Obs. — Incompletely preserved leaves, yet presenting sufficient points 
for comparison. The lamina is broad, oblong, and narrowed into a pretty 
strong petiole. The margin is entire, not sharply prominent, hence the 
texture might have been less firm. The strong primary nerve sends out 
numerous secondary nerves at rather right angles of divergence. They are 
prominent, flexuous, ramose, approximate, and shortened towards the base 
of the leaf and joined to one another by thin loops. The tertiary nerves 
form a lax meshed net, the nervules of which are mostly wanting. 
Our fossil scarcely agrees better with any other order than it docs 
with the Apocynacese, in which very similar leaves are to be met with. In 
the meantime it might, like the following species, be classed in the collective 
genus Apocynophyllum , till more complete material shall render its closer 
determination possible. 
Locality and Horizon . — Withcrden’s Tunnel, Two-mile, on Vegetable 
Creek Main Deep Lead, near Emmavillc (Vegetable Creek Township) ; car- 
bonaceous clay, under basalt. 
Apocynofixyllttm Warbtjrtoni, sp. non. 
Plate XIII, Fig. 8. 
Sp. Char . — A. foliis subcoriaceis, oblongo-lanceolatis, basi acutis, 
apicem versus angustatis, marginc integerrimis ; nervatione camptodroma ; 
nervo primario prominente, recto nervis ; secundariis numerosis, subangulis 
70-80° egredientibus, subrectis simplicibus; nervis tertiariis vix conspicuis. 
Obs. — Relating to texture of the leaf, this fossil agrees with that of 
the preceding species, but its shape is narrower lanceolate. The secondary 
nerves diverge from a thinner primary one. They are more numerously 
developed, straighter, and barely joined together. The tertiary nerves appear 
to be sparingly developed, or they arc scarcely discernible. The fossil agrees 
well with a specimen of Apocynophyllum hearing ianum laying before me; at 
the same time it differs easily from A. travertinum by having more numerous 
and approximate secondary nerves, although the leaf resembles the latter in 
form. 
Locality and Jlorizon . — Watson’s Starlight Claim, Tinglia ; chocolate- 
brown carbonaceous clay from Deep Lead (stanniferous), under basalt.
