set, fine, microscopic lines o£ growth. Colour translucent white, 

 with a glossy surface. Apex is largish, but the first whorl con- 

 tracts a little, and the extreme tip, which rises slightly on one side, 

 is very bluntly pointed, or at least not perfectly rounded. Spire 

 conical, symmetrical, with a slight sudden contraction toward 

 the top. Whorls 9, of very regular increase ; they are all small 

 and not in the least convex, except the first three, which are 

 slightly so. Suture a little oblique, linearly impressed, except in 

 the case of the first three whorls, which slightly contract into the 

 suture both above and below. Mouth a long oval, in its direction 

 straight, with an open gutter in front. Older lip a little flatly 

 arched ; its edge retreats very much above, forming a deep wide 

 sinus : at the periphery it makes a very prominent advance; beyond 

 this it scarcely retreats, but across the base projects with a very 

 prominent patulous lip. Inner lip : there is a thin defined glaze 

 across the flat body ; tlie pillar is long and concave, with a rather 

 broadly reverted lip which passes very gradually over into the 

 patulous basal lip. H. 0'14. B.0"04. Penultimate whorl, height 

 0-02. Tip of apex 0-008. Mouth, height 0-048, breadth 0-025. 



This species is represented by eight specimens, all nearly of the 

 same size, but they look hardly quite mature. It ditfers from E. 

 cylinclrata in being a little broader in form, more conical, and 

 less cylindrical ; the suture is distinct. The mouth and the apex 

 in all their details are diff"erent.

Shell. — Thin, hyaline, glossy, rather narrow, with a bluntish 

 rounded base, a symmetrical spire, a biggish flattened tip, slightly 

 convex whorls, a well-marked suture, and a short oval mouth. 

 Sculpture. There are microscopic hair-like but slight lines of 

 growth, with occasional stronger mouth-edge scars at irregular 

 intervals, but with a recurrence of one series of them on succes- 

 sive whorls : these scars are like cracks in the substance of the 

 shell. Colour hyaline white, scarcely clouded, and with a glassy 

 surface. Apex rather large and blunt, the tip being flattened 

 down and spread out, with a very slight rise on one side of the 

 flatly rounded summit. ^S^^zVe straight and symmetrical. Whorls 

 8|, of regular increase ; they are a little large and slightly con-
