Kagu, of which I have two, are white, spotted with brown ; while those of Posphia, Mr. Bartlett informs me are white. Nuttall says the eggs of Aramus are two in number ; Audubon that they rarely exceed five or six, but neither of these Naturalists say of what colour they are, or shape ; they are not like any heron that I know of, or those of Eurypyga, but more like those of a coot, or large rail. 18 Nat. size.

The birds belonging to the genera that constitute this family are very curious, so much so that it is difficult to say where they ought to be classed. In many respects they resemble the vultures, as in the structure of the furculum, cranium, and palatine bones and pelvis, more particularly Neophron, while in the feet they resemble the Rallidse, and in the form of the posterior margin of sternum are not like either, but the keel resembles the Vulturidae. It is no wonder therefore that they have been classed differently by authors, a few of whose opinions I shall proceed to quote. Mr. G. Gray classes the genera Palamedea and Chauna, forming his family Palamedeidse, next to the Parridse. He says they inhabit marshy places and inundated grounds, in the northern parts of America, especially those that are situated near the sea. It is generally found in pairs, and is very shy and timorous, hut soon betrays itself by its loud calls. The seeds and leaves of aquatic plants constitute its principal food. These birds are peculiar to the northern parts of South and Central America. They are observed in the marshes and occasionally on the borders of lakes and rivers, in pairs, or in troops of many individuals. Their manners are shy, but when not scared their gait is slow and stately. Their flight is easy and swift, and they are unable to run, except with the assistance of their wings. They resort to rest on the tops of high trees. The Brazilian species is kept by the natives amongst their poultry. It goes with them to feed during the day, and during this time proves very useful in defending the poultry against the attacks of the numerous birds of prey, by means of the spurs on the bend of its wings. If the wing of the bird is handled a crackling is felt, which is caused by the quantity of air which is lodged between the skin and muscles. Marsh}- and inundated places are preferred by these birds, as their food consists solely of the leaves of aquatic plants, grapes, and seeds. Their nest is spacious, and made of small branches of trees, and usually placed in a bush surrounded with water, but sometimes it is formed among reeds and rushes. The female lays two eggs. Castelnau, in his "Animaux ou Pares de 1' Amerique du sud," gives a plate (15) of Palamedae Cornuta and the sternum of Palamedse Derbyana, and (page 73) a description and account of the two birds, in which he says they are very different from the moor-hen, rails, or coots ; and Illiger unites the genera Glarieola, Cereopsis, Chauna, Palamedea, and Psophia, under the name of Alectorides, from which they are very different. He also says, in speaking of the sternum, that it presents an analogy to the Vulturidas. c; Beitrage zur Naturgeschichte von Brasilien von Maximilian Prinzen zu Weid" ; from which the following is a translation : — " I he Aniuma, from its great size and beauty, forms an ornament to the Brazilian forests. It is dispersed over a large portion of South America, for it has been seen in Guiana, where Somnini 36 Falamibeidje.] osteologia avium. [Palamedeinje. found it ; it does not however appear to be found at Paraguay, as Azara makes no mention of it- I myself never met with the bird in Brazil, until travelling from South to North I had reached the island Caxoeirinka (Kaschoerinnia) in the river Belmonte, that is to say the sixteenth degree of south latitude. I was told there that it had never been seen higher up the stream towards Minas. In the neighbourhood of the above-named island in the Belmonte it is very numerous. It only frequents lonely spots far removed from the habitations of man. I never met with it, as Sonnini describes, in open places, only in the depths of the primeval forest on the bor lers of the river, after I had made some days' journey up the stream of the Belmonte. There we frequently heard the loud, uncommon cry of this bird, which in its modulation has some resemblance to our own wood- pigeon, but it is much louder and more shrill and the throat note is pitched in another key. " Sometimes we saw the Aniumas as they strutted on the sandbanks and in and out of the river. If we approached them, they took fright, and then, both in the size and broad expanse of their wings, and in their colour and manner of flapping them, they resembled the Urubus (Cathartes Aura et Urubu). They always perched in the summit of some thickly -leaved forest tree, where we constantly heard their voices, though we could seldom see the birds themselves. In the breeding season the Aniuma pairs, at other times four, five or six are seen together ; they go to feed on the sandbanks or in the thickly wooded marshes, which are so frequent in these forests. The food of these birds appears to be entirely vegetable, at least in the five or six, whose stomachs I have examined. I found nothing but leaves of a kind of grass plant and of another broad-leaved grass plant. " The nest of this bird is found on the ground in the wooded marshes near the river. The Botocudians state that it contains two large white eggs, and consists of only one layer. The young birds run at once on leaving the shell. " The flesh of the Aniuma is not good eating ; the Botocundians devour it all the more greedily, as the Portuguese do not eat it at all. The fine long pinion feathers are used for writing, the tail feathers are much valued by the savages for their arrows. There is a popular superstition that this bird always dips his frontal horn into the water when he wishes to drink." Marcgrave calls the Aniuma a bird of prey, in other respects he describes him very correctly, and represents his voice tolerably correct by the word " Vihu, Vihu." He mentions the great attachment subsisting between the male and female when paired, but of this the Brazilian sportsmen made no mention to me. That the two sexes differ greatly in size, as Marcgrave represents, is incorrect. 1 hat the nest has the shape of an oven, must, if the state- ments of the Botocundians is to be believed, be a fable. The following note was sent to me in reply to one of mine, by Mr. Bartlett, of the Zoological Gardens of London: — " In reply to your note, I find the Chauna and Palamideidse feed upon green food principally ; they will also eat boiled rice, bread, and boiled Indian corn, but no flesh of any kind." — " Yours faithfully, A. Bartlett." 3T PALAMIDEID.E.] OSTEOLOGIA AVIUM. [Palamedetn^e. Pala medea, Lin. Cornuta, Lin.

I have received a skeleton of this bird, which differs so much from the figure in the " Zoological Transactions," that I should almost think there must be two species of Great Auk. Mr. Ed. Gerrard, from whom I received my skeleton, gives this account of it: " You may perhaps like to know how I got these bones. They were got from a guano island off the North of Newfoundland. A vessel was sent there to see if the guano was worth anything for manure. It was found to be useless, owing to the island being so washed by the sea that all the nature was washed out of the guano. While digging about, one of the gentlemen came across a quantity of bones, which he took to Mr. Woodward, of the British Museum, and they turned out to be the bones of the Great Auk. I bought the whole, and after spending a great deal of time in sorting them over, I have been able to make out three tolerably perfect skeletons, the best of which I have given you the refusal of."
