A younger frond than 39,201 (Fig. 1, PI. I.), showing the 

 overlapping of the pinnae, which have the eared base and obtusely 

 pointed tips, as in the larger example.

Frond narrow, linear ; pinnae short and broad, attached to the 

 upper face of the rachis by a broad base, of which the upper 

 corner is slightly auriculate ; the apex is bluntly rounded, the 

 tip being directed upwards. Venation of the Otozamites type. 



In the Museums of York and Leeds there are a few fairly 

 large and well-preserved fronds which I regard as specifically 

 identical with certain Italian specimens named by Zigno Otozamites 

 Feistmanteli; they are characterized by their long and narrow form, 

 comparable to 0. Bunburyanus, and short and broad pinnae. The' 

 pinnae differ from those of the latter species in being longer and 

 less orbicular in shape; but some fronds referred by Zigno to 

 Otozamites Trevisani 1 furnish an example of a form more or less 

 intermediate between 0. Feistmanteli and 0. Bunburyanus. It 

 is not improbable that another Italian frond named by Zigna
