Unidentified Clam From Liverpool N.S, Canada

[bekkievandenberg]

I found a ton of clam shells at Summerville Beach in Liverpool Nova Scotia .
Can someone please help me to identify them ,
I don't think they are "Soft Shelled Clams" because .. they don't have a brittle shell .
This one in the picture is about an inch and a half long .
Thanks !
(Sorry, it's a huge picture)
