Shell small, decollate, with four well-rounded whorls remaining, with a dull surface, white, and rather laxly coiled; suture distinct, deep; axial sculpture of (on the last whorl 13) thin low slightly oblique sharp lamellae, continuous in the depth of the suture and up the spire, making about one-third of a turn around the shell; there is no spiral sculpture (though the edges of the lamellae look more or less irregular, it may be due to wear); the base is evenly rounded without a disk, and imperforate; aperture rounded with a thin slightly expanded margin. Length of four whorls, 9.5; of aperture, 3; diameter, 4 mm. U. S. Nat. Mus. Cat. No. 108015.
Off Fernandina, one specimen.

A fairly rare species known from off of the coast of Florida south to Brazil. Found in depths of 30-325 fathoms. Minutely perforate with numerous bladelike, axial costae. Spire extended, forming an angle of 20 degrees. No spiral sculpture and no basal ridge. Up to 16 whorls attached only by the costae which number up to 19 on the body whorl.
Its closest relative is E. dallianum, from which it differs by being somewhat larger and having fewer but stronger costae on the body whorl.
