The first one resembles a Plesiotrochus, perhaps P. sowerbianus (Gould, 1850). Regards

Dear friends, we are a bit puzzled with this pair of gastropods. The
first one is absolutely unidentifiable by us. To the second one, we
understand it's a Gibberula or something close to. Unfortunately, we
don't have access to the studies made by Killburn or Lussi & Smith on
the Cystiscidae of South Africa and SW. Indian Ocean.

If anyone had an idea...
