the Ulmaceoe to which it could he referred. As, however, it does not belong 
to any living genus, I consider it better to class it in an extinct one.

Ohs. — A fossil leaf which is indicated by all its characters as a Ficus. 
The substance must be considered firm, rather coriaceous than membranaceous. 
The lamina, being rather broad, is narrowed at the base into a strong petiole, 
from which runs up a strong and straight primary nerve. The secondary 
nerves are pretty strong, 13 millimeters distant from one another, and curving 
upwards to the margin anastomose in following the borders. The tertiary 
nerves are 2-3 millimeters distant from one another, and diverge from the 
primary one at right angles, and from the outer side of the secondary ones at 
acute angles, thus running in an almost transverse direction. They enclose 
a network consisting of lax meshes. 
The leaf reminds us of that of Ficus lanceolata, Ilcer, from which it 
differs only by a less narrowed base and by the tertiary nerves running in 
another direction. 
Locality and Horizon. — Between Hill and Watson’s shafts, in white 
pipeclay, from the Old Bose Valley Lead, on the Main Vegetable Creek 
Lead, Emmaville (Vegetable Creek Township).
