The descriptions of Dr. Latham, and the compilations of Dr. Shaw on the various species of Toucans, are so confused, and their synonyms so inaccurate, that it is quite impossible to quote them in reference to this bird; but which I am informed has already been distinguished by the celebrated Illiger as a distinct species, under the name here adopted.
Independent of colour, this differs fromR. Tucanusin having the bill less curved, the top convex and obscure pink, not flat and blue. The belt at the base is always vivid blue (grey in the dead bird), not, as inR. Tucanus, of a rich yellow. This I have never met with in Brazil; the other is common from lat. 8 to 23° S. A drawing from the live bird by the late Sydenham Edwards (obligingly lent me by Lord Stanley) confirms others I have seen as to the colour of the bill, orbits, &c. It varies, however, in that of the throat, breadth of the red band, and in the tail-covers. A specimen I possess being somewhat larger, the breast is nearly white, and the upper tail-covers sulphur. In young birds the white on the sides is tinged with grey. I am inclined to consider theGrand Toucan à ventre rougeof Vaillant as a mere variety, having the red pectoral bar very broad.
In general size it is rather larger than the Brazilian Toucan. Our figure is on the exact scale of four-tenths to an inch. Its precise locality I am unacquainted with. We hope to enlarge more on this interesting genus in another publication.

This is one of the most natural genera in the modern systems of conchology, as it includes all fresh-water bivalves having two rough cardinal teeth in one valve and one in the other. The colours of all are more or less dark-brown, sometimes radiated with green; but the specific characters rest on the contour of the shell and the proportion of the teeth.
There can be no doubt this shell is theUnio nasutusof Say, who refers to the figure of Lister. TheUnio nasutahowever of Lamarck I apprehend will be found different, as he seems to think; his shell also is purple inside with short thick teeth; indeed so much uncertainty hangs on the shells of this genus, that the species can only be fixed by ample descriptions and very correct figures. The figure is from a shell in the Linnæan Society's cabinet. Mr. Say says it is common in the Delaware River, North America.

A few specimens of this most delicate and beautiful shell were found by my brother, Mr. J. T. Swainson, jun. in the island of Cuba; nor am I aware of its having by any other means reached our cabinets, excepting a distinct variety which occurred in Mrs. Angus's, and is now (together with a young one of the same) in Mr. Dubois's collection. This has, in addition to the green bands on the spire, a row of bead-like cinereous spots at the base of the first and second spiral whorl; and others of a longitudinal square form on those whorls nearest the tip, which, with the inner lip, is slightly tinged with pink. The form of the shell also is shorter; but the general contour, and particularly the crenated mouth, common to both, clearly proves it can be considered only as a distinct variety. The specimen we have figured agrees with all those sent at the same time, in having not the slightest appearance of spots, though in a perfect state of preservation. The little notches on the margin of the lip are always placed at the commencement of each of the green lines; the base of the column is straight, and slightly truncated before it joins the outer lip.

The vast and little known region of New Holland has afforded us some of the most beautiful birds of this superb family, and among which the species now, as we believe, for the first time published, will stand conspicuous. It is from a fine skin in the possession of Mr. Leadbeater, and is named in honour of the late M. Barraband, the first ornithological painter that France or any other country has produced.
The tail is very long, measuring eight inches three quarters; the total length of the bird being near fifteen inches. The green which predominates over the plumage is bright and changeable, having a blueish tinge on the hind head, which is much darker and stronger on the outer margins of the quills and middle of the tail-feathers: the back and scapulars are tinged with an olive-brown; the spurious quills and their protecting covers are greenish-blue, appearing in some lights entirely of the latter colour; the inner margin of the quills and tail, as well as their entire under surface, deep brownish-black; but the tips of the tail-feathers beneath are much paler; the two middle feathers five inches longer than the outermost, and extending near two inches beyond any of the others; their extremities instead of being pointed are rather widened and rounded. Bill red; ears and space between the eye and bill green; fore-part of the head, chin, and half the neck, a clear orange-yellow, which is terminated by a narrow collar of a beautiful orange-red; the remaining under plumage pale-green; inner wing-covers darker. Legs black. The fourth, fifth and sixth quills notched at their tips.

A lovely insect, which is unfigured, and, as far as we can ascertain, undescribed by any author. It appertains to the Linnæan genusSphinx, which can be viewed (from the immense diversity and great number of the species) only as a family containing many and striking natural genera: in modern arrangement it is most nearly allied to theSesiæof Fabricius, from which, as it strikingly differs in the formation of the palpi and antennæ, I have separated it.
I have named this insect to commemorate the exertions of Mr. Abbott, well known as having furnished the materials for that beautiful work the Lepidopterous Insects of Georgia, edited by Sir James Edward Smith. And from the unpublished drawings of this zealous collector, the larva and pupa have been figured. Mr. Abbott writes that it is a rare species in Georgia, and feeds on the grape. The female differs not in colour from the male, which is here represented.

