which the Waynesville invasion formerly had progressed south- 
ward. 
The Waynesville and Liberty, taken together, contain that 
part of the Eichmond fauna along the Cincinnati geanticline which 
most nearly is related to the Mississippi Valley Eichmond. The 
two formations appear more closely linked together in their fossil 
content than the other Eichmond formations. For that reason 
the term Laughery formation is proposed for the Waynesville 
and Liberty as exposed along Laughery Creek in Eipley county, 
Indiana. 
On the eastern side of the Cincinnati geanticline, the Blanches- 
ter division of the Waynesville bed may be traced by means 
of typical fossils as far as Owingsville, in Bath county, and the 
base of the Liberty is fossiliferous as far as the same locality. 
Here again it is the strata along the plane of junction between 
the Waynesville and Liberty wMch may be traced farthest south- 
ward. 
The great coral horizon at the top of the Waynesville or at 
the base of the Liberty may be traced from the western side of 
the Cincinnati geanticline eastward as far as Ophelia, 4 miles 
north of Eichmond, in Madison county, and as far as the mouth 
of the Eed Eiver at the northeastern edge of this county. Here 
it may be seen that the overlying strata are unfossiliferous south- 
ward, but gradually become more and more fossiliferous north- 
ward, simulating in this respect the features shown by the Saluda 
on the western side of the geanticline. 
Owing to the considerable lithological and accompanying faunal 
differences between the Cincinnatian strata as exposed in Ohio 
and Indiana, and their approximate stratigraphical equivalents 
in central Kentucky, it may prove convenient, locally, to recog- 
nize only the greater subdivisions of the Cincinnatian strata, as 
proposed at the typical section, at Cincinnati, Ohio, and to adopt 
a somewhat different set of subdivisions southward. 
The terms employed on the following pages are indicated in 
the following table.
