appears to be flattened from side to side. The proximal 

 articulation appears to be at right angles to that of the 

 distal end. 



No tarsal bones are preserved. 



The Metatarsus o/ Palaeosaurus. 



The metatarsus is represented by several bones. No. 79 

 is a left metatarsal 4^ inches long, ^^ inch wide at the distal 

 extremity, and ^ inch wide above the distal articulation. Its 

 proximal end is stout, fully an inch wide, oblique to the 

 distal end, and inclined outward. 



The type specimen is 8^ inches long, -i^jj inch wide at the 

 distal end, j*^ inch wide in the lower third, and lyV inch 

 wide at the proximal end, which, as usual, is concave on the 

 under surface and oblique. No. 83 is a little smaller, the 

 metatarsal being 3 inches long, with tiie proximal end jV inch 

 wide and -j^j inch deep. These measurements arc such that the 

 bones might all belong to one foot, and they are provisionally 

 referred to Paleeosaurus.
