More on Phyllidiella pustulosa? from Mauritius

Bill,
Fred writes the Phy. pustulosa / annulata slugs are common at Mauritius, (not Philippines where you placed them,) up to 20 m depth. Here are two more photos of others specimens.
UPPER: depth 10m, LOWER: depth 17 m
I will post them at my web-site as Phyllidiella sp.

Note added 7 November 2002: I have identified this as P. meandrina. - Bill Rudman

Dear Erwin,
Sorry for the locality slip up, which I have corrected. The side view showing the edge of the mantle shows it doesn't have the pale edge considered typical of Phyllidiella pustulosa, and one point I should have realised is that P. pustulosa doesn't have the tubercles arranged in ridges, as these Mauritian animals clearly do. They still don't look like typical Phyllidiella annulata. Perhaps they are a form of Phyllidiella zeylanica, which does have ridges and shows some development of the median ridges in to circles. Phyllidiella zeylanica also has a ring of tubercles around the anus which can be seen in both phtos above.

Bill Rudman.
