The material which forms the subject of the present communication was recently discovered at two different localities in New South Wales, and was received for investigation partly from Prof. Sir Edgeworth-David through Prof. A. C. Seward, F. R. S., partly from Mr. G. D. Osborne, Lecturer in Geology at the University of Sydney. The two localities are (1) near Mt. Tangorin, Hunter River District, (2) Lyndon, S. of Eccleston, Allyn River. The six specimens from the first locality were all foundin situ by Mr. G. D. Osborne, in a fresh-water conglomerate belonging to the Kuttung Series of rocks, at an horizon at least 2,000 feet above the base of the series. The single specimen from the second locality was found as a loose pebble, but although the exact horizon is unknown the fossil probably also belongs to the Kuttung Series.
