Fossil in the Pleistocene of Northern Europe, the northeastern coast of 

 America, and Alaska ; living in all arctic and boreal seas, and, on the east coast 

 of America, south to Georgia ; in Europe to the Mediterranean. 



The original Tellina balthica was the thin form of the brackish waters of 

 the Baltic, and not the solid, heavy, smooth shell known as Macoma solidula 

 Pulteney, which is the variety of balthica best known among collectors. It is 

 probably because comparisons of the American shells have usually been made 

 with British specimens of balthica var. solidula that American authors have been 

 disposed to separate the two and give the American shell a different name.
