Notes on South African marine Mollusca

In the course of my studies on South African Mollusca I met with the following interesting problem concerning the venerid bivalve Sunetta ovalis. The name Sunetta ovalis (Sowerby, 1892), for a long time applied to a well-known recent species from the coasts of South Africa, proves to be preoccupied by Sunetta ovalis Martin, 1880. The last mentioned species was described originally from Miocene layers in West Java.
