Some account of the discovery of fossil remains at Lake 
Callabonna, by one of us, appeared in “ Nature,” 1894, Vol. L., 
pp. 184 and 206. Since then various circumstances which were 
alluded to at the time, besides considerabie difficulties in connection 
with the restoration and treatment of the bones have retarded the 
development of the discovery and the publication of the results ; 
nevertheless, though the work of dealing with a large mass of 
material is still far from complete, we find ourselves, at last, in a 
position to offer to this Society some preliminary notes upon the 
subject in respect of the remains of the large struthious bird 
which were found in association with bones of Diprotodon and 
other extinct marsupials. 
As, in the course of this paper, reference will have frequently 
to be made to previous discoveries, in Australia, of bones of the 
same group of birds it will be convenient to commence our 
observations by a brief epitome of these. 
That work has been materially facilitated by a paper by Mr. 
Robt. Etheridge, junr., who, in a paper in the “ Records of the 
Geological Society of New South Wales,” + succinetiy reviews the 
history of the various discoveries of struthious birds in Australia. 
From this paper we have freely borrowed, and we accordingly 
express our thanks and acknowledgment. 
* Justice requires an acknowledgment on my part that to Mr. Zietz 
belongs the credit not only of having conducted the exhumations at Lake 
Callabonna, under arduous circumstances, but also of having most success- 
fully carried out the tedious work of the restoration of bones which 
presented peculiar difficulties in treatment. I must be the first to admit 
that collaboration on my part has only been made possible by the patient 
and laborious exercise of Mr. Zietz’s skill in this direction.—[E. C. S.]
