REMARKS. This small (up to 1.5 cm in the height and the diameter of the tentacular crown) species occurs on both tops of the Piip Volcano together with larger Corallimorphus cf. pilatus and small Sagartiogeton rufus . The specimens are white, translucent; longitudinal strips of white filaments or gonads are visible through the cylindrical column. The pedal disc is expanded and wider than the column, often forms a kind of lobes and outgrows characteristic for pedal laceration. This species does not have discal tentacles characteristic for Corallimorphus ; there are four cycles of marginal tentacles arranged hexamerously. Sometimes they occur directly among the bacterial settlements on the seeps. Several specimens have been collected. The greatest depth recorded from a photograph for this species is 1053 m (on the dead glass sponge Farrea sp. ).
