Hi! I just came across an exciting and important new paper on the mitochondrial gene sequences of the Japanese opisthobranch Pupa strigosa. I was wondering if you might have a photo of this species?
Kurabaysahi, A. & R. Ueshima. 2000. Complete sequence of the mitochondrial DNA of the primitive opisthobranch gastropod Pupa strigosa: Systematic implication of the genome organization. Mol. Biol. Evol. 17: 266-277.
All the best,

I am sure you thought I had lost this message of yours from last October about Pupa strigosa, but as I didn't have a decent photo I put it on my 'shopping list' when I went to Lifou. I asked Jean Tröndlé, a very experienced amateur shell collector, to look out for some, and he didn't fail me. So here is a photo for you. How's that for service!
Pupa strigosa is one of a number of species of acteonid with a pattern of black spots on the shell, and I suspect many records of these species will need to be re-examined. An interesting external feature I noticed in the live animals was the brown median line on the head which is part of the foregut showing through the almost transparent body wall. This is the only species I know of which shows this brown band.
[The locality information I am including with photos from Lifou 2000 is very minimal. As soon as the Station data is standardised I will fill in the details]
