Geologic Horizon :—Pliocene. 
About one-half mile south of De Leon Springs in Volusia County 
the following section was examined: 
White sand, Pleistocene or Recent .... 4 feet. 
Unconformity, yellowish brown sand and clay unassorted near the top 
but grading downward to well stratified clay, Pleistocene. 7 feet. 
Unconformity, yellow to white shell marl, Nashua marl. .. 6 feet. 
Total ..... 17 feet. 
At one point the clay extends downward into the Pliocene marl 
in a channel two feet across and four feet deep. 
The names of a few fossils obtained from DeLeon Springs are 
given by Dali 1 in his list of Florida Miocene species. 
Dali’s list contains: 
*■Crepidula aculeata Gmelin. Carditamera a rat a Conrad. 
Ostrea sculpturata Conrad. Mulinia congesta Conrad. 
It will be noticed that this list includes only four species and the 
first ( Crepidula aculeata, Gmelin) is marked by an asterisk (*) in 
Dali’s table to indicate that it is believed to survive to the recent fauna. 
Of the other three, one, Ostrea sculpturata , 2 is known from the Flor¬ 
ida Pliocene of the Caloosahatchee River, Alligator Creek and Shell 
Creek, while another, Car ditamer a arata, is known from the same 
beds and from an additional locality. Both of these species are also 
known from the Pliocene fauna of the “Waccamaw beds” of the Caro- 
linas. This leaves but one species, Mulinia congesta, of Dali’s list 
which is not known from the Florida Pliocene. A recent collection
