in Ohio and Indiana. In the Liberty bed similar forms are com- 
mon in Ohio and Indiana, and at the more northern localities in 
Kentucky. Southward, along the eastern side of the Cincinnati 
geanticline, at Wyoming, Owingsville, Howards Mill, it is con- 
fined to the base of the Liberty. The specimens found at the 
Merritt ferry, at the mouth of Red river, near College Hill, and 
Cobb Ferry, in Madison county, probably belong to about the 
same horizon. They occur at the base of the Liberty at Ophelia, 
north of Richmond. They occur in the Liberty bed also on the 
western side of the Cincinnati geanticline, as far south as Marion 
county. This may be the horizon also of the specimens found 
on Fishing creek, east of Somerset, in Pulaski county. In the 
upper or Blanchester division of the Waynesville bed Streptelasma 
vagans is common in Ohio, Indiana and northern Kentucky, 
although associated with Streptelasma dispandum which locally 
almost replaces the former species. Occasional specimens occur 
below the chief Columnaria layer, which forms the base of the 
Liberty bed, also in the vicinity of Bardstown, Kentucky. They 
are quite abundant at several horizons in the lower part of the 
middle or Clarksville division of the Waynesville bed in Clinton 
and neighboring counties, in Ohio. At Concord, Kentucky, they 
occur both 5 feet above and 5 feet below the Strophomena con- 
cordensis layer which there forms the base of the Waynesville bed . 
Streptelasma insolitum, sp. nov. 
{Plate Z, Fig. 3.) 
A small and relatively slender form of Streptelasma occurs 
occasionally in the Whitewater strata, along their southern edge 
of exposure, in Decatur, Jennings, and Ripley counties, in Indiana. 
The type specimen, from the Whitewater bed, a mile and a half 
southeast of Westport, on the east side of Painter creek, does not 
preserve the sides of the calyx, but the septae leave a central area 
of only about 4 millimeters for the base of the calyx, the diameter 
of the coral at this level being 18 millimeters. A similar specimen 
was found at the same horizon about two and a quarter miles 
south of Versailles, opposite the home of Porter Harper.
