These notes contain a list of about fifty shells, which, with 
very few exceptions, are specifically identical with recent ones, 
living on the coasts of Northern America from Massachusetts 
to Greenland. 
Notices concerning the recent species of Buccinum found in 
the pleistocene beds of Canada and Maine by the same author

Tw^enty-three shells have been found, ^'at an elevation of
