Sole ossicles: throughout sole rare, small, smooth, thin, irregularly shaped rods and perforated plates, up to 10 perforations, up to 240 μ m long, sometimes as regular 4-holed plates with bluntly spined margin, sometimes surface knobs, up to 180 μ m long; near margin of sole and peripheral tube feet thicker irregular rod-plates and very thick irregular perforated plates, up to 300 μ m long. Tentacles: largest tentacle trunk ossicles predominantly smooth perforated plates, irregularly oval, large central perforations grading to numerous small close ones near margin, finely denticulate margin, plates up to 520 μ m long; some thicker plates with large perforations, plates up to 300 μ m long; few rod-plates, up to 300 μ m long.
