Adjoining the inner side of the white marginal band is a band of orange or yellow, which may be broken into spots. There is a medial white band on the translucent foot with an elongate orange spot in it. The gill pinnae and rhinophores are translucent white, with orange pigment at the tips of the rhinophores.
