Note 108 — 3. Genus—TETRACLITA. Pl. 10, 11.

I have seen three separate lots of this species all from the Cape of Good Hope; one lot was collected by Dr. Krauss, at Algoa Bay, and I strongly suspect is the species described by him in his ‘Südafrikanischen Mollusken’ as Conia porosa. If the species, figured by Chemnitz, and mentioned in a note (p. 329), under T. porosa, be the present species, the specimens probably did not come from Tranquebar, on which point Chemnitz speaks only from memory. I have seen one specimen ticketed New South Wales, it is possible, considering the case of T. rosea, that this may be correct, but I should like to have further confirmation before giving it as a habitat.
