Ohs. — This leaf reveals a remarkably rigid texture, and shows an oblong 
form obtuse at both ends, a prominent entire margin, and a camptodromic 
venation with proportionately very lino, branching, anastomosing secondary 
veins, proceeding from a very strong midrib at not very acute angles. The 
tertiary veins, which probably bad been very line, and merging into a very 
minute net, are not preserved in the impression. As the fossil, however, in 
regard to its characters, corresponds best with leaves of existing and fossil 
Laurinese, I believe it should be incorporated in that order. And because of 
its striking similarity with the European tertiary Lciurus Swoszowiciana, 
Ung., I refer it to Lciurus itself. In the North American Tertiary Elora, the 
L. socialis, Lesq., approaches the Australian species. The latter differs 
from both of the species named, partly in its larger, broader leaves, and 
partly in its finer, more obtuse-angled, secondary veins. A more detailed 
comparison with other fossil and living species of Lciurus would be of no 
use until more perfect fossils are procured.

Ohs . — This is a mere fragment of a leaf, it is true, but it is easily 
restored as a lanceolate leaf whose venation is brocliidodromic. The margin 
of the upper portion is remotely denticulate, but most probably entire towards 
the base. The texture appears to have been rather rigid, or almost coriaceous. 
This fossil compares best with the leaves of the Australian Lomatia loncjifolia, 
It. Brown (Ettingshausen, Blattskelete der Apetalen, PI. XLII, figs. 10-12; 
Blattskelete der Dicotyledonen, PI. NXII, fig. 8). The species mentioned has 
leaves which, as regards form, dentation, texture, and venation, are so similar 
to it that the identity of the species might be assumed. This is especially
