B). The body is divided into a head, a trunk and a foot region. The head is large, especially in the immature specimens. The dorsal part of the trunk has distinct longitudinal folds in the integument and the foot is composed of two pseudosegments. The corona is complicated, consisting of a continuous circumapical band that encircles the buccal field. A pseudotrochus is formed by four rows of long, stiff cirri. All cirri curve away from the mouth opening. Two other paired rows of cirri are located closer to the mouth opening. These cirri are shorter and curve towards the mouth opening. The buccal field is small and comprises a group of motile cilia around the mouth. The brain is large and saccate. Cerebral glands were not identified. A large eyespot is located on the ventral side of the brain. A pair of dorsal antennae is located dorsally on the head. Lateral antennae are located laterally, slightly behind the mid length of the trunk. Each antenna opens inside a small depression in a prominent wingshaped elevation formed by the integument (
