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 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 a 

 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 Brown, and the matchless burin 

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

 Shells are finished, we feel it impossible 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 are talent and accuracy in the Drawings, we need hardly say that Mr. Lizars has executed the engraving 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 w..rk, 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 

 possesses. 



" The two best works which we have on our native Conchology are, first, ' Montagu's Tcstacea 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 is £6. 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, principally the larg^e 

 shells — engraved in a stiff and slight manner; price £~. 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 .£14. Is and then you have only the small number of 389 6pecies, and these very indifferently done. 



"Ibouii's Illustrations are sold at £6. 16s. 6d. The Engravings are highly finished, and, as we have said, beautifully coloured. The volume 

 of 53 elegant quarto plates, containing 1 156 figures of Shells, 135 of which are entirely new, and never before published; besides 148, which 

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



g^* - This Work, originally published at £C>. KJs. 6d., will now cost only £2. 5s. with Six additional Plates.
