ILLUSTRATIONS OF THE CONCHOLOGY 

 OF GREAT BRITAIN AND IRELAND. 



BY CAPTAIN THOMAS BROWN, F.L.S., &c. 

 SECOND EDITION, WITH ADDITIONS. 



1. Each Number will contain Four Coloured Plates, with complete Descriptions, Localities, &c. A FasciculusJ 

 will appear regularly every month. Price Three Shillings Coloured, or Two Shillings Plain. 



2. The Work will extend to Fifteen Numbers, containing in all Fifty-eight Plates, with about Twelve Hundre 

 Figures of Shells, being Representatives of ALL the Species discovered up to the present time, including Marine 

 Land, and Fresh Water; together with Illustrations of the Animals of nearly the whole Genera. The Plates are ; ' 

 already engraved by Mr. W. H. Lizars, so that the Work will appear with the utmost regularity. 



3. This is the only Work which contains Representations of ALL the Species, and the only British Concho 

 logy, in which the Animals have been introduced, and is sold at a price not a third of others which do not contain i 

 half of the Species, while the Engravings are executed in a much higher style of art. 



Opinions of the Press on the First Edition. 



" The Work is now completed, and forms a very handsome volume, alike creditable to the facile pencil of Captain Bron-n, and the matchless buti 

 of Lizars. The volume contains no less tlian 53 plates, embracing 135 new species, and in all 1156 figures. Of the exquisite manner in which tb 

 Shells a^ finished, we feel it impossible to convey an adequate idea; could we transport one of these splendid delioeationB to our columns, we shou*^ 

 require no words to enhance its value." — Observer. 



" While there are talent and accuracy in the Drawings, we need liardly say that Mr. Lizars has executed the engraving department in a tastefi 

 and able manner. The colouring is here so much elaborated, and so judiciously managed, that the specimens have many of the beauties of puintinfj 

 and this work, we imagine, will go fur to make the public think more highly of the Shells of the British Isles." — Scotsman. 



" A alight glance at other works on the same subject, will be the best mode of showing the superior claims to attention which the present voluni' 

 poauaes. 



"The two best works which we have on our native Conchology are, first, ' Montagu's Testacea Britnnnica,' quarto, published in 1803. It only 

 contains 205 species, drawn and etched by a lady, and very indifferently executed ; the price of this work is £(>. 6s. The Shells represented are mostly 

 minute species. The second work is, ' Donovan's British Shells,' in octavo, published also in 1803, containing only 184 species, prinripaUy the largo 

 shells — engraved in a stiff and slight manner; price X7. 16s. So that it requires both these works to be possessed of all the Shells known even iii 

 their time — the joint price amounting to £\4. Is. — and then you have only the small nimiber of 389 species, and these very indifferently done. 



"Brown's Illustrations are sold at jE6. 16s. 6d. The Engravings are /iij/i/y _^nis/i<;(f, and, as we have said, bciutifiilly coloured. The volume 

 consists of 53 elegant quarto plates, containing 1156 figures of Shells, 135 of which are entirely new, and never before published; besides 148, »liirh 

 have only appeared in the Transactions of different learned Societies." — Edinburgh Evening Post. 



tg" This Work, oriijinally piiblishod at £G. I6s. 6d., will now cost only £2. .5s. with Six additional Plates.
