Abactinal skeleton is an irregular, open meshwork. Papular areas are larger than abactinal plates, containing 1 to 9 papulae. Abactinal spines clavate, bluntly pointed, serrated distally, and arranged in two or more series. Intermarginal series extends to 1/3 to 1/2 of R. Pseudopaxilla widely separated from each other. Superomarginal, inferomarginal, ventrolateral, and adambulacral plate is each with 5 to 20 spines. Ventrolateral series are multiple. The ventrolateral series next to the innermost series is the longest. Subambulacral spines arranged in two or more rows. Furrow spines 2 on most adambulacral plates in a vertical row.
