CONCHOLOGIA SYSTEMATICA, 



OR COMPLETE SYSTEM OF CONCHOLOGY : 



IN WHICH THE LEPADES AND MOLLUSCA ARE DESCRIBED AND CLASSIFIED ACCORDING TO 



THEIR NATURAL ORGANIZATION AND HABITS ; 



BY LOVELL REEVE, A.L.S., F.Z.S , Etc. 



WITH 300 HIGHLY-FINISHED COPPER-PLATE ENGRAVINGS, 

 BY MESSRS. SOWERBY ; 



CONTAINING ABOVE 1500 FIGURES OF SHELLS. 



A Tabula Methodica, showing the distribution of the genera at one view, is given at the commencement ; and every genus is 

 then faithfully 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 distinguishing characters, the various situations to which it has been assigned in the system by different 

 authors, and the peculiarities of habit and organization of the animals referred to it, are at the same time fairly discussed. Amongst 

 the genera adopted, are included nearly the whole of those advocated by Lamarck ; the author has at the same time carefully 

 abstained from introducing any new ones of his own, and only such of those proposed by modem authors are admitted as have 

 resulted from positive discovery. It has, however, been considered useful to notice the superfluous genera of modern speculators 

 in the places to which they refer, and to include them in an index of nomenclature at the end of each volume. 



The Work is divided into two volumes ; the first contains the Lepades and Bivalve Mollusks, illustrated by 130 plates of shells, 

 and the second contains the Univalve Mollusks, illustrated by 170 plates, including 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.

AUTHOR OF THE ' CONCHOLOGIA SYSTEMATICA.' 

 ILLUSTRATED WITH ORIGINAL FIGURES DRAWN AND LITHOGRAPHED EXPRESSLY FROM NATURE 



By G. B. SOWERBY, Jun. 



The Conchologia Iconica was introduced at the commencement of the year 1843 for the purpose of illustrating all the 

 known species of Shells by good natural-sized figures, and new and elaborate descriptions ; neither pains nor expense have been 

 spared to gain information and obtain specimens from every possible source, and this unabated desire to perfect the Work, coupled 

 with the regularity of its monthly issue, has established a circulation which is most encouraging to the Author-proprietor. 



The following genera being now completed, monographs of any of them may be had separately in neat stiff covers : — 



The genera Pleurotoma and Mitra are now publishing.
