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 measurements of D. maximus, D. elephantopus, and 
Dromornis are from Professor Owen’s Table of Measurements, 
Trans. Zool. Soc., vol. VIII., p. 371. 
The Zibio-tarsws, which in point of size may be compared with 
that of Pachyornis elephantopus (vide Table IT.), is brought into 
line with the Dinornithide by the presence of a supra-condyloid 
extensor bridge, but this is in Genyornis, nearly median in 
position, instead of being near the inner border as in the former 
family. 
The statement previously made, which assigned the Mount 
Gambier and Paroo River tibias to Genyornis now requires some 
further explanation. For, in Professor Owen’s description of the 
former fossil,* he states that of the “ bridge there is no trace . 
and there is no evidence of fracture of the piers of such a
