Shell subcylindrieal, perforate, opaque, yellowish white, finely 

 and closely obliquely costulated throughout ; spire ovate, apex very 

 obtuse ; whorls 8, very slightly convex, the last three of nearly the 

 same diameter, very gradually increasing, the last whorl slightly 

 ascending near the aperture ; suture somewhat irregular and pre- 

 senting a puckered appearance caused by the meeting of the costulse ; 

 aperture sinuately semioval, glossy within ; paries armed with a 

 large curved lamella extending far within the aperture and forming 

 a deep canal with the outer lip, the lamella somewhat overhanging 

 the canal ; a thick tooth is situated about the centre of the outer 

 lip near the margin, and an expansion or plication is placed behind 

 the columella far within the aperture; labrum thickened, expanded 

 and reflexed ; a pit or depression behind the labrum corresponds 

 with the tooth within. Length 11| millims., diameter of the three 

 equal whorls 5|, diameter of aperture 3g.

This species at first sight appears to be a perfect miniature of E. 

 crassilabris ; but, besides its diminutive form, it is more cylindrical 

 than that species, and the dentition of the aperture presents various 

 differences.
