Purpura lapillus, Lamarck (1822) ; at auct. 



This species is said to be common at low-water in the Bay of Fundy and 

 Atlantic coast of Nova Scotia, but its exact range in the River and Gulf of 

 St. Lawrence has yet to be ascertained. In the latter region it has long 

 been known to occur on the Gaspe coast, from Gaspe Bay to Metis, and all 

 round the Island of Anticosti, but there are no records of its having been 

 taken on the north shore. Although recorded as a Greenland shell by 

 Fabricius and Moiler, Packard failed to find it on the north shore of the 

 Gulf, near the Strait of Belle Isle, or on the Labrador coast. Its name is 

 not included in Miss Bush's list of the Mollusca dredged on the Labrador 

 coast by the Stearns expedition, and there are no specimens of it in the 

 collections made of late years in Hudson Bay and Strait. 



In a fossil state P. lapiilus is common in the English Pliocene. It is 

 found also in the Pleistocene of Scandinavia and Maine, but its name does 

 not occur in Sir J. W. Dawson's latest list of Canadian Pleistocene fossils.
