now-—as regards at least the Gycadeacew —to a great extent removed. This break 
is still more filled in by the interesting circumstance (to be noticed presently) 
that there are other forms, both in the Lower and Upper Gondwanas, which find 
their close analogie.s or identical representatives in the Jura of the Altai and 
Siberia and elsewhere. 
Before proceeding to this point, the systematical position and analogies of 
Ndytjerathio^sis, Ustm., may be therefore expressed thus—

The Jurassic flora described by Professor Schmalhauscn from the Altai 
IVP*' and the Tunguska river,^ is further interesting, as it contains several forms 
partly identical with and partly closely related to species in the Upper and 
Lower Gondwanas of India, representing thus, so to speak, an amalgamation of 
parts of both. Taking also the other Jurassic floras of E. Siberia and the 
Amur countrie.s (Ueer) into consideration, we can establish the following list of 
correlations: —
