Hah. —Sea-coast of Washington Territory; Dr. Cooper. 
This shell inhabits the sand immediately upon the sea-beach, burrowing about the edge of 
the usual low tide, where it can be dug up with little trouble, as it is only a few inches from 
the surface. It is considered, and justly, the best of the many fine eatable mollusca of the 
coast, excepting always the oyster. Severe storms wash up many of these shells, but they 
soon crack under the sun’s rays, and the beautiful epidermis falls off. 
This is the only truly marine mollusc I have been able to find ont the sandy sea-beach near 
the Columbia river. It extends northward as far as the beach is sandy, but is not found, I 
believe, anywhere within the Straits of De Fuca.—C.
