Sculpture of ca. 40 regular primary radial ribs (Figs 32, 33), with rounded profile; secondary ribs initially rather fine, gradually increasing to size of primary ribs at margin; transverse, semilunar, low nodes as thickenings at intersection with radial sculpture, disposed along ribs in regular spaces equivalent to ca. 1/2 of ribs width; nodes continuing between ribs forming series of squared pits; interspaces between successive radial ribs ca. 1/3 their width; ca. 60 scales along ribs close to median line. Selenizone well-marked, as wide as fissure; edges barely taller than radial ribs, continuation from those of fissure, with sharp edges (
