Shell heavy, small, laterally compressed, elevated, the height being about 75% of the length. Base narrow ovate. Anterior slope convex, posterior slope slightly concave below the apex, then straight to the margin. Apex high and at about one fourth of the length of the shell from the posterior end. Anal fasciole very narrow, formed by numerous closely-set incremental lamellae. Fissure about one sixth the length of the anterior slope and turned to the left. Sculpture consists of very compact, almost equal radiating ribs, beaded by elongated and very closely-set nodules concentrically arranged but not linked to form concentric cords. Interior of shell polished, with the muscular impression strongly marked. Length 4,5-5 mm; Width 3,5 mm. Height around 3,5 mm.

This species is close to E. solidula from the Mediterranean Sea, both having the same type of sculpture. They differ quite sharply in shape, E, nordica being much compressed, with a narrow oval base, while E. solidula has the shape of a broadened cone, with a much wider base. In addition, E. solidula is lower, its height being half or less the length and has the apex placed farther from the posterior end.
