Tertiary. | PALAONTOLOGY OF VICTORIA. [ Vertebrata. 
This, which is the most gigantic of all fishes (the teeth indicating 
a length of 40 feet), is also one of the most characteristic of the 
Miocene Tertiary of Europe and Virginia. I am glad, therefore, to 
figure it as portion of the evidence in favor of my reference of the 
Victorian Tertiary deposits near Geelong to the Miocene period, 
as the specimens from them are perfectly identical with those from 
Malta and the Miocene Faluns of Dax on the most careful com- 
parison. 
It is easily distinguished from the C. angustidens (Ag.) by its 
greater size, and the wider, triangular, single cusp, the lateral cusps 
being wanting. It is usually less thick, with finer serration and 
proportionally smaller root ; the glossy ganoine of the surface is 
also thinner and less lustrous. 
Rare in the Miocene Tertiary of Bird Rock, near Geelong.
