Hi Bill
I came across this wee nudibranch nudibranch on a dive yesterday. I've not seen this one before but guess it's Cuthona scintillans.

Locality:  Poor Knights Islands, NE New Zealand. Depth: 18 m. Length: 10 mm. 05 November 2005. Rocky reef. Photographer: Ian Skipworth

Your comments would be appreciated.

Cheers
Ian

Dear Ian,
It certainly seems to be C. scintillans. I assume the smaller number of ceratal rows is related to its smaller size. The colur pattern, with the opaque bright white spots certainly deserves Michael Miller's name 'scintillans'. There seem to be distinctive wrinkles on the rhinophores which I assume are because they are somewhat contracted. This  is a valuable contribution to our knowledge of this rarely reported species.
Best wishes,
Bill Rudman
