« Aperture oval, round; apex protruding beyond the posterior margin; fissure ending at the summit, with raised edges. Height 1/3 lower than the largest diameter. About 32 coasts, all of equal thickness, crossed by concentric cords regularly spaced and forming a mesh in the apical area. Sculpture generally weaker than in E. conica [syn. of fissura], a species to which it can be compared. » – P. Piani: “Catalogo dei Molluschi conchiferi viventi nel Mediterraneo”, Bollettino Malacologico anno 16, may-june 1980, page 118 footnote 3.
