MULTIVALVES. LEPAS. 23 



The Indian, American, Atlantic, and Arctic oceans, 

 alike provide a habitat for the species of this genus; 

 and no less than eleven of them are to be occasionally mot 

 with on the British coasts. 



The Lepas, in all probability, derives its name from its 

 custom of adhering to crags of rocks, and other projections 

 in the sea.
