0,147 (5*8 inches) ; these being much smaller than those 

 of either of the three propodials described by Owen in the 

 'Rep. Brit. Assoc' for 1839, p. 83, under the name of 

 Plesiosaurus grandis. There is a rugosity on the ventral 

 surface below the head. This specimen not improbably

 bable that this specimen may belong to C. truncatus.
