But as the Permian fauna did not show a close relation to the 
eastern fauna, so also there are no relations between the East Indian 
Triassic fauna and that of New Caledonia, New Zealand, and 
Japan, where the Monotis seems to be mepresénted by the genus 
Pseudomonotis. 
That this remarkable connection of the East-Indian archi- 
pelago with Europe by the intervention of the Himalaya still 
continued during the Jurassic period is proved by the discovery 
of Liassic and Oölitic fossils on the island of Rotti, —as, for exam- 
ple, Arietites geometricus, Harpoceras cf. Eserii, and Belemnites 
gerardii. i 
It is probable that only after the Jurassic period the East- 
Indian archipelago came out of direct connection with the Euro- 
pean sea, and remained so until now.
