SJiell — Smooth, fusiform, rather thin, with a high, sharp, slightly 

 enamelled apex, a contracted and elongated base, a straight two- 

 toothed pillar, a large mouth, a prominent angulated and patu- 

 lous outer lip, and a strongly marked sinus at the enamelled 

 suture. Sculpture. Longitudinals — the smooth surface is scored 

 with fine hair-like flexuous lines of growth. Spirals — there are 

 some lines in the substance of the shell which are best recognized 

 without a lens : there are also some irregular white lines con- 

 nected with some slight thickening of the glaze ; below the scar 

 of the sutural sinus is an obsolete angulation. Besides all this, 

 the surface of the enamel of the shell is obsoletely tubercled 

 obliquely. Colour rich buff, thinly overlaid with a whitish glaze ; 

 this for some distance below the suture is covered with a dullish 

 buff enamel. S2nre high, conical, subscalar. Apex small and 

 sharp, being originally mamillated, but subsequently eroded and 

 enamelled. Whorls 7 to 8, at the top very slightly shouldered 

 and angulated, then flatly convex. Suture oblique, completely 

 buried in a thick coat of glaze which fills the sutural angle, 

 and which embraces the whole apex. Mouth large, pear- 

 shaped, with a shallow, broad, obliquely truncated canal in front. 

 Outer lip thin and rounded on the edge ; it is cut off from the 

 body by a strongly marked sinus, below which it advances pro- 

 minently into a rounded angle, retreating slightly, but steadily, 

 from this point throughout its whole course ; it is straight and 

 slightly contracted above, roundly angulated and patulous below 

 the middle, straight and patulous and cut off backwards from this 

 point to the edge of the canal. Inner lip scarcely convex above, 

 little concave in the middle, direct with a very slight twist and 

 no swelling below ; near the edge are two narrow, slight, white, 

 very oblique teeth, of which the upper is sometimes absent : the 

 narrow sharp lamina of the pillar-edge in front is the extreme 

 point of the shell. H. 3*6. B. 1"8. Penultimate whorl, height 

 0-8. Mouth, height 2, breadth 0-95,
