described in detail, illustrated by one or more plates of as many species 

 of shells as may be considered of interest ; whilst its origin and distin- 

 gnisliing characters, the various situations to which it has been assigned 

 in the system by different authors, and the pecidiarities of habit and 

 organization of the animals referred to it, are at the same time strictly 

 investigated. Amongst the genera adopted, are included nearly the whole 

 of those advocated by Lamarck ; the author has at the same time care- 

 fully abstained from introducing any new ones of his own, and only such 

 of those proposed by modern authors are admitted as have resulted from 

 positive discovery. 



Although the systematic arrangement of the Lepades and MoUusca 

 is displayed in about two hundred and forty genera, it has been thought 

 usefid to notice above fcRU' hundred otlier genera, introduced from time 

 to time by ^'ariovis authors, but abandoned as superfliious. At the end 

 of each volume is an index of all the genera mentioned therein, referring 

 to the pages where they are treated of; those adopted in the classifi- 

 cation being printed in Eoman type, the remainder in Italic. 



The Work is divided into two volumes ; the Urst contains the Lepa- 

 des and Bivalve Mollusks, illustrated by 130 plates of shells, and the 

 second contains the TJnivalve Mollusks, illustrated by 170 plates, in- 

 cluding in all above fifteen hundred figures of more than a thousand 

 species, many of which are entirely new to science, and of great interest 

 to collectors.

" Mr. Reeve, appears to be the first English author who has successfully accomplished the very 

 difficult task of classifjing the testaceous mollusks according to the true nature of their organiza- 

 tion and habits. His arrangement of the molluscous division of the Animal Kingdom appears, as 

 fiir as we are enabled to judge, to be a well-directed, conscientious distribution of them ; and its 

 history and characters are described in that simplicity of style which makes the study as pleasing 

 as it is full of scientific interest. We congratiilate Blr. Reeve upon having produced a perfect 

 epitome of conchological science : no one with the slightest pretension to a conchologist can be 

 without it. The new figures, which are beautifully drawn, do the artist (fllr. G. B. Sowerby, Jun.) 

 an infinite deal of credit ; and not less Mr. Keeve for the judgement displayed in selecting the 

 species for illustration, a large portion of which have never been figured before." — Polytechnic 

 Juurnitl. 



"Among the most laborious and successful labourers in this branch of science, the public has 

 to congratulate itself on the possession of Jlr. Reeve. His present work, of which the moiety is 

 before us, is an honourable proof of his devotedncss and ability. 



" To the execution of his plan we have only, in addition, to ofl"er IMr. Reeve the tribute of our 

 hearty approbation ; and we look with interest to the termination of his second volume, to con- 

 clude" so valuable a contribution to science. It will be found particularly so as affording enlarged 

 means of comparison with the products of Fossil Conchology. — Literary Gazette.
