tified at only one locality three miles north of Oxford, on the east 
side of Four Mile creek, along a branch coming in from the north- 
east. The characteristic Whitewater fauna is found a quarter 
of a mile up the branch. Undoubtedly, other localities will be 
found in the western part of this state, but no corresponding strata 
are known at present anywhere along the eastern line of outcrop, 
from Dayton, Ohio, to Concord, Kentucky, and southward. 
There are two Hehertella insculpta horizons in Ohio. Only 
the upper one of these horizons was known at the time the name 
Waynesville bed was introduced, and this upper Hehertella 
insculpta horizon was chosen as the base of the Liberty bed. In 
reality, there is a greater stratigraphic break immediately above 
the upper Hehertella insculpta horizon, so that the latter should 
form the top of the Waynesville bed. This upper Hehertella 
insculpta horizon maybe traced through Indiana as far southward 
as Madison. However, within the limits of Jefferson county, the 
number of specimens at this horizon rapidly becomes less and at 
Madison only careful search will result in locating the horizon. 
Recently, Mr. John F. Hammel and the writer located this horizon 
accurately along the Hanging rock road at Madison, 32 feet 
below the base of the chief Columnaria layer, agreeing essentially 
with my measurements 5 years ago. Dinorthis suhquadrata 
makes its first appearance about 4 feet farther up. 
The same species of corals which are found in southern Indi- 
ana at the base of the Saluda bed, 32 feet above the top of the 
Waynesville bed, occur in Kentucky, on the western side of the 
Cincinnati geanticline, from Jefferson county as far south as the 
central part of Casey county, but below the lowest horizon con- 
taining and various Liberty fossils. Since 
this fossiliferous horizon underlies the southern continuation of 
the Saluda bed it seems evident that the Kentuckian coral hori- 
zon here mentioned, which is found at a still lower level, belongs 
not at the base of the Saluda but at the base of the southern 
extension of the Liberty bed. 
At these coral horizons in Indiana and Ohio the number of 
specimens of corals often is so great that the name coral reef seems 
pertinent. For the coral horizon at the base of the Saluda bed 
the name Madison coral reef was introduced and for that at the 
base of the Liberty bed, the name Bardstown coral reef. 
Another coral reef of much less importance occurs in the lower
