Preliminary ISlotes on Cincinnatian and Lexington Fossils 299 
detected readily. Occasional specimens occur destitute of both 
ridges and nodes. These may be only extreme variants of Beatricea 
undulata, and here are figured as Beatricea undulatacylindrica. 
Geological position. Four miles north of Richmond, Kentucky, 
half a mile north of Ophelia, in strata corresponding to the southern 
extension of the Liberty bed as exposed in Boyle, Casey, 
Marion, Washington, Nelson, and Bullitt counties. At Ophelia 
this smooth form of Beatricea is associated v^ith Beatricea u ndulata, 
Beatricea nodulosa, Labechia ohioensis, Columnaria alveolata^ 
Calapcecia cribriformis, Streptelasmavagans, Platystrophia acutili- 
rata, and other fossils. Similar specimens have been found at the 
same horizon immediately west of Fredericktown, in Nelson 
county, and in the northeastern part of Raywick, in Marion 
county, Kentucky; also in'the Elkhorn bed, along Elkhorn creek, 
south of Richmond, Indiana. 
Beatricea nodulifera, sp. nov. 
{Plate VII, Fig. 13; Plate Fill, Fig. 5 .) 
Cylindrical stems with nodes more or less irregular in arrange- 
ment, but tending toward arrangement in vertical rows with a 
slight spiral twist around the stem. In specimens in which this 
arrangement in vertical rows is most pronounced, some of the 
nodes are connected sufficiently to suggest vertical ridges separ- 
ated by more or less irregular furrows. The lateral distance 
between these rows or ridges varies from 5 to 7 millimeters. In 
other specimens, the arrangement is more irregular. Specimens 
50 millimeters in diameter have been collected, and the species 
is known to attain a larger size. The stems were several feet in 
length and grew in a vertical position, tapering slowly toward 
the top. 
Geological position. The type specimens were obtained five 
feet below the base of the Devonian limestone, at a small falls a 
quarter of a mile south of the Sulphur Spring, three miles south 
east of Lebanon, Kentucky. Here Columnaria and T etradium 
occur within three feet of the base of the Devonian limestone, 
and Beatricea nodulifera, Beatricea undulata, Heterospongia sub- 
ramosa, and Columnaria occur two feet lower. This horizon is 
regarded as the base of the Liberty bed. Specimens have been 
found at the same horizon at BardstoWn, Ky.
