148 
recurved. The nervation shows a comparatively strong primary nerve, being 
straight and prominent at apex, and almost regular secondary ones which run 
rather straight near the margin. It seems that they anastomose here by 
loops, yet the latter arc scarcely discernible. 
Apocynophyllum parr folium, Ett., of the Eossil Elora of Haering 
possesses similar leaves. In addition, A. stenophyllum, Eng., A. elongatum, 
f leer, and A. attenuatum, Heer, arc worthy of remark, as being analogous to 
the fossil in the European Tertiary Elora. But our fossil is different from all 
the species named by the thick substance of its leaf and the obtuse ends of 
its lamina. 
Locality and Horizon. — Witherden’s Tunnel, Two-mile, on Vegetable 
Creek, Main Deep Lead ; brown carbonaceous clay, below basalt. 
Genus APOCYNOCABPUM. 
Gen. Char. — Eolliculis compressis, anguste lanccolatis, utrinque 
acuminatis. 
Apocynocarpum sulcatum, sp. nor. 
Plate XIII, Fig. 11. 
Sp. Char. — A. folliculis lineari-lanceolatis, longitudinaliter sulcatis, 
leviter curvatis. 
Ohs. — Eolliculous, resembling the fruits of Apocynum, Nerium, and 
other Apocynese. Our fossil fruit is linear-lanceolate, compressed, and striated 
in its length by three narrow furrows. Another specimen of a fruit is to be 
seen associated with it on the same matrix, which seems to appertain to a larger 
specimen of the same species. But the latter is less well-preserved than the 
former, and, therefore, not figured here. 
Locality and Horizon. — Witherden’s Tunnel, with the preceding 
species. 
A SPHRIFOLIAE. 
Trachyphyllum myosotinum, sp. nor. 
Plate XIII, Figs. 19, 19a. 
Sp. Char. — T. foliis conferte tubcrculatis, breviter petiolatis, anguste 
lanccolatis utrinque acuminatis, integerrimis ; nervatione brocliidodroma ;
