PLEISTOCENE FOSSILS. 237 



yet been found fossil, though the three former at least live in the gulf 

 of St. Lawrence.* 



Cardium pinnulatum. Conrad. 



Fossil Leda clay; Lawlor's Lake and St. John, N.B. (Matthew). 



Recent Gulf St. Lawrence, and coast of Nova Scotia and New 

 England. 



Cardium Islandicum. Linn. 



Fossil Riviere-du-Loup ; Murray Bay ; Saguenay ; Little Metis ; 

 Vancouver Island (G. M. D.) ; Portland, Maine ; Lawlor's Lake, N.B. ; 

 Greenland (Moller). 



Recent Riviere-du-Loup ; Little Metis ; from Greenland to New 

 England. 



Our fossil specimens are mostly small, and similar to the northern 

 variety or sub-species named by Stimpson C. Hayseii, and which also 

 occurs living as far south as Nova Scotia, and seems to be the C. ciliatum 

 of Fabricius. Decorticated specimens are not distinguishable from 

 G. Dawsonii of Stimpson, from the Pleistocene of Hudson's Bay ; of 

 which I have seen only specimens in this state. 



Cardium (Serripes) Grcenlandicum. Chemnitz. 



Fossil Leda clay and boulder-clay, Quebec ; Riviere-du-Loup ; 

 Murray Bay; Lawlor's Lake, &c., N.B. (Matthew); New Richmond; 

 Restigouche ; Bathurst (Paisley) ; Cape Elizabeth, Maine ; Labrador 

 (Packard) ; Greenland (Moller) ; Chaudiere Station. 



Recent Little Metis ; Gaspe ; Gulf St. Lawrence, sometimes of 

 large size ; Arctic seas, and Greenland to Cape Cod. 



This shell is somewhat rare and of small size in the Post-pliocene, 

 and has not yet been found higher up the St. Lawrence than Quebec. 

 Specimens of good size occur at Portland. 



Kdlia Suborbicularis. Mont. 

 Black Point, N.B. (Matthew). 



* Astarte quadrans, Gould, has been dredged, living, off Esquimaux 

 point, on the north shore of the St. Lawrence. Astarte crenata, Gray, 

 and a small form of A. crebricostate, Forbes (- A. lens, Stimpson), 

 have been dredged in 200 to 300 fathoms between Anticosti and the 

 south shore. The form of A. undata, Gould, which comes closest to 

 A. sulcata, is abundant, living, in Northumberland straits and 

 between Cape Breton and Prince Edward Island. J. F.W. A. castanea 

 occurs in Minas basin, Bay of Fundy.
