This little species exliibits a distinct epidermis and has no 

 teeth in the aperture. A slight sinus is visible in the outer 

 lip near the suture.

Like £". suhfiavescens and E. suhhyalina this species is 

 cjlindrical, smootli, and very glossy, but differs in having 

 only two teeth in the aperture.

The mouth of this minute species is much closed up by the 

 three denticles, which converge towards the centre. One on 

 the outer lip and one on the columella are thick and rounded,
