It was noted the other day, in the telegrams from Mel- 
bourne, that a jaw of this animal had been found and sent to 
Professor McCoy to be examined and described ; but, in the 
papers up to date, nothing has been written to state its value to 
science. To decide the disputed points, it is required that an 
entire lower jaw, or entire half or ramus, should come to hand. 
About ten yards lower down the creek I found the complete foot 
of what Dr. Bennett and others pronounced to be that of 
Tkylacoles ; but in this matter Professor Owen would not agree, 
unless they were found in such positions so as to identify them 
with other remains of Thylcicoles. It will be very difficult indeed 
to find specimens as perfect as that, as I have had to walk miles, 
down even G-owrie Creek, and find only one specimen of a 
species. 
Specimens of Diprotodon Australis were also found. Mr. 
Krefffc, in a letter to the Sydney Morning Herald , thus describes 
the Diprotodon : — “ The Diprotodon was as bulky as the largest 
“ living elephant, but stood low on its legs, which bore much 
“ resemblance to those of the Droboscidean . The feet, however, 
“ were more like those of the Mylodon , a South American gigantic 
“ sloth and further on, in the same letter, he says: — “I 
“ believe that the animal stood not more than six feet high at 
“ the shoulder, and that the tribe probably lived on coarse 
“ herbage or leaves, felling the trees with their great tusks like 
“ the modern beavers.” 
On the subject of the connection of this extinct marsupial 
with JBradypodal giants, in part 3, Phil. Trans. Itoyal Society, 
Professor Owen thus writes: — “It is true that in the propor- 
“ tions of the limbs, especially in those of the tibia and its 
“ distinction from the fibula, as in some other particulars of the 
“ osteology of the Diprotodon , it resembles more the wombat than 
“ the kangaroo ; but the more weighty and essential corre- 
“ spondences are with the Macropodidee — the equipedal modifica- 
“ tions are adapted and necessitated by the bulk of the extinct 
“marsupial herbivores. The most elastic imagination could 
“ hardly stretch to the association of the disproportionate hind 
“ limbs of the kangaroo with a trunk equalling that of a 
“ rhinoceros, for, according to that pattern, Diprotodon must have 
“ towered to a height of thirty feet. The departure from the 
“ type of its diminutive modern allies is again interestingly 
“ analogous to that which occurs in the herbivorous Bruta. The 
“bulk and weight of body in Megatherium precluded the propor- 
“ tions of length and slenderness, with terminal prehensile in- 
“ struments in the limbs, by means of which its diminutive con- 
“ geners and contemporaries have been enabled to withdraw 
“ themselves from an unequal conflict in the safe shelter of lofty 
“ trees. In like manner, the weight and bulk of Diprotodon 
“ militated against its enjoying the privilege of the elongate,
