BELA ODHNERI. 293 



Specific Characters. — Shell small, short, sub-fusiform, whorls 5 — -G, hut slightly 

 augnlated, the last aboiit two-thirds the total length, ornamented by numerous, 

 indistinct longitudinal ribs, stronger on the upper whorls but dying out on the 

 lowest, and by very fine spiral strise, producing obscure clathration ; spire short, 

 with an obtuse apex ; suture well-marked ; mouth oblong, angulate above ; canal 

 wide, very short. 



Dimensions. — L. 8 mm. B. 4 mm. 



Distrlhutlon. — Recent: Finmark, Lofoten Islands, Iceland, Greenland, north- 

 east America. 



Fossil : Butleyan Crag : Butley (A. Bell). Icenian : Bramerton, 

 Horstead. Iceland Crag. 



Pleistocene : Bridlington and Scotland, fairly common ; Uddevalla. 



Remarks. — The only occurrence in the Red Crag of this northern Bela hitherto 

 recorded is that by Mr. A. Bell, who found it many years ago at Butley. The 

 specimen here figured is from the Icenian deposit at Horstead. There are several 

 others, imperfect, under this name in the Norwich Castle Museum which were 

 obtained at Bramerton. There seems some difference of opinion as to the correct 

 position of this form, Dr. Posselt considering it a variety of B. hicarinaia; 

 generally, however, it has been considered a distinct species.
