 You are very welcome Mila. By the way you (or we) could perhaps also place a copy of that image on the page Polyceridae ( a fmaily of nudibranchs) because that species ... Triopha catalinae J. G. Cooper, 1863 sea-clown triopha ... is listed there since it belongs to that family. Since the species name Triopha catalinae is linked to a non-existent page, we could even (if we felt like it to) start a new page for that species. (By the way, in English the word nudibranchs is spelled without the ""e"".) I did try to look up your images on Bill's site, but I was not able to get to the exact page on a lot of them. just a list and at the present time  I did not take the time to try to track it down any further. Maybe I will do that later.   "
