Dear Kevin,
This is the pleurobranch Berthella martensi. I wasn't sure they were actually mating so I 'blew up' your photo [see alongside] to check. They definitely are mating. You can also see the nicely coloured gill - yellow with black edges - along the right side of the upper animal. The position of the gill is why pleurobranchs are often called 'side-gilled slugs'.
Best wishes,
Bill Rudman
