Normanville and Baldina Creek, 8.A., are also to be attributed 
to the same bird, but it should be stated that, though corre- 
sponding with the Callabonna femora in all anatomical details 
which are available for comparison, the former fragments are 
parts of bones of distinctly less size than the smallest of the 
latter, as shown by the fact that their circumference, at the part 
corresponding to the mid point of the entire bone, is nearly an 
inch and a half less. In the portion from Baldina Creek, 
however, enough of the bone exists to permit of a comparison 
in many details, and in these as stated, no essential differences 
can be detected.

For convenience of reference the measurements are given both in inches 
and millimetres. 
The asterisk indicates that the measurements so marked are 
slightly curtailed by reason of abrasion of the bones. 
Nos. 1 and 2 of Genyornis represent a pair of bones—the 
largest in the collection. . 
The measurements of D. maximus and D. elephantopus, 
are from Professor Owen’s Table of Measurements, Trans. Zool. 
Soc., vol. VIII., p. 371; those of pyornis from Oiseaux des 
Iles Mascareignes A. Milne Edwards, p. 96; and those of 
Dromornis partly from Owen’s description, Extinct Wingless 
Birds of New Zealand, Appendix p. 2, and partly from a cast. 
Tibio-tarsus.—Of these bones two only, viz., those belonging 
to the large pair of femora, Nos. 1 and 2 of Table I, are undis-
