The species, which seems to be distinct from known forms, may be named 

 Testudo crassiscutata. 



14. Two vertebrae of a large serpent, undetermined. 



15. Several teeth, a fragment of the mandible, and several dermal plates 

 of a Crocodile, probably the Alligator mississippicnsis. A dermal plate has its 

 greater breadth 70 mm. and its shorter 53 mm. Its boss is elliptical and 

 thick, 43 mm. by 15 mm. and 27 mm. high. A smaller plate, represented 

 in fig. 2, plate IV., is 50 by 45 mm. in breadth, and has its boss 40 by 20 

 mm. broad and is 24 mm. high. 



16. Associated with the foregoing are a few remains of fishes consisting 

 of several vertebrse of Sharks and Teleosts, the swollen interspinal bone of 

 Epliipptis gigas, several large caudal spines and dermal tubercles of rays and 

 teeth of Diodoji, Myliobates, Oxyrhina and Galeocerdo.
