Description

Description. Zooids are flattened and firmly adherent to the substratum. They are joined end-to-end in linear series with frequent lateral and bilateral branching (Figs. 2 a, c, d). The dorsal orifice is surrounded by a squarish chitinous rim with a single spine at each corner. As zooids age the chitinous rim becomes taller, forming a distinct peristome, and the sides peel back as flat scale-like protuberances. Dorsal body spines seem to occur most often on older zooids, often in pairs to form a double row (Fig. 2 e). Hibernaculae form directly from functional zooids as the walls thicken, the polypide degenerates, and the internal space fills with yolky cellular material (Fig. 2 b)
