Many of these species also occur in the Himalayas, although until 
the completion of Mojsisovics’ monograph on the Himalayan 
Upper Trias no exact comparison with that region is possible. 
The above list shows that in California, as in the Himalayan 
and the Mediterranean provinces, with the beginning of the 
Karnic stage of the Upper Trias there came in from some 
unknown region a swarm of T7vopitide. It is interesting to note 
that during this period the Salt Range fauna seems to have pre- 
served its Arctic character, and to have been cut off from the 
sea in which the faunas of the Mediterranean, the Himalayan and 
the Californian provinces lived.t- Again here we see an indica- 
tion of a great change in physical geography, that has left no 
other record than the incursion of an exotic fauna.
