XXXI. — Shells of the Littoral Zone ^ and Freshwater and Land 

 Shells J in Jersey. By E. DuPREY. 



It is a well-known fact that the number and variety of shells 

 inhabiting the littoral zone depend much on the extent and 

 nature of the portion left dry by the receding tide. On the 

 coast of Jersey, where the fall of the lowest spring-tides is 

 rather more than 40 feet, and the recess where greatest (at 

 La Rocque) about two miles, species of shells are found at 

 low water which in other places inhabit a depth of several 

 fathoms. This circumstance is particularly favom-able for 

 collectors, the more so as all sorts of ground, rocky, stony, 

 gravelly, sandy, and covered with seaweeds, are to be met 

 with on some part or other of the coast. 



The following list of Jersey marine shells comprises those 

 only which are found between tide-marks and are accessible 

 to every searcher who can occasionally avail himself of a few 

 hours for a pleasant low-water excm-sion. Except when other- 

 wise stated, the specimens have been found living. 



The nomenclature is that of Jeffreys's 'British Conchology.'
