ADDITIONAL COLLECTION FROM STRATUM NO. 4 OF THE SECTION. 
After the completion of the foregoing paper, which considered 
only the fauna from strata Nos. 3 and 4 of the section at the city 
marl pit at DeLand made by Dr. E. H. Sellards and included in this 
report, the writer received from the Florida Geol. Survey a consign- 
ment of fossils collected by Mr. H. Gfonter from stratum No. 4 of 
this same marl pit. 
According to Dr. Sellards, the shell marl No. 3 of his section 
has an extremely irregular top surface, and the most pronounced 
break in the section is that between this marl and the overlying 
sandy clay (stratum No. 4.) 
The fossil collection from stratum No. 4 is represented by only 
one species, Ostrea virginica Gmelin. From this one species, it is 
hardly possible to assign the age, but as Ostrea sculpturata Conrad 
is plentifully represented in the underlying fossiliferous stratum, it 
appears highly probable that this oyster bed should be assigned to 
the Pleistocene.
