ACMiEA. 437 



multiplied considerably on the north coast of the Isle of 

 Man (E. F.), and is not rare in the north-east of Ireland 

 (W. Thompson). In Scotland it is more common, being 

 abundant between tide-marks in many places in the Clyde 

 district, and generally through the outer and inner He- 

 brides (E. F.). Mr. M'Andrew has dredged it in four 

 fathoms at Stornaway, and in twelve fathoms north of 

 Shapinsha in the Orkneys, where Lieut. Thomas has 

 found it also on the shores of Kirkwall Bay. 



It inhabits the coast of Norway, Greenland, and Boreal 

 America. It is found fossil in pleistocene strata in 

 Sweden.
