The Uavbouitorsus species amount to about 40, of which perhaps 
30 are sufficiently complete to be satisfactorily identified. Of 
these, nearly all the most distinctly marked are identical with 
European Gai tenatacons species or are very closely allied to 
them; such as Calamites gigus, Annularia longifolia, Neuropteris

the strata which weaugy them; of this, however, there may be a 
qu rie since forms identical with, or allied to, many of those 
described have oi obtained from the Rhetic beds in other

as the base of the Jurassic system, and not Triassic—a view whic 
is gaining ground in Europe—there can be no objection made to 
this conclusion.
