 This little species exhibits a distinct epidermis and has no 



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



lip near the suture.

Like E. suhflavescens and E. subliyalina this species is 

 cylindrical, smooth, 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, 

 whilst the third is thin, lamellar, and joins the upper termina-

 dinal lirse on the last whorl do not extend upward as far as
