I.?Further Additions to Australian Fossil Echinoidea

During the last two years four papers have appeared upon the Australian Cainozoic Echinoids, contributed by M. Cotteau, Prof. R. Tate, Herr A. Bittner, and myself. These add considerably to our knowledge of the fauna; they show that it is Eocene and Oligocene, instead of Miocene, and that it is remarkably varied and rich in genera. I am now able to add one or two more species to the list, and at the same time take the opportunity of referring to one or two changes proposed by Prof. Tate and Herr Bittner.
