Dear Daniel,
I can't see too much from your photo about the shape and size of the cerata, but I suspect the inside cerata in the back row of each clump of cerata will be long and curled. At present I am identifying all with this shape as Moridilla brockii. Yours looks very like the original description. It is possible there may be more than one species involved but so far I can't see any difference in radula shape and general body shape.
Best wishes,
Bill Rudman
