 Cardium (Cerastoderma J pinnulatum, Dall (1900). 



Grand Manan, "in four fathoms, coarse sand " (Stimpson) ; Bay of Fundy, 

 2 to 80 fathoms (Verrill) ; abundant in L'Etang Harbour, Charlotte Co., 

 N.B. (Ganong) ; Annapolis Basin, not abundant (Verkruzen). Fishing

 in 45 and 60 fathoms (Smith and Harger). Northumberland Strait 

 (Whiteaves) ; Gasp^ Bay (Sir J. VV. Dawson, and the writer), Packard 

 records C. pinnulatum as very common at Salmon Bay, Caribou Island, 

 and says that it did not occur north of the Strait of Belle Isle, But Miss 

 Bush says that a specimen sent by Packard to the Peabody Museum of Yale 

 College, and labelled C. pinnulatum, is a young specimen of C. ciliatuni. 

 The true C. pinnulatum is known to range as far to the southward as Long 

 Island Sound. 



Dr. G. F. Matthew has found this shell fossil in the Leda clay at Lawlors 

 Lake and St. John, N.B.

Common at moderate depths (10 to 50 or 60 fathoms) in the Gulf of St. 

 Lawrence and northward to Hudson Strait and Greenland, often associated 

 with Cardium ciliatum {Islandicum). The species is also known to occur on 

 the Newfoundland Banks (Verkruzen) and on the Atlantic coast of 

 Nova Scotia, southward to Cape Cod, but it has not yet been recorded as 

 having been taken in the Bay of Fundy. 



As an American fossil S. Grcenlandicus has been found in the pleistocene 

 deposits of Maine, New Brunswick, the Province of Quebec, Labrador and 

 Greenland.
