Body elongate, fusiform, slightly tapered and rounded posteriorly; up to 60 mm long (preserved, excluding tentacles); body wall calcareous, rugose, not parchment-like; 10 dendritic tentacles, ventral pair small; tube feet in radial series, retractile, dorso-lateral radial series variable size, zig-zag to double discontinuous rows, 3 ventral radial series close zig-zag to double irregular rows; calcareous ring lacking posterior prolongations, radial plates with narrow sub-rectangular anterior projection, interradial plates with strongly tapered anterior projection, all plates with rounded notch posteriorly; single polian vesicle; gonad tubules long, thin, unbranched. Mid-dorsal body wall ossicles thick perforated plates, spinous cups; plates irregularly oval to elongate, predominantly more than 2 perforations wide, plates up to 528 µ m long, lacking knobs over most of plate, but frequently knobs, spines and thick low spinous spire above one end of surface of plate, about 160 µ m high; irregular deep to shallow cupped crosses and cups, 48–88 µ m long, blunt to pointed spines on rim, 4–8 perforations, perforations frequently small, no cups closed by bridges across rim.
