ResumoProfessor Eduard Suess, F.M.G.S., recently received from Comén, near Trieste, a specimen showing the hinder half of the skeleton of a lizard which he has desired me to describe. Unlike the two fine-slabs from the island of Lesina, preserved in the k.-k. geologische Reichsanstalt, which are in a pale yellowish limestone matrix, this specimen is from a limestone slab nearly black; the animal shown upon it has lain exposed for some time in the quarry and suffered by the solvent action of the rain. Prof. Suess mentioned to me that the colour merely indicated one of the many alterations in the limestone, and that, since it was collected by a former pupil, no doubt could attach either to its stratigraphical or geographical position. Prof. Kornhuber does not appear to have been quite certain as to the position of the Lesina rocks in the Cretaceous series ; but while I was in Vienna, Professor Pisani mentioned to me that he had identified thirteen species of fish with Upper Neocomian species ; and as fish constitute the chief fossils of the deposit, this must be held conclusive evidence of the geological age of these lizards. This new fossil (P1. IV. fig. 1) at first sight presents a considerable resemblance to the Hydrosaurus lesinensis of Kornhuber, as was pointed out to me by :Prof. Sucss; but the differences are so remarkable and important that I find myself unable to include it. in the same genus. The specimens in the Museum of the Imperial
