cunate, in the latter case slightly constricted in

Tilis characteristic Surirella is recorded by 

 A. Schmidt from three localities: Holstein: Pensacola; 

 Scotland: Lodgie Coldstone. As de Toni (Syll. p. 595) 

 nientions it as occurring »ad« Holstein tliese three 

 localities are doubtless salt or brackish-water loca- 

 lities. From the Færoes it appears scattered about in 

 manj' of the gathcrings and it suits the form figured 

 in A. S. Atl. ligs. 21 and 22 on tab. LVI so perfectly that I do not hesi- 

 tate in placing it under this species.
