Diagnosis (after Deichmann, 1958): Soft-skinned forms with numerous cylindrical feet, forming a distinct ventral sole, sometimes arranged in three broad bands; dorsally numerous minute papillae, not conspicuous, rarely forming low warts. Tentacles more or less terminal in position, often bushy, adapted for plankton catching. Inner anatomy not remarkable; certain species with numerous stone canals in one or two tufts on both sides of the dorsal mesenterium, others with a single large one attached to the right side; usually one Polian vesicle; gonads as divided threads in a tuft behind the low calcareous ring; Cuverian organs present in some forms. An external layer of tables usually completely lacking, though vestiges of tables sometimes found in young individuals of certain species. The inner layer consisting of small rods or plates, smooth or spinous. Ventral feet with large end plate and walls supported by rods or plates of same size as those in the skin, rarely special supporting rods or perforated plates present. Dorsal appendages with reduced end plate or none, and often more curved, shorter rods. In some species, rods present in the cloacal retractor muscles and in the respiratory trees. Color dull gray, dark brown, olive green or black with or without two rows of dark spots and darker anterior and posterior end.
