AN ACCOUNT OF GANOID FISH FROM  

QUEENSLAND Ceratodus ).  

By DR. ALBERT GUNTHER, F.R.S.  

Assistant Keeper in the Zoological Department of the  

British Museum.  

[PLATE LXXXVI.]  

257  

The genus Ceratodus lias been established by Professor Agassiz  

for teeth which are found in strata of Jurassic and Triassic forma-  

tions in various parts of Europe and India. These teeth (fig. 3),  

of which there is great variety with regard to general shape  

and size,* are much longer than broad—sometimes in. long—  

depressed, with flat or slightly undulated, always punctuated  

crown, with one margin convex, and with from three to seven  

prongs projecting on the opposite margin. They have always  

been found isolated, sometimes with portion of bony base  

attached to them. Yet Professor Agassiz pointed out, from  

their shape, that there must have been only two of them in the  

upper jaw and the same number in the lower, that the convex  

margin was directed inwards, and the prongs outwards. No  

other part of the fish to which they belong has hitherto been  

found associated with them; but Agassiz considered it to have  

been cartilaginous fish, or more especially shark—a view  

not so very far from the truth, as we shall see hereafter.  

The discovery of Ceratodont fish in the recent fauna is  

due to the Hon. William Forster and Mr. Gferrard Krefft, the  

Curator of the Australian Museum at Sydney. Years ago the  

former of these gentlemen had informed Mr. Krefft that there  

existed in the fresh waters of Queensland large fish with  

cartilaginous backbone, but he was thought to be mistaken  

Mr. Higgins possesses the largest, and probably most unique, collection  

of Ceratodont teeth from one locality—viz. from Aust-passage near Bristol.  

Among some 300 specimens there are scarcely two which are sufficiently  

alike to be assigned to the same individual.
