32 A. Liversidge—Torbanite of New South Wales. 
The material now available for a restoration of 7%noceras 
grande Marsh, is sufficient to show that this animal was similar 
in general proportions to Dinoceras mirabile, but of muc 
larger size. e few specimens that can at present be 
referred to Uintatherium leave many points in its structure 
undecided. The type specimen of this genus is from a lower 
horizon than that of either Dinoceras or Tinoceras ; the 
evidence now at hand seems to indicate that Uintatherium is 
the oldest and most generalized form of the Dinocerata. 
specimen in the Yale Museum from near the original locality, 
and agreeing, so far as the comparison can be made, with the 
type, as four lower premolars. This character will serve to 
istinguish Uintathervum from Dinoceras, to which it has various 
points of resemblance. Tvnoceras is from a horizon higher than 
Dinoceras, and is much the most specialized genus of the group.
