. Stolons creeping on external surface of polychaete tubes, giving rise to irregularly-spaced hydrothecae. Hydrothecae consisting of a short basal portion, adnate to substratum, and a much longer free part (up to 2.5 mm high), sharply bending away from adnate part. Most hydrothecae with several widelyspaced renovations; hydrothecal aperture circular, rim even, though indistinctly everted. Upper side of adnate part provided with variable number of transverse striae. Coppinia absent.
