NOTOTHERIUM. 
(Plate vi., Figs. 8, g, 10) 
The genus Nototherium was established by Prof. Owen in 1845, 
and comprises animals which are somewhat less in size than the 
better known genus Diprotodon. 
The animal closely resembled its larger companion, but also 
had many points in common with the Wombat (Phascolomys). In 
referring to the limb bones and skeleton, Lydekker“ states : “The 
limbs are of equal length ; the humerus has an entepicoudylar 
foramen, and closely resembles that of Phascolomys ; the olecranon 
is well developed, and the other limb bones and vertebrae are of the 
type of those of the latter genus. The structure of the feet is not 
fully known, but it apparently approximated to that of Phascolomys. 
This family (the N ototheriidce) connects the Phascolomyidw with 
the Diprotodontidce ; the cranium, limb bones, and vertebrae being
