It fi-nm the Gulf of Mexico to Lab- r a d o r , and is found oti sandy l)eaclies from low water to a depth of ab out sixty feet. The shell is covered with a horn}', light- brown skin, and is not deeply fur- rowed by lines of growth. It grows to be fully six inches long and four wide The ^'-^'^ ''â¢â â ''UEI' clam. From IHe. Young and old. Annisqnam, Mass. Siphon IS short and thick, while the foot is large, stout and muscular, and enables tlie clam to dig rapidly into the sand.

The Soft-Shell 01am, {Mya arcnarki. Fig. 82). This is often called the "long clani ' or "; It is found in sandy or muddy shores from the Carolinas to the Arctic, and also on the Northern coasts of Europe. It is common in the sheltered banks of l)ays and estuaries between tide limits, where it burrows in the ground by means of its muscular foot, having its long, extensible siphon pointing upward. When the tide is high the siphon is extended so as to reach to the opening of the burrow, but it retracts.
