I only found a single specimen, but it exactly agrees with the type, which 1 found at St. Helena, the reticulated surface being just visible. It was one of the St. Helena-Cape series, i.e. shells which I found at St. Helena, but only on pieces of floating sea-weed, or ,seahorn, which had drifted there from S. Africa. This was my own opinion, and Mr. Smith in his report said there was no doubt about it. They were quite different from the Island shells. Many of them were new species, and the fact of African shells being first found at so great a distance is very interesting. I do not know from what part of S. Africa the sea-horn came, though from the direction of the current it must have been from the eastern side of the Cape, so my finding them at Port Alfred is not so very surprising. The others L found were Nos. 1017, 1040, 1081, 1653, 1081, 1682.
