 Ostrea virginica. Gmelin. 



Ostrea canadensis, Lamarck. 

 Ostrea borealis, Stimpson, 1851. 

 (The common oyster.) 



This shell-fish was common in the tidal rivers and bays of the 

 Maine coast, as the Indian shell heaps, notably the one on the 

 banks of the Damariscotta river, in the town of Damariscotta, 

 and dead shells still to be found in the beds of the rivers elo- 

 quently attest. The cause of their dying out on the coast of 

 Maine has not, to our knowledge, been satisfactorily explained. 

 Several attempts, at dift'erent times, to restock the rivers have 

 ended in failure, with the possible exception of a bed in Sheeps- 

 cot river, Lincoln county. There are specimens from this 

 river in the museum of the Portland Society of Natural History 

 that were taken alive by Mr. G. M. Brown, the date of collection 

 not being given. Rev. Henry W. Winkley informs me that he 

 has in his collection a specimen of ostrea virginica from the 

 Sheepscot river at a place called Sheepscot bridge, about two 

 miles above Wiscasset. He further says: "There is a small 

 bed of living oysters there and I understand they have survived 

 from ancient times."
