The specimen figured by PhiUips (Geol. Oxford, Diag. xxx.

 is given also by Sternberg (Flor. Vorwelt, pi. xxxvii. fig. 2, 1823).

 Teeniopteris scitaminea fi-om the Stonesfield Slate is in the Oxford 

 Museum ; it represents the apical portion of a leaf with a strong 

 midrib giving off slightly oblique secondary veins. Sternberg's
