DENTALIUM. 451 



the anterior portion of the body ; it is cylindrical, thick, 

 fleshy, pointed with a conical process, and cleft below ; 

 and in the groove we see the mouth in the shape of a com- 

 pressed process, projecting forwards, and with its edge 

 fringed with short tentacular papillae."* Mr. Clark re- 

 marks that the branchiae of this species are of a paler green, 

 more scanty, thin and delicate. 



It is found all round our coasts, and is especially 

 abundant in the north. On the southern coasts of Eng- 

 land it is rare, and its place is taken by the next species. 

 It lives buried in sand or sandy mud in from ten to one 

 hundred fathoms water ; we have taken it most abun- 

 dantly in from forty to seventy fathoms. On the coasts of 

 the continent it ranges from Norway to Spain.
