PLESIOSAURUS. 



Of the Saurian reptiles, the remains of which abound in the 

 secondary strata in this conntry, the Plesiosaurus is unquestion- 

 ably one of the most interesting ; we are informed that several 

 skeletons of this extraordinary animal have' been taken up lately ; 

 one of them in so perfect a state as to enable Mr. Conybeare to 

 determine with a certain degree of precision the general form 

 and characters of the skeleton of the animal : we shall ouly now 

 mention the great length of its neck, in consequence of the extra- 

 ordinary number of cervical vertebrae, amounting, perhaps, to 

 forty, a number far exceeding any thing that has hitherto been 

 observed in any class of animals.
