This Saurian , so well known by the name of Monitor, 

 Maestricht animal &c, was once among the inhabitants of 

 the shores of the American continent, as is proved by 

 teeth and vertebrae found in Monmouth, Burlington and 

 Gloucester counties, in New Jersey, and at St. Georges 

 in Delaware. 



The tooth represented on the annexed plate, was first 

 described and figured by Dr. Harlan ; since which time 

 numerous others have been found. Mr. Mantel], to 

 whom I sent a cast of one of them, assures me that he can 

 perceive no difference between it and the teeth from 

 Maestricht ; and that in fact they are as much alike as if 

 they belonged to the same species.
