Dear Bill & Allen,
Concerning message #12934: Now with the Easter holidays I have finally had the time to look at some of the sacoglossan messages that have been posted on the Forum over the last couple of month (except the ones that I have been able to answer right away).
The Elysia from Hong Kong is probably E. hirasei Baba, 1955. This species was illustrated as E. viridis on Fig. 25 in Baba's Sagami Bay monograph (1949), and described as a separate species in the Supplement to that book in 1955. The black lines on the head are identical, and colour pattern also fits. This will be a new record from Hong Kong, but I also found this species in Phuket, Thailand many years ago (1986 I think). I found it on some thin filamentous algae, possibly Rhizoclonium, and I was able to keep them alive by feeding them Chaetomorpha after my return to Denmark. Unfortunately they died over a weekend, so I do not have preserved specimens.

Thanks for that - now that you tell me - the black markings in the painting in Baba (1949) are indeed identical to the one from Hong Kong. It is a very distinctive colour pattern.
