70 THE ECONOMIC MOLLUSCA OF ACADIA. 



Habits. This is the Scallop which is of so much importance in the 

 United Stales markets. As it is so rare in Acadia, indeed hardly coming 

 within the limits of this paper at all, it is not thought best to describe it 

 in detail. When found, it may be distinguished from our two Scallops 

 described above, by the coarse radiating ribs, about twenty in number, 

 and the nearly equal "ears" or lateral projections from the shell, 

 forming the hinge. Its habits resemble those of P. teymicostatus, described 

 above. It is possible that it may be found in the Gulf of St. Lawrence 

 along with the southern shells there, and if not, it is extremely probable 

 that it would flourish there if introduced. Indeed, as mentioned under 

 the last species, a Scallop having a "large ribbed shell and serrated 

 edge," has been described as living on the shores of Prince Edward 

 Island. It may be not improbably this species. 



Economics. Its use to man may be best described in 

 connection with our native Scallop, as both are available for 

 the same purposes.

Distribution, {a) General; — Littoral zone to more than, 

 one hundred fathoms. North Carolina to Arctic Ocean and 

 circumpolar. On European coast, southward to Mediterranean 

 and Black Sea; on Asiatic coast to China and Japan; on 

 Western American coast to California.

 where on the southern coast from Grand Manan to St. John, 

 and probably much further. Bay Chaleur, Bell. Shediac,. 

 Whiteaves. (In N. S.) Annapolis Basin and Digby Gut, 

 common, Verkruzen. Whole coast, Jones. Prince Edward 

 Island, Daiuson. Very abundant everywhere on the coast of 

 Acadia. 



Habits. Without doubt, this is the most common and abundant 

 Mollusc on the coast of Acadia. There is probably not a mile of shore 

 on our whole coast line which is without it, and everj'body who visit*
