Four equatorial spicules compressed, nearly rectangular, forked; one pair of opposing equatorial spicules with two, other pair with four horns; two opposite spicules of longitudinal axis about one-third longer and broader than those of transverse. Sixteen smaller spicules of same form, also forked, eight tropical half as large, forked twice; and eight polar spicules scarcely one-fourth as large as two longitudinal spicules, forked once. Length of equatorial cross: 0.36 mm, breadth: 0.26 mm.
