THE following pages are designed to comprize 

 the Linnean Classification of Shells, with a general 

 reference to such particulars in the habits and 

 instincts of testaceous animals, as tend to render the 

 science of Conchology equally interesting with thai 

 of Botany. 



The Author is indebted for the scientific arrange- 

 ment to the works of Mawe and Brooke ; for the 

 anecdotes connected with the different species, to 

 the " Conchologist's Companion ;" and neither 

 time nor labour has been spared, to render the 

 Catechism as complete as its limits would permit.
