Book Description
Excerpt from The Quarterly Journal of Conchology, Vol. 1: August, 1878 On looking over my notes and Journals made during many years devoted to Conchological researches in the various South Sea Islands, I have selected and tabulated the following list of Cones collected in all parts of Polynesia, hoping it will not be devoid of interest to those engaged in elucidating the difficult problem of the geographical distribution of the mollusca. It is worthy of remark that every species mentioned in the present list has been collected by the writer, so that the locations and range of each can be relied on as correct. Of course further research will increase the number of species, and prove that others have a more extended range than given in this Catalogue. I have not attempted to elucidate the cause of variation, which, in many cases, is as great in the same group of Islands as in those species common to remote localities. Shells inhabiting Western Polynesia are most generally larger and firmer than Eastern Polynesian examples, but in some instances the contrary takes place.

Excerpt from The Quarterly Journal of Conchology, Vol. 1: May, 1874 Journal to give from time to time outline sketches of abnormal forms under recognised varietal names - given by such eminent authorities as Jeffreys, for instance - it would be very valuable and interesting, especially to the student subscribers of this interesting Journal. In the foregoing remarks I have but alluded casually to the varia tion of the animal which inhabits the shell, which doubtless varies more or less in conformity to the variations in the shell, either in some particular organ which regulates colour or texture or general form combined; but as these particulars are not mentioned by authors genei ally, except such variation as relates to colour in the animal, we may infer that difference in the shell is chiefly recognised in the naming of varieties of such that are shell bearing. The fact that when any difference 111 form is made apparent in any particular organ or combination of organs in the animal which inhabits the shell, it is then placed upon debatable ground as to its rank as species or variety; this shows how important variation in form is to be considered in relation to other varietal differences.

Book Description
Excerpt from The Journal of Conchology, Vol. 7: Established in 1874 as the Quarterly Journal of Conchology The conclusion of the seventh volume of the 'Journal of Conchology' terminates the connection which I have held as its Director and Editor for the long period of exactly twenty-one years. The journal was originally commenced as the 'Quarterly Journal of Conchology' in February, 1874, at a time when the science of Conchology was at a very low ebb in Britain, its students few, scattered, and disorganized, and as a necessary consequence the publication of the work was for years after its inception only carried on by steady sacrifices of time and money. Such sacrifices as were necessary I however cheerfully made, and the publication was persevered with in spite of manifold discouragements and against the advice of many kind and true friends, who looked upon a financial return as the crucial test for all projects, scientific or otherwise. In process of time, however, the exertions and sacrifices I made begun to take effect, more and more interest was taken in the study, and the students and subscribers increased in numbers. One of the first practical results of this revival was the establishment in 1876, by four Leeds conchologists (Messrs. H. Crowther, W. Nelson, W. Denison Roebuck, and myself) of the Conchological Society. The society when formed gradually increased around this little local nucleus, until at the present time it is quite a powerful organization, though there are still large numbers of students who have not yet allied themselves with us. The vigour and ardour with which conchology is now pursued, and for which happy result the journal may surely claim much of the credit for having fostered and encouraged, is amply and convincingly evidenced not only by the successful establishment of conchological societies in London and Manchester, but by the recent publication of another journal, solely devoted to the subject, which journal I understand is and has been from its commencement a successful financial undertaking, the originator and editor of which periodical himself imbibed his love of conchology in Leeds.

The South British type, confined within a well - marked range along the southern and south-western coasts of England; eighteen out of twenty-two. III. The European type, represented by species that are equally diffused and abundant in most parts of the British seas; all out of the forty-three. IV. The Celtic type, a group especially characteristic of Great Britain, many of its members being of ancient origin and well known in the fossil state; thirty-nine out of forty-three. V. The British, an assemblage of species little known elsewhere or even quite unknown out of the British seas. Of the seven species cited as representatives of the British type, being most abundant in Great Britain, and well known in a few localities elsewhere, Dorsetshire claims five.

Excerpt from The Quarterly Journal of Conchology, Vol. 1: November, 1874 The localities referred to in this list lie within about four miles of Erith, all on the Kentish side of the river Thames. Erith itself, or Dartford, are very convenient localities for collectors living in London to visit, being within easy reach by rail. The soil about Erith is a series of sands, gravels, and clays belonging to the London clay or Eocene formation; while at Dartford the chalk crops out. Several of the species recorded are confined to the chalk. They will be noted in the list. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Quarterly Journal of Conchology, Vol. 1: May, 1877 The descriptive part follows, every species being described - both animal and shell - followed by information as to its station, and its distribution both within and outside of Germany. The synonymy is purposely shortened as much as possible, only the citation of the original description, references to some figures, and to any published accounts of the anatomy, with one or two other quotations, being given. Each species is illustrated by a. Woodcut, giving a view of the shell from above, fiom below, and sideways.
