y. Trait^ ElSmhitaire d« Conchy liologie, avec I'appHcation de cette Science & 

 la Geognosie. Par G. P. Deshayes, Llvraisons, 1 — 5. 8vo. Crochard. 



In a former number (vol. xxvi. p. 212), we noticed with 

 great commendation the first part of this work, and we at the 

 same time gave a sketch of the plan which the author intended 

 to follow. The four succeeding parts fully justify the high 

 expectations we had formed from the specimen then before us, 

 and from the distinguished reputation of M. Deshayes. The 

 1st number contains a chapter of general considerations on 

 Conchology and the commencement of the 2d chapter, which 

 xjmbraces an admirable digest of the histox'y of Recent and 

 Fossil Conchology, and is concluded in the 4th number. The 

 5th and 6th numbers contain portions of the third chapter of 

 the introductory matter, being a masterly essay on the com- 

 parative anatomy of the Mollusca ; and likewise the beginning 

 of the systematic treatise on the families and genera. The 

 information communicated in the descriptions and general ob- 

 servations is clear, full, and quite up to the present state of 

 science. The following genera have already been treated of: 

 Aspergillum, Clavagella, Gastrochaena, Septaria, Teredo, and 

 Teredina. Forty plates have appeared in the five numbers, 

 and their careful execution and beautiful colouring are worthy 

 of the Text.
