MARINE MOLLUSCA OF LYME REGIS. 



By J. W. CUNDALL. 



(Read before the Conchological Society). 



The ancient little town of Lyme Regis is situated at the 

 western extremity of Dorsetshire, and is immediately contiguous 

 to Devon. It is a picturesque primitive place, and may be 

 made the scene of a pleasant, if quiet, holiday. The beach is 

 sandy, but the most careful search fails to reward the con- 

 chologist with any extensive or very special results. At low 

 water numerous low-lying, weed-covered rocks are revealed, but 

 these are singularly destitute of littoral molluscan life. They 

 are to a great extent composed of the soft blue lias of the 

 neighbourhood, and are burrowed in all directions by 'rock- 

 borers,' fine and typical examples of which abound, belonging 

 to the three following species : — 



Pholas dactylus Saxicava rugosa 



Pholas Candida 

 Upon the rocks a few common species may be obtained, these 

 consist of 



Chiton fascicularis Patella vulgata 



Littorina littorea Patella athletica 



Littorina littoralis Trochus umbilicatus 



Littorina rudis 



The place is, however, a great resort of lobster smacks, 

 and the empty pots, in considerable numbers, are frequently 

 deposited on the ' Cobb.' These generally well repay examina- 

 tion, and from them the following additional species were 

 procured : — 



Nassa reticulata Turritella connmunis 



Nassa incrassata Murex erinaceus 



Trochus cinerareus Cypraea Europa 



Trochus ziziphinus Puncturella Noachina 



Phasianella pullus
