 plete at both ends, is 21 mm. long and at the deepest part measnres 

 3 mm. in width. 



A portion of the upper mandible of an animal doubtfully rep- 

 tilian is shown in pi. 11, fig. 3. The dentigerous border is thickly 

 studded with minute, sharply pointed teeth. The preserved frag- 

 ment measures 13 mm. in length.

 fail to find remains sufficiently characteristic to verify their presence. 



A large number of fish vertebra' were found intermingled with the 

 other specimens, but were too fragmentary to admit of identification.
