another and a very striking point of resemblance to those 

 already mentioned; since this genus of Fishes, though pre- 

 eminently Triassic, nevertheless extended its range into the 

 Jurassic. Upon the whole, therefore, there is reason to con- 

 clude that Australia has undergone since the close of the 

 Jurassic period fewer changes and vicissitudes than any other 

 known region of the globe; and that this wonderful continent 

 has therefore succeeded in preserving a greater number of 

 the characteristic life-features of the Oolites than any other 

 country with which we are acquainted.
