their edges curled laterally so as to appear from above rounded 

 and slightly flattened, lamellae numbering about nineteen on the 

 last whorl; under the microscope the spirals in the interspaces 

 appear as raised flat threads, a little stronger than in E. minutis- 

 simuni; each whorl usually also has a single heavy, rounded 

 opaque white varix which on the body whorl marks the termina- 

 tion of the outer lip, but one shell has two additional varices on 

 the last whorl, all three being on the latter third of the volution; 

 all the sculpture extends to the base of the shell, aperture round, 

 lip thickened, continuous. An incomplete shell of six whorls 

 measures 7X3 mm. The style of sculpture resembles that of the 

 recent E. gracilentum Gould. Our shell can be recognized by its 

 many low lamellae, fine spirals and rounded white varices.

Shell rather broadly conic; apex lost, remaining whorls six, 

 convex, adorned with blade-like lamellae, thirteen on the last 

 whorl, which are not denticulate at the shoulder nor hooked at 

 the suture, but simple and continuous or subcontinuous, from 

 whorl to whorl; the lamellae appear to be made up of a single 

 sheet each ; spirals nearly obsolete, exceedingly faint even under 

 strong magnification; the interspaces shining and polished; suture 

 deep; aperture rounded; lip thickened, the thickening interrupted 

 at its contact with the body whorl. Length of decollate shell 

 6.25, greatest width 3 mm. 



The broader basal whorl, more rapidly tapering spire, and 

 blade-like, subcontinuous, simple, not toothed lamellae differenti- 

 ate this species.
