Bergh in Carus, 1889
Mobile, aggressive aeolidaceans, having a cleioproctic anal position (within the foremost ceratal arch derived on the right side from the left digestive gland). All the branches of the digestive gland take the form of arches (often called horse-shoes), sometimes reduced to simple rows at the rear. Propodial tentacles and long, agile oral tentacles are present; the rhinophores are smooth, sometimes with one or more bulbous swellings. The penis is short, conical and unarmed. Two receptacula are present.
The jaws may be smooth-edged or bear denticles on the cutting edge. The teeth of the uniseriate radula have a slender median cusp and faint lateral denticles, sometimes lacking.
