Hi Bill,
I found a couple of pictures in my files that look like Bernard Picton's Elysia sp. 11. I found the first one (119702) in the Florida Group of the Solomon Islands in November, 1997. It was 21 mm long, depth not recorded. I photographed the second one (89901)in Tonga in August, 1999. It was also 21 mm long and five meters deep. Whatever it is, it seems to have quite a wide distribution.
Best regards,
Mary Jane

Thanks Mary Jane,
It certainly has a fairly distinctive shape and colour. It reminds me of Elysia trisinuata Baba 1949, from Japan, but that species was said by Baba in the original description to have papillae on the parapodia and rhinophores. In a later description (Abe, 1964) the papillae are not visible in the illustration and in the text are said to be 'minute'.

Perhaps someone familiar with the Japanese fauna can help us out.

Best wishes,
Bill Rudman
