Similar to E. ci/lindreUoidea, but coii'^iclerably larger, with 

 lOi- 11 whorls, finely, not very closely costulated. The aperture 

 is very differently shaped, being oval, considerably higher than 

 broad, with the subtubular portion in the riglit upper corner 

 ahnost cut off by a vertical parietal lamella and a thickened sub- 

 angular plait inside the outer margin ; both of these plaits are 

 twisted inside, so as to appear from the aperture like additional 

 teeth, there is also an internal obliquely descending columellar 

 fold and another external lamella just visible from the front; 

 peristome expanded throughout, deeply sinuate at the angle ; 

 last whorl free for a short distance behind the peristome, cora- 

 pressed and bluntly subangulate at the base. 



Length 9, breadth 2|, height of aperture nearly 2 mm.
