looks pretty familiar, first thought it's Jorunna funebris, but it's not
checked Coleman, Debelius, Gosliner et al., Colin & Arneson and one Japanese guide (don't have all of them), also, looked a bit in the seaslug forum, but may have missed it
any ideas ?
Jorunna funebris has a fuzzy texture and a definitely simpler head. This one is a puzzler, but the structure of the head will probably be the clue. It looks like the head of a Polcerid on a chromodorid body. I'll see what I can find. I'd send it to Bill Rudman, anyway.
Cheers,

I think I've got it...it's a Trapania, undescribed...you should let Bill know, as the range will be quite increased.
