Dear Bill,
Thanks for the information about Aeolidiopsis. Here is some more information on the egg masses. This photo was taken on the 21 July 2002 showing the brown speckled form laying an egg ribbon.
Best Regards,

Dear Nishina,
Thanks for this photo. The egg ribbon in this photo is much more folded than in the earlier photo. This suggests to me that the variation you showed between the egg ribbons of the brown speckled animal and the white ones may just be part of the normal variation in the species, which would support my suggestion that they were one species.

I have also included a close-up of the midregion of the animal because I think it shows (in ring) the anal papillae on the back just above the line of cerata. This is the position of the anus in A. ransoni, and combined with the smooth rhinophores shown in your other photos, makes me pretty convinced that this is A. ransoni.
Best wishes,
Bill Rudman
