Shell thin, white, elongate, with fifteen rounded whorls (nucleus lost) each ornamented with about twenty-five thin sharp varices each of which has a small triangular sharp point half-way from the suture to the periphery; behind these the interspaces are smooth to the suture; in front of the varical points the surface is sculptured with raised flat-topped threads with wider intervals between them and numerous still finer spiral striae; the spiral sculpture does not crenulate the varices; shell imperforate, without basal disk or cordon; aperture small, lip thin, narrow, hardly reflected, tortuous and a little patulous at the anterior end of the. axis; suture very deep. Lon. 30.0 mm, max. lat. 6.5 mm.

A deep water species occurring from off North Carolina to near Cuba at depths ranging from around 50 to 750 fathoms. It has 16-17 whorls which are attached and angled shallowly from the apex at 15 to 22 degrees. May grow to 30mm and has about 24 costae on the body whorl. Very similar to E. dallianum and E. fractum, it differs by having spiral sculpture of numerous fine threads with some microscopic axial threads. Few examples of are known of this rare species.

The specimen procured was fresh, but without the soft parts. This beautiful species somewhat resembles Verrills figure of E. dalliana, but is longer, much more cylindrical, and has strong spiral sculpture which is wanting in that species. The upper fourth of E. babylonia, which would about correspond in size to E. dalliana, has the costae more sparse, thin and erect, the whorls much rounder, and the suture much deeper than in that species. None of the other species described from deep water are much like it.
