bears a minute spinula on the apex of their leaves, which are obtuse, and 
show a recurved margin. As the apex of the fossil leaf is not perfectly pre- 
served, it cannot he decided whether a spinula was present or not ; and as the 
under surface of the fossil is not visible, it is impossible to ascertain whether 
the margin is recurved, though the latter is probable, as well as that the 
under surface was covered with a felt. Pig. 13a represents a part of the leaf 
slightly enlarged.

Ohs . — Pragments of pinnatisect and coriaceous leaves which according 
to their characters can scarcely be placed in any other order than the Pro- 
teaceoe. Pig. 12 represents only the upper part of the leaf with the apex. 
The presumed form of the lamina was oblong ; the lateral segments are 
oblong, rounded obtuse, somewhat narrowed at base, rapidly smaller towards 
the apex ; the terminal segment is small lobed at base, rather narrowed at 
apex, and there almost roundly obtuse. The borders of the segments are 
obtusely toothed. The teeth appear now and then somewhat thickened on 
their ends (see Pig. 12a, representing a segment enlarged), and it seems that 
they hear a spinula which is probably recurved towards the under surface. 
Accordingly, only the base of the spinula can he visible, and the before- 
mentioned thickenings may correspond to it. Of the nervation only the 
upper part of the primary nerve is to be seen which is straight and attenuated 
here, hut probably strong in its other parts. The secondary nerves diverge 
from it at pretty acute angles, distant about one centimeter from one another, 
and run towards the borders. Tertiary nerves and network are slightly 
developed, the latter is only indistinctly perceptible. The comparison with 
the corresponding types of the living Proteaceae led me to the species of 
Grevillea with pinnatisect leaves. Only when more completely preserved
