The shell is of a rather slender turreted shape, not particu- 

 larly thin, perfectly smooth, very slightly translucent, and of 

 an uniform polished porcelain white.. Its spire, which tapers 

 to a rather obtuse point, is composed of about nine volu- 

 tions besides the heterostrophe apex, and is divided by a 

 profound and scarcely slanting suture. The whorls, whose 

 longitudinal increase is rather slow, are short (that is to 

 say, only about half as high as they are broad), and, ex- 

 cept one or two of the earlier ones, so flattened that their 

 slant is almost uninterrupted throughout the shell : never- 

 theless, a slight swell is occasionally apparent near the 

 base of the last turn or two. The body, which occupies 

 about a quarter of the length of the shell, and is about 

 equal in length and breadth, is subangulated at the com- 

 mencement of its extremely abrupt, yet convex, basal de- 

 clination. The mouth does not much exceed a fifth of 

 the total length, and is destitute of any sculpture whatso- 

 ever. It is acutely contracted posteriorly, but its general 

 shape is subquadrate, as the long and straight pillar forms 

 rather more than a right angle with the convex but almost
