 2. 16*. 



Intended as a guide to the collector of shells in arranging and naming his 

 specimens, while at the same time inducing him to study them with reference 

 to their once living existence, geographical distribution, and habits. Forty- 

 six of the plates are devoted to the illustration of the genera of shells, and 

 sixteen to shells with the living animal, all beautifully coloured by hand.

A complete history of the British Land and Freshwater Shells, and of the 

 Animals which form them, illustrated by Wood-Engravings of all the Species. 

 Other features of the work are an Analytical Key, showing at a glance the na- 

 tural groups of families and genera, copious Tables and a Map'illustrative of 

 geographical distribution and habits, and a chapter on the Distribution and 

 Origin of Species. 



CONCHOLOGIA ICONICA; or, Figures and Descriptions 



of the Shells of Mollusks, with remarks on their Affinities, Synonymy, and 

 Geographical Distribution. By LOVELL REEVE, F.L.S. Demy 4to, pub- 

 lished monthly in Parts, 8 Plates, carefully coloured by hand, 10*. 



Of this work, comprising illustrations of Shells of the natural size, nearly 

 2000 Plates are published, but the plan of publication admits of the collector 

 purchasing it at his option in portions, each of which is complete in itself. Each 

 genus, as the work progresses, is issued separately, with Title and Index ; and au 

 Alphabetical List of the published genera, with the prices annexed, may be pro- 

 cured of the publishers on application. The system of nomenclature adopted 

 is that of Lamarck, modified to meet the exigencies of later discoveries. With the 

 name of each species is given a summary of its leading specific characters in 

 Latin and English ; then the authority for the name is quoted, accompanied 

 by a reference to its original description ; and next in order are its Synonyms. 

 The habitat of the species is next given, accompanied, where possible, by par- 

 ticulars of soil, depth, or vegetation. Finally, a few general remarks are offered, 

 calling attention to the most obvious distinguishing peculiarities of the species, 

 with criticisms, where necessary, on the views of other writers. At the com- 

 mencement of the genus some notice is taken of the animal, and the habitats 

 of the species are worked up into a general summary of the geographical distri- 

 bution of the genus.
