According to Peter Brueggeman (in Underwater Field Guide to Ross Island & McMurdo Sound, Antarctica), Heike Wagele considers this photo to be of either Notaeolidia schmekelae or Notaeolidia gigas. At such a large size (about 10 centimeters long) she considers it to most probably be N. schmekelae but could only confirm that identification with a look at the reproductive system. N. schmekelae is the largest species, preserved animals of over 135mm being recorded. It had up to 4 rows of cerata around the mantle edge.See Notaeolidia depressa for a discussion about this Antarctic genus.
