PRELIMINARY NOTES ON CINCINNATIAN AND 
LEXINGTON FOSSILS/ 
Aug. F. Foerste. 
The Saluda bed is typically exposed at Madison, Indiana, but 
the name was taken from Saluda creek, eight miles southwest of 
Madison, because the latter name was preoccupied. At Madison 
it consists chiefly of argillaceous limestones forming massive beds, 
but near the base the rock weathers to thinner layers which north- 
ward, in Jefferson and Ripley counties, become more conspicuous 
and have there, on account of their thin bedding, been called 
shales. Very fine, microscopic grains of sand are present, which 
become more abundant southwards, so that in west-central 
Kentucky the rocks feel gritty between the fingers. The name 
Saluda was introduced chiefly on lithological grounds, to dis- 
tinguish the comparatively unfossiliferous fine-grained, argilla- 
ceous limestones, forming massive beds at numerous ffills, from 
the underlying thin, blue limestones, interbedded with consider- 
able clay, both richly fossiliferous. As a matter of fact, the 
Saluda of Indiana and northern Kentucky contains a consider- 
able variety of species, but usually the individual specimens are 
few, or the specimens do not weather out well and very little 
effort has been made to collect them excepting at two horizons: 
at the top, in the Hitz layer, and at the base, immediately above 
the chief Columnaria layer. An effort Was made to introduce a 
paleontological base for the Saluda bed, and the chief Columnaria 
layer, and, in its absence, the massive Tetradium layer, was chosen 
for this purpose. Unfortunately, these coral layers cannot be 
traced south of Hanover, Indiana, and beyond this locality, only 
the lithological distinctions can be utilized. 
Recently Prof. E. R. Cumings has traced the Saluda northward 
in Indiana and has shown that it wedges in between the Liberty 
and Whitewater beds. In Ohio, I have seen the strata thus iden-
