Dear Valda,
I think it is Janolus capensis but i must say my opinion is not very expert on South African janolids especially when Terry Gosliner says there are few external differences between Janous capensis and Janolus longidentatus Gosliner, 1981. One feature mentioned by Gosliner (1981) is that J. capensis has a translucent whitish body with a white edge to the foot, which can certainly be seen in the lower photo. Another useful character is the shape of the egg mass and the number of eggs per capsule. Have a look at my notes at the top of the page. A photo of any eggs would be a nice thing to add.

Best wishes,
Bill Rudman.
