Shell hardly a quarter of an inch long, and about one-fifih as 

 broad, white, pellucid, and glabrous, and remarkable for the 

 uncommon obliquity of the sutures. Linnagus has erroneous- 

 ly cited Gualter's excellent figure of this shell for Helix oc- 

 tona, which led Muller to quote that species for his B. Aci- 

 cula, though he remarked that it did not accord with the Lin- 

 na^an character. Schroeter has committed the same error, 

 and has been followed by Gmelin, who has very carelessly 

 arranged the true Helix octona as a variety of the same spe- 

 cies. B. Acicula of Gmelin is a different shell, and the 

 species has been constituted entirely from Lister, t. 1055. f. 

 7, which is probably a variety of Strombus ater.
