Shell grayish white, thin, cylindrical with abruptly sharpened apex, twelve pounded whorls and numerous slightly elevated thin sharp varices; nucleus translucent, white, polished, three-whorled; subsequent whorls spirally sculptured with ten to twenty slightly raised extremely fine flattened threads about half as wide as their interspaces, uniformly distributed over the surface and of uniform size; transverse sculpture composed by the fine sharp thin reflected and anteriorly convex varices, numbering about twenty-eight on the last whorl and slightly marked on their concave posterior faces by the extension of the spiral sculpture; whorls and base beautifully rounded; suture distinct but not deep; lip not continuous over the body; line of the varices from one whorl to another in most cases continuous, over the whorl arched forward a little; aperture nearly circular, pillar very thin and not differentiated from the rest of the margin. Lon. 7.25 mm; of last whorl, 2.5 mm; max. lat., 2.5 mm.

A very small shell, to about 8mm, known mostly from off Key West, Florida, at depths ranging from 115 to 230 fathoms. It has 12 to 13 whorls and 26-28 low, thin blade-like costae on the body whorl. There are numerous, very thin spiral threads but no axial threads. This species is characterized mainly by its unique profile, the first three whorls being very small but the fourth one enlarging markedly. The effect is similar to the profile of E. angulatum. The following whorls grow at a steady 18 degree angle. There is no basal ridge and the umbilicus is hidden.

Caribic. Off Cuba. Also East Atlantic: Canary Islands.
