 Mr. W. D. Sutton in the Quarterly Journal of Conchology, i. 1874.

 Conchological Society, the following list has been compiled. 



For the sake of uniformity in the several County Histories the same 

 nomenclature is here followed as in precursors in the series, but for the 

 most recent information on this subject reference should be made to the 

 List published by the Conchological Society.
