“ Geology, a subject hardly thought of in this country a few years ago, is now found to be a science of the first importance; with this, however, Conchology is so intimately connected, that without a certain knowledge of it, the geologist is frequently unable to prosecute inquiries of the most interesting nature; and there is little doubt but that Botany has been raised to the rank it now so justly holds, solely because its natural system has been more generally studied and advocated in this country, than that of any other branch of Natural History. ”

“ Why, that Paris has become the Zoological university of Europe; and that the principles which have emanated from it, are now considered the only true ones by which Nature is to be studied.
It is not my object to attach reproach to any body of men collectively, or to any one individually; but truth is not to be concealed. Every writer who has the advancement of his favourite study at heart, is bound (however feebly) to advocate its cause. ”

“ I consider, therefore, formation and sculpture as the only certain characters of species, and that variation of colour should alone distinguish varieties.
It is therefore not surprising that the specific characters given by MM. Bruguiere and Lamarck, and resting principally on the colours of these shells, are frequently obscure, and always long; two inevitable evils attending every attempt to describe minutely the colour, form, and disposition of the markings of shells. ”

“ A pretty and diminutive species, scarcely ever more than one inch three lines long. The spire long in proportion, and occupying half an inch: when in perfection the colour is a deep chesnut, minutely broken into finely serrated darker lines, with one, two, or three interrupted bands of white on the body whorl, the spire, and margin of the outer lip paler; there are two or three nodules above; and the spiral volutions have the carinated row of tubercles usual in the Strombi, and are besides finely striated transversely. The base of the shell is more deeply and distinctly striated ”

“ In the present ignorance in which a true knowledge of the Lepidoptera is involved, it is impossible to say how far these dissimilarities may point out natural groups; it is therefore of the highest importance to the science such facts should be noticed. ”

“ I have, however, remarked, that the various modifications of the umbilicus, and the termination of the pillar (which is indicated in many species by an elevated ridge or rib within the umbilicus) is a certain and constant indication, presenting the same peculiarity through all the individuals of a species, even in the young state. This termination of the pillar has been mistaken for the inner lip, which, on the contrary, is always above the umbilicus, which, if closed, is not closed by the lip, but by the thickened termination of the pillar or columella. ”

“ At this time, there is not perhaps a single department of Zoology which is not employing the attention of more than one writer. It is to the honour, and to the lasting benefit of science, that it should be so: and although a great part of the new objects collected during my travels in Europe and Brazil have recently been made public by MM. Temminck and Godart, I feel rejoiced that this has been done by such distinguished men.
I have been induced to enter (perhaps too fully) into a general defence of Zoological miscellanies, from the opinion I entertain of their great utility. ”

“ The distinctions of Colias Pyrene as a species rest on the areola of the anterior wings being considerably larger in proportion than in the others allied to it, thus making the black dot (which is always placed at the outer extremity of the areola) much nearer the tip than the base: these wings are also more sharply trigonal (in the male) , and have only the slightest appearance of a black margin; the hinder wings are also perfectly entire, and not obtusely undulated as in those insects, and the sexes not differing in colour. ”

“ The peculiar character of the species, and in which it differs from all others, is in the outer margin of the lip; which is thin, rather spread out, and slightly reflected; the form of the shell resembles A. fasciata, but the spire, instead of being pointed, is obtuse; the umbilicus, likewise, is smaller and more concealed. From the absence of a groove round the aperture, I conclude the operculum is horny.
The size varies; perfect shells are in my possession much smaller than the figure, and I have seen others much larger, and with the aperture more chesnut than purple. ”

“ The Tinamous are entirely confined to the new world, where they seem to hold the same scale in creation which the Partridges do in the old continent. Our knowledge of these singular birds has been much increased by the writings of Professor Temminck, who has described twelve species. The present bird is nearly the smallest of its family: I found it only once in the interior of Bahia in Brazil, where it must be very rare, or frequent to particular districts only. Though differing in some respects from the description of Temminck, I am inclined to consider it merely as a variety. ”

“ From the earliest ages, the Butterfly appears to have attracted the admiration of mankind; and we find it celebrated by their poets as figurative of gaiety and pleasure, and by their sages as an emblem of the human soul. ”

“ Instruction in these days of refinement must be made easy, palatable, and enticing; the eye must be pleased, while the understanding is improved, and Wisdom in her simple dignified garb will often be deserted for Ignorance, decked out in the glittering trappings of Folly. ”

