Greenland and Iceland, and ijerhaps Denmark. (Morch, I. e.) I must 

 treat it as one of the circumpolar species of the Northern Eegion. 



Animal not observed. 



This species is easily distinguished by its bulbous, turreted spire, 

 and by its light horn-color, broken by longitudinal white vittse. When 

 the epidermis is removed the shell is of a dead white. The specimen 

 figured is in Mr. Bland's collection. 



The jaw is said by Morcli to have lateral denticles as in S. amphibia.
