There is a line down each oral tentacle which extend onto the head a join in the midline running back between the rhinophores as a single median line, which stops at about the heart. There is a medio-dorsal line along the posterior foot and a white line along the dorsal face of each ceras. The rhinophores have 3 rounded ridges or 'ring-shaped swellings'.
