The plates appear to be the same re-drawn with the vernacular 

 names and references inscribed thereon. 



WODARCH AND MaWE. 



As an episode in the study of conchology the works of these two 

 writers may be cited. 



In 1820 appeared : " An | Introduction | to | The Study of 

 Conchology, | describing | The Orders, Genera, and Species | of | 

 Shells ; | their most prominent characteristics, and usual | mode 

 of classification. | With | observations on the nature and proper- 

 ties I of the animals ; | and | directions for collecting, preserving, 

 and I cleaning shells. | By | Charles Wodarch. | London : | Pub- 

 lished by Longman, Hurst, Rees, Orme, and Browne, | Paternoster 

 Row ; I and by J. Mawe, No. M9, Strand. | 1820." 



My copy is in the original boards, and on the back of the cover 

 is labelled : " Introduction to Conchology. Coloured Plates, 

 Price 12.S." 



It is a small octavo, the preface, contents, introduction, and 

 classification occupying twenty-four pages, the text proper 120 pages, 

 and there are four coloured plates showing sixty-three figures. 



There is a couple of pages of advertisement sewn in at the front 

 from which I note : " Just published. By J. Mawe 149, Strand. 

 A Treatise on Shells, with plates, price 7s., written strictly after the 

 system of Linnaeus, describing the characters of the orders, genera, 

 and species ; with an extensive catalogue of names under each 

 genus : to which is added, the best mode of cleaning and preserving 

 shells." This work seems at present unavailable. 



Then appeared " Wodarch's Introduction . . . Second Edition, 

 Revised and considerably Enlarged by J. Mawe . . . 1822 ", with an 

 " Advertisement to the Second Edition. The alterations in this 

 edition, consist in the introduction of some species which were 

 unknown at the tim.e of Linnseus ; the division of the genera into 

 classes, whereby the different characters of the genus may be more 

 readily recognised :' the addition of the English names to many of 

 the species ; a comprehensive nomenclature of the terms used in 

 Conchology ; and lastly, by the embellishment of three new plates ; 

 the Frontispiece showing four genera of spiral shells, and the two 

 others exhibiting the hinges of Bivalves, and displaying the 

 peculiarities of some particular shells. J. Mawe. 149 Strand. 

 Feb. 1822." 



The contents and glossary of terms used in conchology take up 

 fifteen pages ; the introduction, classification, and text proper 

 extending to 152 pages. My copy in original boards is lettered on 

 the back : " Elementary Treatise on Conchology with Plates, 

 colored." 



The frontispiece has seven coloured figures : Buccinum dimidiatum, 

 B. subulatwn, Stromhus fusiis, Murex coins nicoharicus, M. coins,
