Shell an inch and a half in diameter, covered with a 

 creased or coarsely wrinkled skin, somewhat glo- 

 bular, with the mouth a little longer than wide, 

 the edge of which is slightly reflected ; of a dull 

 olive colour with generally four interrupted brown 

 bands, one and rarely two of them penetrating the 

 mouth. It varies much in colours and markings, 

 but is readily known by its wrinkled coat. 



The internal spicula or darts, which this species ejects 

 in the spring of the year, are about a quarter of an 

 inch long, slender and tapering to a fine point,
