fauna of Nelson, Washington, Marion, and Casey counties made 
its way as far eastward as Ophelia, 4 miles north of Richmond, in 
Madison county, Kentucky. 
Another great period of deposition of argillaceous strata occurred 
during the Waynesville. Here, again, unfossiliferous, argilla- 
ceous deposits characterize the lower part of the member, while 
a return of fossil faunas takes place during the deposition of the 
upper part. In Marion, Boyle, Casey, Lincoln, Garrard, Madi- 
son, and Clark counties, in central Kentucky, no fossils occur in 
the lower part of the Waynesville, unless a thin, richly fosilliferous 
strip, often less than 2 feet thick, at the very base of the forma- 
tion, be regarded as of Waynesville age. As the lower, unfossil- 
iferous part of the Waynesville is traced northward, on the western 
side of the Cincinnati geanticline, it first becomes moderately 
fossiliferous, as far as Oldham county. From this point north- 
ward the abundance of fossils and the number of species rapidly 
increases. Similar features are seen on the eastern side of the 
Cincinnati geanticline, where the fossils are only moderately 
numerous in the lower part of the Waynesville, in Montgomery 
and Bath counties, in Kentucky, but become abundant farther 
northward. 
The Fort Ancient and Clarksville divisions of the Waynesville 
can be traced only a short distance south of the Ohio River, on 
the eastern side of the geanticline. The Blanchester division, 
however, has been traced as far as Owingsville, in Bath county. 
On the western side of the Cincinnati geanticline, the Fort Ancient 
and Clarksville divisions have not been traced south of Trimble 
county. The characteristic fossils of the Blanchester division 
have not been seen south of the northern part of Jefferson county, 
in Indiana, although the upper part of the Waynesville member, 
as exposed at Madison, is believed to belong to this division. The 
Liberty, however, extends far southward, to the vicinity of Ray- 
wick, in the western part of Alarion county, Kentucky, On the 
eastern side of the geanticline, the Liberty fauna also may be 
traced southward beyond the Ohio River, to Owingsville, in Bath 
county, Kentucky. 
From Bullitt county southward, the upper part of the Waynes- 
ville or the basal part of the Liberty is characterized by the pres- 
ence of numerous specimens of Columnaria, Calapoecia, Tetra- 
dium, and a variable number of specimens oiBeatricea. This
