PREFACE. 



This List has been compiled to meet a 

 want often felt and expressed amongst amateur 

 naturalists. The nomenclature and classifica- 

 tion, followed is that adopted by the late 

 DR. GWYN JEFFBEYS in his "British Concho- 

 logy." Zoological Records, Proceedings of 

 various learned Societies, and Reports of 

 Marine Dredging Expeditions, have enabled 

 the compiler to include such genera, species, 

 and varieties as are now known to occur in 

 British seas, thus making the List fairly 

 complete up to the date of publication. 



It is hoped the size adopted will be found 

 convenient for inserting in a Pocket Case; 

 and that this fact will enhance the value of the 

 List to practical workers in the delightful study 

 of British Conchology. 



Some delay has been unavoidable in 

 placing this compilation at the service of 

 naturalists; but if it shall prove useful, the 

 compiler will feel amply.rewarded.
