Berthella ocellata from Mediterranean

Again a photo taken by Wolfgang Seifarth this summer in Italy, depth 15m. Is it Berthella ocellata  (delle Chiaje, 1830)?

Dear Erwin,
I have never seen this species alive or in photographs, but from published accounts I am pretty sure your identification is correct. After the variability of Berthella stellata, it's nice to see a Berthella with a distinctive colour pattern.

Any chance of a few more locality details and size perhaps?
Best wishes,
Bill Rudman.
