7. Popular Conchology, or the Shell Cabinet arranged ; being an Intro- 

 duction to the Modern System of Conchology. By Agnes Catlow. 12mo, 

 pp. 300, with numerous woodcuts. Longman, London, 1843. 



This little volume will prove a valuable aid, not only to the youthful con- 

 chologid, but even to those who have long studied this beautiful branch of 

 Natural History. Since the Linnean classification has been to a certain extent 

 superseded by that of LamarcJc, such a work has been greatly wanted ; and we 

 rejoice to see it noiv so well executed. Most possessors of shells are ambitious 

 to deHve from them further interest than arises out of the mere contemplation 

 of their beautiful forms and colours, and anxiously enquire for some booh, as a 

 guide to their classification. By the aid of Miss Catlow' s Worh, even beginners 

 Tnay arrange their shell cabinets, in strict conformity with the most advanced 

 state of the science, so far as respects the genera ; aud when the genera are 

 correctly discriminated and classed, the main difficulty of the study is overcome. 

 The system of Lamarck has been closely followed, with a few alterations, which 

 subsequent more accurate knoivledge of the habits and physiology of the mollus- 

 cous animals has rendered essential. The introductory chapter, which is written 

 with clearness and elegance, embodies usefid information respecting the inhabi- 

 tants and the mode of formation and growth of shells. The woodcuts are 

 numerous and accurate. The style of the work is perspicuous and simple ; and 

 there is throughout a gracefulness and refinement of thought and expression, 

 that seems singularly appropriate to the description of these beautifid creations 

 of nature.
