Specific Characters. — Shell ovato-fusiforra; whorls 6, somewhat convex, distinctly 

 but obtusely carinate, with a narrow sloping shelf below the suture, the last two- 

 thirds the total length ; ornamented by about sixteen to eighteen inconspicuous 

 longitudinal ribs, hardly reaching the base of the shell, slightly tuberculate on the 

 keel, and by excessively fine spiral ridges, closely crowded together ; suture slight ; 

 mouth ovate, contracted below, ending in a short and open canal. 



Dimensions. — L. 14 mm. B. G mm. 



Distrihufion. — Recent: western and northern coasts of Norway; Finmark, 

 Lofoten Islands, Iceland, White Sea, Nova Zembla, Kara Sea, Siberian coast, 

 Behring Sea, Greenland, east coast of North Amei-ica. 



Fossil : Coralline Ci'ag : Boyton. AValtonian : Little Oakley. 

 Newbournian : Waldringfield. Butleyan : Butley (A. Bell). Wexford, Isle of Man. 



Pleistocene : Bridlington ; King Edward, Banffshire. Norway, Murman coast. 



Bemarks. — This form is considered by most conchologists to be a distinct 

 species, agreeing with the Recent North American shell B. harpnlaria. It approaches 

 B. turricida more nearly than some of the Belas before described, and Mr. Friele, 

 while admitting it to be in all essentials coincident with the American form, remarks 

 it may possibly be a local variety of the latter. They are easily distinguished, 

 however, and as in view of the fact mentioned above that B. turrinda belongs to 

 the upper zones of the Crag, and is a characteristic British form, while the other, 

 unknown in British seas, is characteristically northern, I agree with those 

 who consider they should be kept specifically separate. Mr. Friele states that 

 B. harpularia was dredged by the Norwegian Expedition at Bodo, Tromso and 

 Hammerfest in 10 — 30 fathoms, but that it is distributed also along the west and 

 north coasts of Norway, beginning at Christiansund, as well as in the regions 

 given above. 



I have received two Recent specimens from Stockholm, one of which has a 

 larger number of longitudinal costse than the other. Tlie fossil from Boyton, here
