Locality : ïymovskaya Padj near Niklewicz's coal mine. 



Leaf small, 2 cm. in length and 1.5 cm. in 

 width, broadly ovate or nearly orbicular, margin 

 serrate, more distinctly towards the top. From a 

 point of the base arise the shghtly prominent

 Patoot Beds,^^ and il/. appencUculata Hr. in the Atane.'^ The 

 leaves of both have a quite entire margin, and the latter has 

 besides auriculate appendices at the base. Our leaves are, 

 however, dentate on the upper two tlairds of the margin. 

 A more close affinity with our fossil is shown by some Arctic 

 species, treated by Heee as Tertiary. These are M. Lijellii He.'^ 

 with narrow lanceolate leaves and M. dentata He."^ with broader 

 leaves ; from both of which our species differs by an evidently 

 smaller size and a more circular outline, thus separating ours as a
