Phyllidiella cf. annulata from Christmas Island

From: W.B. Rudman
Here are some information and photos on an animal which seems to be a colour form of Phyllidiella annulata from John Hicks' Christmas Island, Indian Ocean collections.

In typical specimens of P. annulata there are a row of distinct rings down the midline of the mantle, while in this animal the rings tend to coalesce. One other point of difference is that Brunckhorst considers that in P. annulata there is no continuous pink edge to the mantle. Despite these differences, no other species has this black-centered ring pattern.
Best wishes,
