Fix this textThe genus Ceratodus lias been established by Professor Agassiz
Fix this textfor teeth which are found in strata of Jurassic and Triassic forma-
Fix this texttions in various parts of Europe and India. These teeth (fig. 3),
Fix this textof which there is a great variety with regard to general shape
Fix this textand size,* are much longer than broad—sometimes 2 in. long—
Fix this textdepressed, with a flat or slightly undulated, always punctuated
Fix this textcrown, with one margin convex, and with from three to seven
Fix this textprongs projecting on the opposite margin. They have always
Fix this textbeen found isolated, sometimes with a portion of a bony base
Fix this textattached to them. Yet Professor Agassiz pointed out, from
Fix this texttheir shape, that there must have been only two of them in the
Fix this textupper jaw and the same number in the lower, that the convex
Fix this textmargin was directed inwards, and the prongs outwards. No
Fix this textother part of the fish to which they belong has hitherto been
Fix this textfound associated with them; but Agassiz considered it to have
Fix this textbeen a cartilaginous fish, or more especially a shark—a view
Fix this textnot so very far from the truth, as we shall see hereafter.
Fix this textThe discovery of a Ceratodont fish in the recent fauna is
Fix this textdue to the Hon. William Forster and Mr. Gferrard Krefft, the
Fix this textCurator of the Australian Museum at Sydney. Years ago the
Fix this textformer of these gentlemen had informed Mr. Krefft that there
Fix this textexisted in the fresh waters of Queensland a large fish with
Fix this textcartilaginous backbone, but he was thought to be mistaken
Fix this text* Mr. Higgins possesses the largest, and probably most unique, collection
Fix this textof Ceratodont teeth from one locality—viz. from Aust-passage near Bristol.
Fix this textAmong some 300 specimens there are scarcely two which are sufficiently
Fix this textalike to be assigned to the same individual.
