Typical doris shape with an ovate mantle with a broad overlap or 'skirt' which hides the body and foot. The mantle is translucent white with a single row of large, rounded, milky yellow mantle glands running around the mantle skirt some distance from the edge. It is usualy described without a yellow border to the mantle but the specimen illustrated here, and another in Behrens (1991) have adistinct yellow border. The rhinophores clubs are black and the gills are translucent white.
It is reported to feed on the sponge Aplysilla glacialis (Dybowski, 1880) (see McDonald and Nybakken, 1978).
