The young Shells of this species vary considerably in their colours 

 and markings, but are in general remarkable for their elegance ; as 

 they encrease in growth, those colours and markings gradually fade, 

 and in old Shells become altogether obscure. It is found in plenty on 

 most of the southern coasts of England and Wales. 



* Gmelin makes a new species of Lister's shell in the Systema Naturae, under the 

 name obscura, without noticing any other author who describes the same kind " Venus, 

 ebscura testa fusca: striis perpendicwlaribus tenuissimis, p. 32S9. sp. 99."
