MARINE SHELLS IN STRATIFIED CLAYS. 75 



John, consist of gray and reddish days, holding fossils which indicate 

 moderately deep water, and are, as to species, identical with those 

 occurring in similar deposits in Canada and in Maine. They would 

 indicate a somewhat lower temperature than that of the waters of the 

 Bay of Fundy at present, or about that of the northern part of the 

 Gulf of St Lawrence. They coi-respond to the Leda clay of Canada 

 and Maine. 



IVIr C. F. Hartt has given, in Prof. Bailey's Report on New Bnms- 

 wick, the following list of fossils from these beds. I have affixed an 

 asterisk to the species found also in the Leda clay and Saxicava 

 sand of Canada.
