in the size of the fore and hind feet is such as we find in some exist- 

 ing Terrapenes, e.g. the Emys geographica. 



The more obvious inferences are the same which are deducible 

 from other foot-prints in sandstone, viz. that the animal which 

 made them was walking in air. In the present instance it is plain 

 that they were not left by an amphibious fish, such as the sand-hopping 

 Lophiidce, but by a veritable air-breather ; and they must have been 

 made under those circumstances so well explained by Sir Charles 

 Lyell, in his paper on Recent and Fossil Rain-prints {vide supra), as 

 being essential to their preservation, viz. on an extent of sandy shore 

 lying between high and low water mark. 



Amongst the air-breathing classes of Vertebrata, the shortness of 

 the steps and the median track of the impressions in question point 

 plainly to the Beptilia ; and here, from the breadth and shortness of 

 the body, our choice lies between the Batrachia and Chelonia ; and, 

 on the grounds assigned in the above description of the tracks, I in- 

 cline to refer them to a species of Terrapene or Emydian Tortoise.
