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 pl. xviii., figs. 1 
and 2. At first I supposed them to be dermal bones, allied 
to those of the Hylosaurus, as figured by Mr: Mantell 3 
but as they possess a distinct enamel, end 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.
