Description

Shell solid, stretched, conic in form, whorls convex adorned with solid axial ribs roundish in form. Suture very deep and canaliculus. Surface smooth and bright. In the upper part, the ribs (9 on the last whorl) have a sort of auricle that joins the previous rib. Aperture roundish in form. Colour pattern changeable: on a light brown ground there can be seen either streaks or bands darker, mainly near the suture. Umbilicus missing. Protoconch, made by about 4 whorls of spiral, smooth and brown in colour. Locard & Caziot, 1900 described some varieties of this species (minor, major, elongata) without any taxonomic value. The differences with E. turtonis Turton, 1819, unique species similar to clathrus, are mainly due to ribs flatter, to a non uniform thickness, to a suture less deep and usually to a darker colour pattern as far as turtonis is concerned. The adult specimens average measures are around 25-30 mm in height.