Wings black; anterior above with a central reddish band, and two white basal dots beneath; posterior beneath grey and cinereous; base black with an obsolete white line; margin black.
The marginal fringe of the lower wings in this species has a few white dots between the nerves, and the upper surface is sprinkled or powdered in the middle with blueish-green atoms; on the under surface of the anterior wings the lower part of the band is orange, the upper bright rufous; and within the black margin of the posterior wings is a large blueish spot, and two or three whitish dots on the sides of the thorax. It seems nearest allied toHesp. Celsusof Fabricius, which is only slightly described from Mr. Jones's unpublished drawings.

The under surface of this insect (a female) perfectly resembles the upper: it will approach near toHesp. Amiatusof Fabricius, which no doubt belongs to this genus.
For both these interesting insects, not to be found in Fabricius, I am indebted to the liberality of my friend Professor Klug, Director of the Royal Museum at Berlin: no note accompanied them, I therefore conclude they are undescribed, and probably inhabiting South America.

This is another of the splendid little Parakeets inhabiting the forests of New Holland; and vivid as the colouring may appear in our figure, it sinks into dullness when compared with the bird itself. Dr. Shaw was the first who described it in White's Voyage to New South Wales, where it is badly represented. It has been since figured by Le Vaillant, probably from a female or imperfect specimen, as the tail is represented by far too short, and the colours not quite agreeing with that in my collection.
Total length eleven inches. The upper plumage bright green, tinged with blue on the sides of the neck, lighter and yellowish beneath; the crown of the head sapphire or violet-blue, with a crimson belt in front, and a large patch of the same round the chin; paler spots of this colour are also in front of the neck, breast, flanks, and under tail-covers; the under wing-covers are deep crimson, as well as the inner shafts of some of the lesser covers outside; the shoulders dark blood-colour; the outer wing-covers deep-blue on the margin of the wings, gradually changing to a vivid blue, which blends with the green. Quills black glossed with violet, margined externally and internally with yellow. Tail near five inches long, the middle feathers dark rufous tipped with blueish; the rest more or less rufous at the base, and shining blue beyond. Bill and legs pale.

Of this genus, hitherto considered as possessing only a unique example, we were fortunate in discovering while in Sicily the new species now figured, and which early in the year visit the coasts near Palermo and Messina in prodigious quantities. There is no striking difference between this andA. Tobianus, excepting the extraordinary shape of the dorsal fin, which is invariably undulated and narrowed in the middle. It never grows to a size exceeding the figure, and is usually much less; while the British species is often found double the length. Like that, also,A. Siculushas the lateral line running close to the dorsal fin; for the fine line in the middle of the side, as Lacepede has well observed, is that only which connects the muscles. That author likewise mentions, that the jaws inA. Tobianushave minute teeth, but these I could never discover. The rays of the fins are, pect. 16; dorsal 56; anal 30.

This genus was instituted by Scopoli many years ago, and differs principally fromSesiaby having opaque wings, and fromThyreusby the very great difference in the construction of their antennæ. Many exotic species are known, but only one is found in Europe (Sphinx stellatarumof Linn.), which likewise inhabits our own country, and to which this our insect is very nearly allied.
Though by no means uncommon in collections, I cannot find this species either figured or described, nor indeed am acquainted with its locality. The under figure is of the male; the upper of the female; which differs only in the wings being rather broader, and in having one segment in the body less than in the other sex.

The Girdled Cone is conspicuous among the beautiful shells of this extensive family, by the broad and rich chesnut bands, which are either two or three in number, and more or less broken into spots; in high-coloured shells the minute lines of dots between them are also of the same colour. It is not a common species, and inhabits the Asiatic ocean.
This is theConus Magusof Gmelin and Martini, and of our sale catalogues: this error has originated from Gmelin having described two distinct shells,C. AugurandC. Magus, under the latter name.

We have had much difficulty in the investigation of this species: for its characters cannot be reconciled with any of those contained in Lamarck's Monograph of the genus in theAnnales du Museum. With regard to the unnamed figures in the old authors, it bears the closest resemblance to that ofGualtieri, tab. 32. G, which Lamarck quotes for hisM. crocata; but then his description is not at all applicable to our shell; and Mr. Dillwyn's synonyms of the LinneanV. nodulosa(where he has also includedM. crocata), we are satisfied comprises two or even three distinct shells.
This was named by Dr. Solander from the specimen in Mr. G. Humphrys's collection here figured: it is exceedingly rare, and its locality unknown. In form it resembles aBuccinum; the transverse grooves are broad, strongly defined, and have large and deep excavated dots within them; the upper part of each whorl has an appearance of irregular plaits, which makes the suture uneven, and takes off something from the smoothness of the lower part of the whorls, but the shell is in no way granulated.

This (a common shell) can be no other than theM. ferrugineaof Lamarck, though neither that author nor any other has noticed its primary distinguishing character, that of the uncommon thickness of the outer lip at the margin, which is also divided into convex obtuse crenations; in young shells this is not apparent; such is Martini's figure. Mr. Dillwyn has changed Lamarck's name toVitulinafor this, and given the name ofAbbatisto the variety more lengthened, figured by Chemnitz; but which, from specimens now before us, we consider with Lamarck only as a variety, possessing all the essential characters here given to both.
