Wow what a beautiful and complicated aeolid nudibranch. Members of this family are characterized with the curious, highly private, I would think, position of their anus. I am not sure I would feel comfortable about someone characterizing me about the location of my dernier, although it is most likely the same as yours.
Internally the radula is characteristic also - a single row of rachidian teeth with long basal limbs and a large pointed cusp flanked by several denticles.
The body has irregular red longitudinal lines along the edge. Opaque white spots cover the body, head, oral tentacles and rhinophores. The bases of the brown cerata have black dashes. Their tips are white. Very cool.
This one is new to me. Thanks Jim.

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
