Upper: Northern end of Vancouver Island the first week of October diving around Port Hardy and Browning Pass, British Columbia, Canada. October 2003. Photo: Bruce Wight.
Lower: Vancouver, Canada. divesite "Flemming Bay", August 12, 1997. Size about 3 cm, Depth 12 m. Photo: Frank Gloystein. Apparently this is a photo of a pale colour form in which yellow markings are a pale cream.

The body and mantle are translucent white. The mantle is covered with long pointed papillae. The rhinophores have a relatively short stalk and a long recurved lamellate club. Both the gills and rhinophores are translucent clear but the tips of the gills and rhinophore club are suffused with a yellow tinge. There is an opaque border to the mantle which is usually a milky yellow. The tips of the papillae are usually of the same colour. In some specimens the mantle border and tips of the papillae are cream white rather than yellow.
