Plowing along throughthe wet sand by means of itsenormous foot, it no soonerreaches an unfortunateclam, than the flint drillwhich it carries in its mouthFig- 25- is stretched out and begins to accomplish its work of destruction. The helplessclam has no means of flight from such an enemy; andif its hard shell is not a sufficient protection, it is ina sad case indeed. And in truth, the case is sad, forthe shell is no match for the drill, and when once ithas reached the savory meat inside, the robber makes. 46 THE NATICAS. short work of his victim. A high-handed proceed-ing, no doubt; but then, it contrasts rather favorablywith our way of opening clams and oysters. The size of this shell varies greatly with its ageand conditions. Specimens have been found as largeas six-inch globes, but such giants are not are ordinarily the size of average apples. Thecolor is yellowish white and the form spheroidal; thesurface is nearly smooth, the operculum horny, andthe umbilicus large. This figure was drawn from aspecimen collected at Olympia, Washington Terri-tory. A somewhat similiar species, which also lives innorthern waters, may be distinguished by its closedumbilicus and shelly operculum. Its name is Naticaclan set, Brod. and Sby., Nat-i-ca clau-sa. Neverita Recluziana, Petit, Ne-ver-i-ta Re-cluz-i-an-a, shown in Fig. 26, is a southern species
