Dear Valda,
A number of species of Armina were described earlier this century from South Africa. Unfortunately most were described from from preserved specimens and not surprisingly their colour in preservative had become 'blackish with white lines'.

I think they will only be sorted out when their anatomy is studied. from a quick look at the descriptions, your animal seems to differ from them all in having relatively few longitudinal mantle ridges (usually about 30). I am pretty sure it is a species of Armina, but again, a closer look at the anatomy would be needed to confirm that.
Best wishes,
Bill Rudman.
