white, which is porcellanous on the pillar and in the mouth. Spire 

 somewhat tall, conical, with hardly convex profile-lines. Apex 

 small, pellucid white, consisting of three compact, turbinated, 

 slightly swoln, smooth whorls, the extreme tip of which is very 

 small. Whorls 9, conical, almost straight-sided, not constricted 

 below, with a short rounded base. Suture linear, scarcely im- 

 pressed, but distinct from a slight prominence of the subjacent 

 whorl. Mouth oval, short, not expanding, channelled above but 

 not in the lip ; the canal at the pillar is narrow and deep, it is 

 inclined to the left and widens as it advances. Outer Up nearly 

 semicircular, but its curve is slightly flattened above and in- 

 tensified in passing round to the base ; it has a little way within 

 the mouth about 10 teeth, of which one at the top, two in the 

 middle, and one at the edge of the canal are strongish ; the 

 others are small, but all run some way into the mouth. Inner lip 

 well reverted and thickened, with an abrupt edge across the body; 

 on the base and down the pillar it leaves a small umbilical chink 

 behind it ; just within the mouth it bears a few flattened tubercles, 

 which vary in number and size; the tip of the pillar is well 

 flanged along the canal-edge. — L. 045. B. 0*22.

None of the Nassas of our seas resemble this species, differing 

 as it does from them in its narrow compact form and in its 

 sculpture. Judging from figures, N. glabrata, A. Ad., from the 

 Pacific is a good deal like in many ways, in some of its forms 

 especially. Amidst the inconceivable multitude of Ligurian 

 Tertiary forms figured by Bellardi it seemed probable that this 

 species might be found,- but nothing satisfactory presents itself 

 there, nor elsewhere has the search among Tertiary fossils been 

 successful, though diligently prosecuted. I do not attempt a 

 comparison of it with N. semistriata, Broc, nor with N. labiosa, 

 J. Sow., nor with the N. corniculum, Olivi, nor with the N. tri- 

 fasciata, A. Ad., nor with the N. Gallandiana, Fischer, for the 

 relation of these species has become more and more impossible 

 for off-hand treatment.
