1795 
Up to this point these references are based upon published 
statements, which have been so conveniently summarised by Mr. 
Etheridge. We may now add to the list by a notice of some 
other discoveries in South Australia, which have either not yet 
been made public or which have only received a passing notice 
in the current press. 
In 1879 the South Australian Museum received, from Mr. R. 
M. Robertson various collections of fossil bones found near Nor- 
manville, South Australia. Amongst these, which included 
remains of Diprotodon, Macropus, Phascolomys, Bettongia and 
Thylacoleo, were a portion of a femur and of two or three tibie. 
We are now able to refer all the latter to the Callabonna bird. 
In 1889 one of us (A.Z.), in the course of the exhumation of 
Diprotodon bones at Baldina Creek, on the edge of the Eastern 
Plains, near Burra, South Australia, obtained a considerable 
portion of a femur, which can also be referred to the same species. 
Lastly, in 1893, came the discovery, already noticed in 
‘‘Nature,”* of a large number of bird-bones at Lake Callabonna 
found in association with those of Diprotodon and of other extinct 
marsupials. To the circumstances of this discovery, so far as it 
relates to the birds, a few further details will be given directly. 
For convenience of reference we may now epitomise, in their 
proper order, the various discoveries of large bird bones which 
have been mentioned above.
