It is chiefly in shape that the variation, permitted to 

 each species, displays itself in the present shell. The 

 ordinary form of medium-sized specimens is oval-fusiform, 

 with the spire occupying about two-fifths of the dorsal 

 length (and a still more slender variety is likewise oc- 

 casionally taken) but the greatest diversity of figure is 

 that presented by the large swollen Irish (deep water?) 

 example, dehneated in our engraving, wherein the body 

 is not merely more tumid than usual, and twice as long 

 as the spire, but the area of it is vastly more extended 

 than in general, and the outer lip is extraordinarily pro- 

 minent and patulous.
