 and this may account for the above expression. In other respects 

 I can see no difference between tlie original description and the

Shell small, oval, with a heterostrophe embryo, prominent and 

 acute spire, somewhat elongate body-whorl, comparatively large 

 and entire aperture, with a strong tooth near the posterior end 

 of the columella, and a faint umbilical chink. Apical angle about 

 thirty degrees. Embryo rather small, consisting of aljout one- 

 and-a-half smooth convex whorls enrolled in one plane in the 

 heterostrophe portion, which are partially hidden by being 

 immersed in the succeeding whorl. Heterostrophe portion of 

 embryo followed by about another half whorl, which is smooth 

 and convex, and completes the embryonic whorls. Spire-whorls 

 three to four, regularly convex, with a well-defined and slightly 

 channelled suture ; whorls gradually increasing at first but 

 comparatively suddenly expanding into the much larger and 

 somewhat elongate liody-whorl. AjDerture oval, entire, very little 

 less than half the length of the shell, somewhat effuse anteriorly. 

 Outer lip smooth internally, with a thin margin, the slight 

 sutural channelling being most noticeable at its junction with the 

 body-whorl. Inner lip concavely arched, reflected outwardly 

 towards the anterior end. Columella bearing one stout oblique 

 tooth, which is situated rather high up, being immediately 

 opposite the very small and narrow uml)ilical chink, or slightly 

 above the middle of the aperture. Spire-whorls ornamented with 

 about twelve comparatively broad and flat spiral threads, with very 

 narrow and shallow intervening grooves. On the body-whorl the 

 spiral threads become more numerous, amounting to about twenty, 

 and at the same time become considerably broader bands, and tend 

 to be faintly subdivided by very much fainter, narrower, and
