The eight mouth arms are as long as the diameter of the bell, terminating in club-shaped filaments. There are seven radial canals which link to the ring canal. The bell is pale yellowish-brown with white spots; these are small near the margin but larger over the ring canal. The mouth arms are brown, spotted with white, and the terminal filaments are yellowish.[2]
