Oblique basal view. c. cryptocyst, op. operculum (open). Description. Zoarium bushy (type colony, 12 cm. high, 8 cm. broad) composed of very delicate feathery branches. Rootlets forming a short, thick stalk. Zooecia without a digitiform process.

Opesia short, broader than long, roughly triangular, proximal border straight, orifice at apex of triangle, outer basal angle of triangle occupying the prominent outer distal corner of zooecium. Inner basal angle with a curved cryptocyst (Fig. 31 A). Spines, six or seven, four on distal corner, two or three in transverse row on basal surface. Fertile zooecia a little broader than non-fertile, with eight to ten spines more evenly distributed in a transverse row (Fig. 31 C), recognizable by their shape, and by the D XXII 14
