First picture, top row is Cronia margariticola (Broderip, 1833), except possibly the second shell, which could be something different.

First picture, bottom row is a small Thais, but I can't quite place the species. Possibly Thais hippocastaneum, but I'm really not sure.

Second picture is a Mitrella species (family Columbellidae), perhaps Mitrella venulata (Sowerby, 1894)

Third picture appears to be Turbo natalensis  Krauss, 1848.

Mark, email me. I'd like to discuss something with you.  PaulCyp@cox.net
