30 CRETACEOUS GROUP 



of Alabama. They approach very nearly, he conceives, 

 to some large vertebral bones from Honfleur, figured by 

 Cuvier, (Ossemens Fosnles.) See Journ. of Acad, of 

 Nat. Sc. vol. vii. 



In the Academy of Natural Sciences, and in private 

 collections in this city, are some interesting remains 

 which appear to have belonged to Saurian animals. I pos- 

 sess some singular specimens figured on pi. xviii., figs. 1 

 and 2. At first I supposed them to be dermal bones, allied 

 to those of the Hylseosaurus^ as figured by Mr. Mantell $ 

 but as they possess a distinct enamel, and as some speci- 

 mens are worn by attrition on the apex, they may have 

 been the palate bones of some marine animal. 



Testudo. 



There are, in the Academy of Natural Sciences, seve- 

 ral bones which appear to belong to a large species of 

 Testudo. 



PISCES. 

 Squalus. 



Bones and teeth of various species of shark are abun- 

 dant in this formation. They are mostly in fine preser- 

 vation ; and I am indebted to my friend J. P. Wetherill, 

 Esq. for the use of several beautiful specimens in his pos- 

 session. Notwithstanding the admirable perfection of 

 these remains, I am not sufficiently acquainted with 

 them, (excepting perhaps in two or three instances) to 

 identify them with known species, either recent or fossil.
