Obs. Diprotodon combines the characters of the genera J\Iacropus and 
Pliascolomys, but with special modifications of its own, more paiticularly exhibited in 
the bones of the trunk and limbs. The pelvis and femora present resemblances to the 
Proboscidso not hitherto observed in any other remains of large extinct quadrupeds in 
Australia. lu all the bone.s, however, essentially marsupial characters are visible.

Sir llichai’d Owen has recorded twentj-one occasions on which the remains o£ 
this large mar.mpial have been found throughout Australia f ; of these discoveries no 
less than thirteen refer to Queensland, viz. : — 
1. Tributaries of the Oondamine Kiver in a deep bed of alluvium ; Sir T. L, 
Mitchell, 1842. 
2. Hodgson, Campbell, Isaac, and Oaky creeks, Condamine River, either in 
red loamy breccia, or a bed of pebbles ; L. Leichhardt, 1844. 
3. King’s Creek, Darling Downs j — Turner, 1847. 
4. Isaac’s Creek, Cowrie, Darling Downs ; If. N. Isaacs, 1849. 
5. Galtindaddai, Melville Plains ; Jp^. Buchanan, 1851. 
6. Creeks, Darling Downs; H. ILugles, 1856. 
7. Cowrie, Darling Downs; J. E. Allporf, 1869. 
8. Condamine Valley, 100 feet below surface; J. H. Hood, 1861. 
9. Eton Vale, Darling Downs ; E. S. Rill, 1863. 
10. St. Ruth’s Station, Condamine River; H. Campbell, 1865. 
11. St. Jean Station, Condamine River ; S. St. Jean, 1865. 
12. Clifton Plains, Darling Downs ; F. Nicholson, 1866. 
13. King’s Creek, Clifton Station, Darling Downs; O. E. Bennett, 1877 (about). 
This list of localities does not appear to include that of the original skull sent to 
London by Mr. Royd and purchased for the British Museum. It was from the “ bed of 
a creek at Cowrie, near Drayton, Darling Downs,” and is probably identical, says Sir 
R. Owen, with the head referred to by Dr. G. Bennett as found by a shepherd on King’s 
Creek. 
To the above must be added the discovery of Diprotodon remains in brecciated 
alluvium by the late Mr. R. Daintroe, on Maryvale Creek, Clarke River.J 
Loc. and Horizon. As given above— Pluviatile deposits.
