PLATE CLXVI. 



Chiefly distinguished from Lepas Anatifera, described at the com- 

 mencement of this work, by having the valves striated with elevated 

 lines ; the valves in the former being perfectly smooth. Lepas ana- 

 tifera has been heretofore considered as a native of the American and 

 Atlantic seas ; but that it has been likewise found upon the English 

 coast, there is no reason to dispute, the shell with the living animal 

 has been dredged up at Weymouth, as well as the preceding species. 

 We have the valves of this shell likewise in the collection of Da 

 Costa, as an English species.
