Of the Ashley fossil shells, Nautilus Alabamensis, Scalaria amplicosta, and Conus gyratus 
alonea, re common to the Ashley and Santee beds. Gryphea mutabilis, Anomia jugosa, the spe- 
cies of Scalaria, and the Balani, retain their calcareous coverings—the rest are all in the state of 
casts, but so perfect are those of the bivalves, in the upper marl stone, that impressions taken, in 
plaster, from the external casts, by my friend, Mr. Holmes, were almost as characteristic as the 
original shells. 
Venus crassus bears so strong a resemblance to the Miocene species, V. Lyrata, Con. that it was 
not without hesitation that I separated them. Cardita dubia can scarcely be distinguished from a 
species found in the Miocene of Pamunkey, Va. V. proxima is like V. cortinaria; in a word, any 
one acquainted with our fossils would be struck with the Miocene aspect of these; and had I not 
found them associated with Gryphea mutabilis, Pecten calvatus, Conus gyratus and Panopea 
elongata, | would not have ventured to place them here. 
Between the Gasteropoda and the Lamellibranchiata, numerically, there is not much difference ; 
but the existence of the remains of terrestrial mammalia shows that the Ashley beds were depo- 
sited at no great distance from land. 
Some of the fossils of the S. Carolina Eocene have a wide range. Those found in the contem- 
poraneous beds of Maryland are the following. 
Turretella Mortoni, Crassatella aleeformis, 
Bs humerosa, Ostrea compressirostra, 
Cardita planicosta, Panopea elongata. 
“ Blandingi, 
And the following are found in the Eocene of Virginia. 
Infundibulum trochiformis, , | Cardium Nicolleti,* 
* This fossil was brought from Missouri by the lamented Nicollet. I next found it in the Eocene of the Pamunkey, Va. and 
again in South Carolina.
