Tertiary. PALMONTOLOGY OF VICTORIA. (Mammalia. 
I am here enabled to figure one of the simple conical arched 
anterior teeth of this curious carnivorous extinct genus of Whales, 
so unlike the lobed posterior molars figured in our second Decade, 
but showing in this another approximation to the larger extinct 
Cetacean genus of Tertiary Whales, the Zeuglodonts of America. 
This is one of the many interesting discoveries of Mr. W. Nelson in 
the Waurn Ponds quarries of the Miocene Tertiary deposits near 
Geelong, from which place also I should mention that the Rey. 
Mr. Price has sent me a portion of the lobed posterior tooth, like 
that in our first figures from a different locality. 
EXPLANATION OF FIGURES. 
Plate LV.—Fig. 3, side view of fang and crown, natural size, Fig. 3a, surface of crown, 
magnified to show the character of the ridging, agreeing with that of the lobed teeth. Fig. 3b, 
form of section of base of crown.
