THE FOSSIL FEUNS.

Anomopteris, from a privative, vop.os, a law, and 

 a fern. 



Leaves pinnated ; leaflets linear, entire, somewhat plaited 

 transversely at the veins, having a mid-rib ; veins simple, 

 perpendicular, curved. Fructification arising from the veins, 

 uncertain as to form ; perhaps dot-like, and inserted in the 

 middle of the veins ; or perhaps linear, attached to the 

 whole of a vein, naked as in meniscia, or covered by an 

 indusium, opening inwardly. 



One species in the new red sandstone. 



TcBfyiopteris, from rcuwa, a fillet, or wreath, and nrfpis, a fern. 



Leaves simple, entire, with a stiff, thick mid-rib ; veins 

 perpendicular, simple, or forked, at the base. Fructification 

 dot-like. 



Three species in the lias and oolite formations. 



We add a figure of T. vittata (fig. 121), together with a 

 magnified leaflet, from Lindley and Hutton, PL 62.
