PRELIMINARY NOTES ON CINCINNATIAN FOSSILS. 
Aug. F. Foerste. 
The attempt to identify all the fossils found in Cincinnatian 
areas with the forms already described by various American and 
European writers has the disadvantage that it fails to account for 
the numerous varieties which may be distinguished when forms 
from different faunal provinces and from different horizons are 
subjected to more exact study. For purposes of stratigraphical 
studies the recognition of these varieties often is of the greatest 
value. In the following notes attention is called to a number of 
these varieties. Some of these appear to be sufficiently distinct 
to warrant their designation as species. 
The following table, indicating the classification of the Cincin- 
natian strata in Ohio, now in use, will be of service in determining 
the vertical distribution of these fossils:
