Preliminary Notes on Cincinnatian and Lexington Fossils 293 
trica, Modiolopsis pholadiformiSj Opisthoptera fissicosta^ and 
Pterinea demissa. In addition to these, Rafinesquina loxorhytts 
is abundant. Now, as a matter of fact, a very similar assemblage 
of fossils occurs in the upper part of the Arnheim bed in the 
eastern part of Indiana and suggests the idea that the Fort Ancient 
division of the Waynesville bed belongs with the upper part of the 
Arnheim, rather than with the Clarksville and Blanchester divi- 
sions of the Waynesville bed. The first specimens of Bythopora 
meeki were noticed 28 feet above the base of the Fort Ancient 
division, but it may occur lower. The Richmond form of Platy- 
strophia laticosta comes in 7 feet below the base of the Orthoceras 
fasten zone. 
The lower part of the Garrard sandstone of central Kentucky 
consists of massive argillaceous and more or less siliceous fine- 
grained limestones, with few fossils, differing conspicuously from 
the thinner bedded argillaceous limestones, interbedded with con- 
siderable clay, which overlie it and form most of the upper part 
of this Garrard sandstone. To the lower, massive part the nam^ 
Paint Lick bed was applied. The overlying part was correlated 
with the Mount Hope bed on account of the presence of Stropho- 
mena maysvillensisy and other fossils which northward begin their 
range with the Mount Hope bed. The lower or massive part, 
called the Paint Lick bed, was correlated with the upper Eden, 
because it was believed that it could be traced stratigraphically 
northward into beds containing D ekay ell a ulrichi and other charac- 
teristic Eden fossils. 
The underlying Eden beds in central Kentucky, were included 
in the Million bed. This bed includes the southern continuation 
of the Southgate bed and, at its base, a peculiar fauna including:
