LV-82-1, 55.4166°N 167.2756ºE – 55.4159°N 167.2737ºE, depth 390– 362 m, one specimen collected (sample 7) and six specimens photographed.

REMARKS. Sea anemone with cylindrical column covered with brownish cuticle and rows of tubercles. The tubercles are larger distally. Short bare rose colored scapulus has tubercles. The oral disc and tentacles are orange. The oral disc is wider than the column, up to 10 cm in diameter. The tentacles without mesogloeal thickenings, arranged in five cycles on the periphery of the oral disc, up to 96 in number. The species was recorded on the northern top of the Piip Volcano at depths of 352– 415 m, where it is common: many specimens were photographed, one collected. Two specimens, probably belonging to this species, were photographed on the northern slope of the Piip Volcano at the bathyal depth of 1342–1389 m (not collected).
