Mystery animal is Polycerella emertoni?

Greetings,
Here is a second picture of what I presume to be a nudibranch found on the bryozoan Bugula neritina.
Thanks for your consideration,

Pederson, E., 2000 (Jan 25) Mystery animal is Polycerella emertoni?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1771Dear Eric,
Your second picture is definitely not of a leptonid bivalve, as I tentatively suggested from your first photo.
I am pretty sure that it is Polycerella emertoni which has a pair of smooth anterior rhinophores, 3 relatively large gills, and a pair of relatively large smooth papillae just behind the gills. It has some other smaller papillae but I can't see these in your photos. It feeds on bryozoans.
If I'm wrong I am sure someone will let us know.
Best wishes,
Bill Rudman.
