To size: To 100mm. Shell Structure: Thin but not fragile. Equivalve: Equivalve. Equilateral: Slightly inequilateral, beaks just infront of midline. Tumidity: Inflated. Outline: Broadly oval becoming subquadrate-oblique with a long almost straight posterior margin contrasting with more narrowly rounded anterior. Contour: Umbonate, posterior angle weak.
Sculpture: 20-22 strong radial ribs, each carrying a row of narrow spines arising from the midline of the rib. On the posterior angle and posterior area the spines are long and resemble thorns. In the largest shells the spines on the anterior and middle area become more broad with the upper faces excavated and the tips bending to the posterior. The concentric sculpture is weak and shell other than spines appears rather smooth. Margin: Deeply crenulated, interlocking ends of ribs and interspaces.
