FRONTISPIECE, 



The photograph represents the nearly complete skeleton of Cruptocleidus oxoniensis 

 (R. 2860), as mounted in the Gallery of Fossil Reptiles. All the bones belong to 

 a single individual and, with the exception of two or three ribs and neural spines, no 

 restoration has been made on the side shown. The total length of the skeleton is 

 11 feet.
