Ohs. — Corresponds in some degree to Ficus arcinervis, Ileer, the 
nervation especially, represented in Pig. 1(3a (magnified), is quite comparable 
to that of the leaves of the species just named from Sagor, Austria. The 
form, texture, and the qualities of the secondary nerves and of the network 
are in both species almost the same. Yet the tertiary nerves of our fossil 
leaf are more prominent, and their angles of divergence to the secondary ones 
are more acute than those of the abovenamed species.

Ohs . — Allied to Ficus Ftcusii, Ett., in regard to its texture, form, 
and some qualities of the secondary nerves, but differs from that species 
by a more tender network, and by the basilar secondary nerves being less 
developed. Our species differs from the preceding one by a shorter leaf, by 
more obtuse angles, under which the secondary nerves diverge, by the more 
rounded endings of their segments, and by a more developed network. 
Locality and Horizon . — Old Hose Valley Lead, with the preceding.
