Crab Orchard, east of Cedar creek, belong to the same horizon. 
It is an abundant fossil at the base of the Saluda bed in Jefferson 
and Ripley counties, in Indiana. At the top of the Saluda bed it 
occurs at numerous localities in Jefferson county, Indiana. In 
the Elkhorn bed it occurs both in Indiana and Ohio. 
Columnaria alveolata, Goldfuss. 
{Plate XI, Fig. 3.) 
This species is readily distinguished in the region of the Cincin- 
nati geanticline by its conspicuous septa, half of which almost or 
quite reach the center of the corallites. 
Geological position. In the lower part of the Liberty bed this 
species may be traced from Jefferson county to the middle of Casey 
county, Kentucky. It occurs at the same horizon four miles 
north of Richmond and between Stanford and Crab Orchard. 
Large specimens occur half way between Peewee valley and 
Brownsboro, presumably at the same level. Lrom Hanover and 
Madison, Indiana, as far north as the exposures two miles north- 
east of Osgood, they occur at the base of the Saluda bed, in some 
localities abundant, at others very rare. The specimens found 
by John Misener near the base of the exposures below Richmond, 
Indiana, probably came from the Liberty horizon. Lrom the 
western part of Henry county, in Kentucky, to the northwestern 
edge of Nelson county, specimens also identified as Columnaria 
alveolata are common locally at one horizon in the lower part of 
the Waynesville bed. At Concord, Kentucky, specimens of 
Columnaria alveolata occurred not onlv at the base of the Liberty 
bed but one specimen was found also near the base of the Waynes- 
ville bed, associated with Streptelasma vagans., 5 feet above the 
Strophomena concordensis horizon. At Clifton, Tennessee, 
several specimens occurred in the Arnheim bed. Columnaria alveo- 
lata occurs near the base of the Liberty bed in Stony Hollow, 
northwest of Clarksville, Ohio. One specimen was found loose 
in the upper or Blanchester division of the Waynesville bed, at 
the Blacksmith Hollow northeast of the railroad station at Ore- 
gonia. Along Elkhorn creek, south of Richmond, Indiana, small 
specimens of Columnaria alveolata, associated with small speci- 
' mens of Columnaria vacua, occur 14 feet below the Brassfield 
or Clinton bed, in the Elkhorn bed. Several poorly preserved
