The musculature is weak. It comprises about 30 thin ribbons arising from each siphon. Near the gonads the ribbons disintegrate to make anastomosed fibres. The body wall is transparent. The siphons are red as is the external tunic. The tentacles are not numerous, about 10 of two or three orders, located anteriorly in the oral siphon. They are poorly ramified and the smallest are simple (
