liion perrhoinkle, T. littoreus, and T. rudis, differ To 

 much at various periods of growth, that it is no eafy 

 matter to identify them ; this feems to be the molt dif-

 be found on fome parts of our coafls, that would con- 

 ned this with T. littoreus, as the varieties of that fhell 

 in its infant flate are infinite.
