484 Revision of British Mollusca. 



The radula lias seven teeth in each transverse row ; all the 

 teeth are simple and of nearly equal size, except the outer 

 laterals, which are longer. 



The eggs are ovoid, with a mamillary distal extremity, and 

 narrowed at their base into a stalk, with which the seaweed 

 to which they are attached is grasped. 



Besides the hectocotylization of the arm in the male, the 

 cuttle-bone is smaller and less hollowed than in the other sex.
