Ohs. — Notwithstanding that this fossil leaf shows no more than a 
peculiar irregularly dentate margin, and a prominent straight midrib, together 
with an oblong form and a coriaceous texture, I will, considering the small 
number of fossil plants which have as yet been brought to light from the 
Tertiary of Australia, endeavour, instead of putting it aside, to determine 
the same. At the first glance, the genus Knightia occurred to my mind, and, 
in fact, I am able to assign several reasons why the specimen should he 
referred to that genus, which at present is indigenous to New Zealand. Our 
fossil appears to correspond to a variety of the Knightia excelsa , 11. Brown, with 
oblong leaves (compare Ettingshausen, Blattskelete der Apetalen, PI. NLIII, 
figs. 2, 8). The unequal obtuse teeth of the margin correspond exactly to 
those of the leaf quoted, Eig. 2. In Knightia the consistence of the leaf is 
very thick, the secondary and tertiary veins proportionately fine, and the 
meshes of the net very narrow and delicate, so that the non-preservation of 
these veins in the fossil Knightia would he easily explained.
