Hexasaturnalis octopus
Named by Dumitrica & Hori.
Diagnosis: Hexasaturnalis with eight-spined ring.
Original description: Shell spongy, ellipsoidal when preserved. Ring symmetrical, subcircular or elliptical, rounded on the inner margin, octagonal on outer margin, with a spine at each corner. Inner margin without auxiliary spines. Middle part of ring more or less constricted in the vicinity of contact with polar rays. Outer blades of ring well developed especially at proximal part of ring. Spines usually strong, four-bladed, pointed; peripolar spines longer than distal spines, the latter rarely extremely short. Commonly distal spines closer to each other than to peripolar spines.
Original remarks: This new species differs from the other species of the genus Hexasaturnalis in the number of spines.
Etymology: From the Greek octo - eight and pous, podos foot, referring to the number of spines; noun.
