"An unusual individual in which the pustules on the mantle are not clearly grouped into three longitudinal rows. But this could be an artefact of its posture. There is a single large pustule immediately behind each rhinophore (called a rhinotubercle). There is a series of prominent black longitudinal dashes forming a stripe on the foot sole."
Comment from Richard Willan
An unusual individual in which the pustules on the mantle are not clearly grouped into three longitudinal rows. But this could be an artefact of its posture. There is a single large pustule immediately behind each rhinophore (called a rhinotubercle). There is a series of prominent black longitudinal dashes forming a stripe on the foot sole.
