THE ECONOMIC MOLLUSCA OF ACADIA. 
97 
Distribution. (a) General ; — Low-water mark to ten 
fathoms or more. Cape Cod to Labrador. 
(ft) In Acadia; — (in N. B.) Grand Manan, common in 
sand at low water, buried at a depth of four inches, Stimpson , 
Verrill. (In N. S.) Annapolis Basin, St. Mary’s Bay, rare, 
Verlcruzen. Chester, Lunenburg, Mahone Bay, River John, 
Willis. Not reported from Prince Edward Island. Having 
been reported from so few places, it is impossible to state its 
distribution on our coasts. 
Habits. Similar to the last species, M. solidissima, in habits, and 
very like it in appearance. It is smaller, rarely exceeding four inches 
in length, but it is never distinguished from it by fishermen. The chief 
mark by which M. solidissima may be separated from it, is the presence 
of striations on the long hinge teeth, M. ovalis having none of these. It 
is much less common than M. solidissima , and is a more northern shell. 
Economics. Probably it can be used for the same purposes 
as M. solidissima , though its smaller size and greater scarcity 
must render it less valuable. Mr. Willis says, referring to 
this species, that it “sometimes finds its way to Halifax 
market, and is readily disposed of.’’ 
23. Mya arenaria Linnaeus. 
Clam, Soft Clam, Long Clam, Sand Clam. 
Mic-mac , Aas-uk. Passamaquoddy , Ess-sook (or

Distribution, (a) General ; — Between tide-marks to 
more than one hundred fathoms. South Carolina to the 
Arctic Ocean, Northern Europe and south to England and 
France. Northeastern coast of Asia to China and Japan. 
Sitka, Alaska. 
(b) In Acadia; — (in N. B.) Abundant everywhere in sand 
and mud on the southern coast from Grand Manan to St. 
John and probably much further. Bay Chaleur, Bell. Shediac, 
Wliiteaves. (In N. S.) Annapolis Basin and Bay of Fundv, 
common, Verlcruzen. Halifax Harbour, etc., very common.
