Another white chromodorid with a yellow or yellow-orange border. On the inside edge of the yellow border is a band of opaque white spots representing the subepidermal mantle glands. There are usually two or three orange spots on the mantle and sometimes eight or more, but they can be absent. The rhinophores are tipped with orange. The gills are usually orange-tipped but sometimes the orange is absent. Anatomy and taxonomy discussed in Rudman (1985). It grows to 15-20 mm in length.
