Illustrations of the recent conchology of Great Britain and Ireland, with the description and localities of all the species, marine, land and fresh water

Yl 1' lt E F A C H . . greater extent than might be desirable to those who studied the shclls alone ; he therefore reservecl the figures and descriptions of the Animals for a separate treatise, wh ich will appear uniform with the present vVork. This arrangement, it is hoped, will prove more satisfactory to both parties. He has, however, given two plates of Land and Fresh ·water Mollusca the size of life. The representations of the interesting genus Limax, are copied from beautiful and correct drawings kindly furnished by the Rev. B. J. Clarke, of Tuam, Ireland, who has Iately bestowed much atteníion on, and ably investigated the Limacidre of his native country. Authors have admitte<l into the British Catalogue, species whi.ch are not indigenous; these have been omitted, but such as appeared in the First Edition of this work have been allowed to remain on the plates, the names only being given without descriptions. Every shell, as far as possible, has been drawn from Nature, and generally from the largest and most beautiful specimens which the Author could meet with. But sorne of the smaller species, whose existence rests on the authority of Walker and A<lams, he has been obliged to copy from their works, an<l therefore <loes not hold himself responsible for their accuracy. In recording the names of those to whom the Author is indebte<l for aid in the following Work, be must particularly notice those of his late lamented friends Dr. Leach, formerly Chief Zoologist in the Brit ish Museum, and General Hichard Bingham, of Melcombe, Dorsetshire. The first of these, with that noble liberality for which he was prominently distinguished,-although engaged with a similar work at the time the Author was preparing his First Edition,-threw open his treasures for his use, and otherwise aided him as far as possible in his investigations. To the latter the British Conchologist, and himself in particular, are deeply indebted for the discovery of many new minute species. He spared neither trouble nor expense in following up this branch of Natural History. It will also be seen how much his valued and early friend Stewart Ker, Esq., has a<lcle<l to thc Mollusks of the Cly<le, an<l he must also cordially acknowle<lge his obligations to his friends James Smith, Esq., of Jor<lan Hill, near Glasgow; Professor Forbes, King's College, London; James Gerard, Esq., Edinburgh; Sir Oswald Mosley, Bart.; vV. C. Trevelyan, Esq., of Nettlecombe Abbey; Thomas Glover, Esq., of Smcdley Hill, Manchester; William Nícol, Esq. , Edinburgh; William Bean, Esq., Scarborough; Lieutenant William Beaumont, R. N., for specimens of Lymnrea involuta; and to Miss Thomson, of Kendal : and for information on lrish Conchology, to his old friend and fellow-labourer in Conchology M. J. O'Kclly, Esq., Rochestown House, County of Dublin; Robert Ball, Esq., and rdiss Mary Ball, Dublin; Thomas William Vlarrcn, Esq., of Dublin, who possesses the best collection of indio-enous shells .
