It has fomewhat the habit of the precedmg fpecies, but 

 is readily diftinguiflied by being thick and opaque; in 

 being longer in proportion to its breadth, and in having the 

 volutions more raifed ; the body whirl too is not fo large 

 , in proportion to the fuperior ones. In fome inftances 



we have feen this (liell, wlien young, with an inclination 

 to a groove, and umbilicus on the pillar lip, but never 

 fo large as in the other, and which always clofes up with 

 age. 



We are indebted to Mr. Bovs for our firfl; acquaint- 

 ance with this fpecies, from whom we received a great 

 many fpecimens of all fizes, with a reference to Mr. 

 Walker's figure as above quoted: and who informed 

 us, it is not uncommon on the coaft of Sandwich. 



Have fince found it in tolerable abundance on the 

 fhore of Biddcford bay. 



It feems Mr. Walker had by fome accident made a 

 millake, in placing a minute figure by the fide of the 

 large one.
