CONCHOLOGIA ICONICA ; or, Figures and Descriptions 
of the Shells of IMoUusks, with remarks on their Affinities, Synonymy, and 
Geographical Distribution. By Lovell Reeve, F.L.S. Demy 4to, pub- 
lished moathly 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 o])tion in portions, each of which is complete in itself. Each 
genus, as the work progresses, is issued separately, with Title and Index ; and an 
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 arc 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.
