3. LIST OF LOCALITIES. 
For the convenience of students and collectors a list is here 
given of exposures in the city of Cincinnati, and immediate 
vicinity, where the various beds may be studied and their 
fossils collected. The list is not exhaustive. Other expos- 
ures of greater or less extent may be found. Grading and 
other improvements are continually affording new exposures, 
but from becoming overgrown and other causes, dumps, and 
even cuts are in a few years spoiled for geological purposes. 
All the strata have been exposed at one time or another, but 
not all are now exposed. The list given must be regarded, 
at best, as but temporary. On the map (Plate I), the location 
of these exposures has been indicated, the abbreviations be- 
ing placed as nearly as possible upon the exact locations. 
The map is a partial reproduction of a part of the Cincin- 
nati sheet of the Topographic Map of the U. S. Geological 
Survey. 
TRENTON PERIOD. 
The principal exposures are on the south bank of the Ohio 
from West Covington to Ludlow; at the mouth of the Lick- 
ing River (Covington side); two outcrops on the west bank 
of the Licking River in Covington; several small streams 
flowing into the Licking south of Newport and Covington, 
cut into the Trenton as well as afford exposures of the lower 
Utica strata; débris from Trenton strata has been thrown 
out in excavating the new water-works tunnels; the south 
bank of the Ohio River in the vicinity of Fort Thomas shows 
the Trenton outcropping; several quarries, now abandoned, 
on the road between New Richmond and Point Pleasant, in 
Clermont County, Ohio, have been opened in Trenton strata.

UTICA GROUP. 
Lower Utica.—The lowest strata of the Utica may bé found 
in the north bank of the Ohio in the First Ward (Fulton), 
and in the south bank of the Ohio overlying the Trenton
