north-west coast as Monterey, California. It is " abundant about Bering 

 Sea." "The original Tellina Balthica wsls the thin form from the Baltic, 

 not the solid Tellina solidula, Pulteney, which is better known to collectors.'' 

 "The former is identical with our common American type " (Dall).* 



With Saxicava rugosa this species occurs in enormous numbers in the 

 Saxicava sand at many localities in the St. Lawrence and Ottawa valleys, 

 etc., and it has been found also in the Leda clay. In the St. Lawrence 

 valley it has recently been collected by Mr, R. Chalmers as far to the west- 

 ward as Brockville, Ont.

From Long Island Sound northward to Nova Scotia, the Gulf and mouth 

 of the River St. Lawrence, Labrador, Hudson Bay and Strait, to Gi'eenland 

 and the Arctic Ocean, in from 3 to 80 fathoms. It is found on both sides of 

 the Atlantic and has been taken on the coast of British Columbia. Dall 

 (op. cit.) says that it occurs in the " Ai'ctic Ocean generally, and on the Pacific 

 south to the Okhotsk and Japan seas on the west, and to the Aleutians and 

 Oregon on the east." Dr. Bell dredged several specimens of it at Ashe Inlet 

 and Port Burwell, Hudson Strait, in 15 fathoms, in 1884. Still more recently, 

 Mr. Low has dredged similar specimens on the south side of Hudson 

 Strait, between King George Sound and the bottom of Ungava Bay, in the 

 summer of 1897, while accompanying the Diana exploring expedition; on 

 the east coast of Hudson Bay, near the mouth of the Povungnituk River, in 

 10 to 15 fathoms, in 1898; and in Richmond Gulf, on the east coast of 

 Hudson Bay, in 15 to 25 fathoms, in 1899. 



In a fossil state Sir J. W. Dawson says that this species is extremely abun- 

 dant in the Leda and boulder clays of eastern North America, and that it has 

 been found in the Pleistocene deposits of Maine ; at Duck Cove, St. John, 

 N.B.; at New Richmond, Anticosti, Riviere des Outardes, Riviere du Loup, 

 Murray Bay, Quebec, Chaudiere Station, and Montreal, P.Q.; also at 

 Labrador, Greenland, and northern Europe. It has also been found fossil on 

 the east coast of Hudson Bay, two or three miles up Little Whale River, 

 by Dr. Bell, in 1877 ; at James' Bay, near Moose Factory, by A. S. 

 Cochrane, in 1877 ; and at the Limestone Rapid of the Fawn Branch of 

 the Severn River, Keewatin, by A. P. Low in 1886.
