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 Fasciculus 

 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 Hundred 

 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 all 

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



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

 log}-, in which the Ammals have been introduced, and is sold at a price not a third of others which do not contain a 

 half of tlic 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 vcrj' handsome volume, alike creditable to the facile pencil of Captain Brown, and the matchlen burin 

 of Lizars. The volume contains no less than d3 plates, embracing 135 neio species, and in all 1156 figures. Of the exquisite manner in which the 

 Shells are 6nished, we feel it impo:>«ible to convey an adequate idea; could we transport one of these splendid delineations to our columns, we should 

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



"While there arc talent and accuracy in the Drawings, we need hardly say that Mr. Lizars has executed the cnpraving department in a tasteful 

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

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



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

 poneases. 



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

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

 minute species. The second work is, ' Uono\-an's British .Shells,' in octavo, published also in 1803, containing only 184 species, principallj- the lar|^e 

 shells — engraved in a stilT and slif^ht manner; price X7. 15s. So that it requires both these works to be possessed of all the Shells known even in 

 their time — the joint price amounting to Xl4. is. — and then you have only the small number of 389 species, and these very indifferently done. 



"Brown's Illustrations are fold at JC6. 168. 6d. The Eogravinge are highl;/ finished, and, as we have said, beautifully coloured. The volume 

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

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



This Work, originally published at £6. I6s. 6d., will now cost only £2. 5s. with Six additional Plates.
