192 BIOLOGICAL SURVEY OF 



M. CALCAREA (Gmeliii). {Tellina calcarea Gmelin, 1790, 

 Syst. Nat. ; M. proxima Gould, 1870, Inv. Mass., p. 95, fig. 401 ; 

 M. sabulosa Verrill, 1873, Inv. Vineyard Sound ; M. calcarea 

 Dall, 1900, Proc. U. S. Nat. Mus.) Also a common form in 

 the inner bay, but we did not take it outside. Stations : D 10, 

 11, 14, 21-24, 33, 34. No definite Woods Hole records, though 

 according to Verrill it is taken on muddy shores between tides 

 in that region. Eeported from Eastport, Casco Bay, and 

 various places to off Stonington. Extends to Greenland, both 

 sides of Atlantic, and has been taken on coast of British 

 Columbia.

 1873, Rep. Inv. Vineyard Sound; E. directus Dall, 1899, U. S. 

 Nat. Mus.) The 'razor shell' that is commonly found on the 

 beaches of the New England coast. Some quite large patches 

 along the shores of the Bay. Is beginning to be used in chow- 

 der as a substitute for M. arenaria. One specimen an inch 

 long was dredged at station 125. Reported from various 

 Atlantic coast places to Gaspe, low-water mark to 40 fathoms.

 S. (Hemimactra) solidissima (Dillwyn). (Mactra solidis-

 1870, Inv. Mass., p. 73, fig. 387; S. {Hemimactra) solidissima 

 Dall, 1894, Nautilus.) This is the beach or hen clam. Re- 

 ported from the coves on the west side of the Island. Speci- 

 mens said to have weighed 2 pounds reported from Newberry 

 Neck. This is the shell that the Indians used as a tool to hoe 

 corn. We took one specimen at D 2, at a depth of 60 feet. 

 Common from Maine to Connecticut, Atlantic coast north-
