364 PLIOCENE MOLLUSCA. 



whorl ; inner lip forming a glaze on the columella ; canal wide, of medium length, 

 obliquely notched at the end; columella curved, slightly expanded where it joins 

 the canal. 



Dimensions. — L. 65-80 mm. B. 30 — 40 mm. 



Distribution. — Recent : British coasts, principally north-eastern, Shetland, the 

 Hebrides, Norwegian coast as far north as Finmark, and the Lofoten Islands, 

 Faroes, Siberian coast, Spitsbergen, Davis Strait. Dredged to the north of Spain, 

 the west of Portugal, the west of Morocco, off the French coasts of Africa (D. and 

 F.), near the Azores, the Canaries and the Cape Verde Islands. 



Fossil : Waltonian Crag : Little Oakley. Butleyan : Butley Mill. 



Icenian : near Norwich. 



Remarks. — This rare and beautiful British shell, for the most part a deep 

 water form, was reported by Wood with some doubt from the Icenian or Norwich 

 Crag. Unfortunately, of the two specimens figured by him under that name, 

 neither can now be traced. I have found several fragmentary specimens at 

 Oakley, however, which, taken together, justify the inclusion of the name of this 

 species in the fauna of that prolific locality. One of these I have figured, together 

 with a recent example, for the guidance of collectors. Mr. A. Bell informs me that 

 his brother obtained a variety of this species from the Red Crag of Butley Mill.

Specific Characters. — Shell large, ovato-fusiform, spindle-shaped; whorls 6 or 

 7, convex, regularly decreasing in size upwards, the last much the largest ; the top 

 of the spire is obtuse or depressed, except that the apex, which is minute, is pointed 

 and projecting, differing from that of any other form of this group ; suture well 

 marked; mouth ovate, angulate above; outer lip thin, gently curved; inner lip 

 forming a callus upon the columella which in the adult shell is thickened, forming 

 a large tooth or excrescence on the body-whorl immediately below its junction
