 Inhabits the stems and branches of the Gorgonise. Linnaus. 



Mediterranean. Pallas. Eastern Ocean. Bruguiere. 

 It appears to be of the same nature and size as L. spongeosns, 

 and to have a cone, with its base fitted to the base of the 

 valves ; three of the valves are larger and oblique, and the 

 other three are upright, but no mention is any where made 

 of their being spinous, like those of the foregoing species ; 

 the aperture is similar in this respect to that of L. spongeo- 

 sus, and only appears to be lateral, as it has been described by 

 most authors, when the two cones are viewed together on 

 their edge, which is not the natural position of the shell. It 

 has been found imbedded in the substance of several of the 

 Gorgoniae, by Ellis, Pallas, Schroeter, Bruguiere, &c

 Inhabits the South Seas, imbedded in the skin of whales. 



Lamarck. 

 Shell about an inch long, and more than three quarters wide, 



and is found so deeply imbedded in the skins of whales, that 



the top alone is observable ; it is open at the bottom, but 



the top is closed by an operculum of four smooth valves ; 



colour tawny, and the inside white. Mr. Wood says, that the 



sides are divided into six compartments or valves, and that it 



is a true Lepas.