“ The shell generally known as the Ach. virginea (Bulla virginea Lin.) is so common, that few collectors do not possess it. The varieties, however, of this species are rare, and differ so remarkably in their colouring, as to require illustration. Several kindred species of this family I have already described; and on the same principle of establishing specific distinctions from formation instead of colour, I shall now endeavour to point out those characters which are common, more or less, to all the varieties of this species, and which distinguish it from its allies. ”

“ The Shells of this genus are composed of such of the Linnæan Nerits as are umbilicated, from which latter they essentially differ, both in the organization of the animal and the construction of the shell, which is either closed by a shelly or horny operculum.
The species are numerous, and are found both in temperate and tropical seas; two or three inhabit our own coasts, but by far the greater number are found in the Asiatic Ocean. They are subject to variation in their colour; and this, joined with a general resemblance in form, has rendered the discrimination of the species very difficult. ”

“ The Kingsfishers have such a general similarity of form, that the most casual observer is able to distinguish them: a very long straight bill, short wings, and (in general) a shorter tail with very small legs, are the prominent distinctions of such as are usually seen; and the richness of plumage that generally pervades them cannot be better exemplified than in our own beautiful species, the common Kingsfisher, not unfrequent in many parts of England. ”

“ I am unacquainted with the other varieties of this species mentioned by authors. Of the bird here described, I have never seen any variety, either in Brazil or in our museums. The young males, as usual before moulting, have the colours of the female; one of them, in an intermediate state, is in my possession. As both the figures are of the size of life, and accurately coloured, a fuller description is unnecessary. The rich sky-blue of the male, in some lights, becomes greenish, and in others dark blue. ”

“ If occupation or indolence does not permit one labourer to make known his discoveries, is another (who perhaps unconsciously has been working on the same ground) to hide the knowledge he has gained? This is surely a principle at once illiberal and unjust. ”

“ I see no reason why the original name of Linnæus for this shell should have been changed, although, under it, he has evidently included other species quite distinct; (his var. β being C. ebræus) : indeed, it too often happens, that in making those alterations absolutely necessary in the present state of the science, the spirit of innovation oversteps the justice due to those, whose labours first laid the foundation of our own knowledge. ”

“ The bill is one inch one line long from the gape, and, with the irides, is red. The head and neck above blackish cinereous; the crown much darker and tinged with brown, the rest of the upper plumage uniform reddish-brown; the edges of the wing-covers tinged with pale cinereous; the spurious wings and quills greyish-brown; the chin is white, changing on the throat, neck, breast and their sides to a pale lead-colour, which, on the body, again becomes white; the feathers on the flanks are blackish or rufous, beautifully margined all round by white, with another internal mark of the same kind ”

“ Above cinereous, beneath whitish; head, wings, and rump, olive yellow; throat yellowish; eyes encircled by a ring of snowy feathers.
On first receiving this bird from New Holland, I was inclined to think it a distinct species from the African White-eyed Warbler; but further consideration has led me to adopt a different opinion: it is true that I am unacquainted with any one land bird which is common to both countries, and much weight should be attached to the geographic distribution both of families and species. These two birds, however, differ in their colour, and somewhat in their size. ”

“ The celebrated Latreille, the father of modern Entomology, has well observed, that the immense number of insects crowded together in the genus Hesperia contain many natural genera, but which the paucity of species generally found in cabinets prevents us from discriminating. Having for a long time paid attention to this family, and possessing near 300 species in my own cabinet, I have had the opportunity of attempting their elucidation ”

“ Cramer, pl. 301. D.
It is in all things better to understand few subjects well than many imperfectly; knowledge may be extensive, but it cannot be sound, if it is at the same time imperfect; and, applying this observation to the present article, it becomes as desirable, where necessary, to illustrate an insect known to Linnæus, as to regard only the accession of new species. ”

“ 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 ”

“ Shell oval, minutely punctured, spire obtuse; margin of the exterior lip within, and base of the inner lip thick and rufous; operculum horny?
This and A. oblonga are the only species I am yet acquainted with, whose form is not globose. It never grows to a size much larger than the figure; the whole shell is marked by fine longitudinal striæ, and transverse lines of minute dots, discernible only by the aid of a common magnifier; the aperture within is brownish flesh-colour; the margin is strong and reddish, and, within that of the outer lip, is a thickened rim ”
