Dredged iu great abaiidriiice in 8 to 13 fathoms, among CladopJiora, on 

 the south side of Saint Ignace ; in 4 to G fathoms in the cove at the east- 

 ern end of the same island ; in G to 8 fathoms among the Shite Ishinds;

An Amnicola, found in great abundance iu the stomach of white-fish 

 taken at Sault Sainte Marie, is doubtfully identified with this species by
