to be a rare form in the living state ; as a fossil it has only been recorded, as far 

 as I know, from Selsey. 



It was dredged in 92 fathoms during the Porcupine Expedition on Adventure 

 Bank at station 30.

Specific Characters. — Shell small, fairly solid, fusiform, turreted ; whorls 6, 

 subscalariform, obtusely carinate beloAV the suture, the last much the largest, 

 about five-eighths the total length ; suture deep, slightly oblique ; spire 

 attenuated ; mouth ovato-oblong, nearly half the length of the shell, somewhat 

 expanded, contracted below, angulate above ; strongly sculptured with broad, 

 thick, closely-set longitudinal ribs, not far apart, and by spiral striae which 

 produce rather coarse granulation when they intersect the latter ; canal short, 

 distinct. 



Dimensions. — L. 8 — 10 mm. B. 5 — 6 mm. 



Distribution. — Recent: Norwegian coast, Tromso, Greenland, Labrador, New- 

 foundland. 



Fossil: Ledn iny<ilis-bed, East Runton. 



Remark*. — The fossil specimen from the Norwich Museum found in the Leda 

 myalis-bed at E. Runton and figured under the present name, has been identified 

 by Dr. Odhner, who has kindly sent me a recent shell from Finmark for com- 

 parison. It is a distinct form, easily separated from the other Crag Belas by its 

 coarse, closely-set and nodulous costse. The whorls are obtusely angulated above, 

 forming a clearly-marked keel with a sloping ledge below the suture. 



Among other imperfect specimens of Bela from the Leda mi/alis-bed at E. 

 Runton received from my friend Mr. Kennard, I noticed some which seemed to 

 belong to the following species, viz. B. harpularia, B. mitrula, and B. 

 Trevelyana.
