Preliminary Notes on Cincinnatian and Lexington Fossils 301 
There are seven arms, approximately cylindrical at their bases 
horizontally flattened near the ends, but this flattening may have 
been due to crushing. There is no evidence of geniculate bend- 
ing of the arms as in Brachiospongia digitata. The upper surface 
of the specimen, both in the region of the body and arms, con- 
tains numerous fragments of shells indicating either that the speci- 
men was hollow, or that it consists only of an impression of the 
lower side of the original animal. The first view is favored at 
present. 
Geological position. In the southern extension of the Mount 
Hope bed, about a mile north of Paint Lick, in Madison county, 
Kentucky At this point a road turns off* westward from the 
Richmond pike and follows the northern side of a small stream 
entering Paint Lick creek. About 80 feet below the top of the 
section exposed along this road, Strophomena maysvillensis and 
Constellaria jlorida are very abundant. Below this is a series of 
argillaceous limestones interbedded with clay, about 30 feet thick, 
referred to the Mount Hope bed. This is the upper part of the 
Garrard sandstone of Marius R. Campbell. Brachiospongia 
Icevis occurs two and a half feet above the base. The lower, 
massive part of the Garrard sandstone, regarded as the equivalent 
of the upper part of the Eden, equals at least 66 feet at this locality. 
To this lower part the name Paint Lick bed has been given. 
In the Monograph on the Brachiospongidce, Memoirs of Pea- 
body Museum, volume 2, part i, published in 1889, Prof. Charles 
E. Beecher published the following description of -a specimen 
found in Spencer county, Kentucky: 
A specimen of Brachiospongia found by W. M. Linney in the 
northern part of Spencer county, Kentucky, in strata of the 
Middle Hudson series, offers some points of difference with those 
from Franklin county. It is preserved in mudstone, and the 
parenchym of the sponge has been replaced by calcite. The 
specimen measures 235 millimeters in diameter, and has eight 
arms, which are. constricted at their origin, directed outwards and 
downwards at an angle of forty-five degrees, and are not genicu- 
lated as in typical Brachiospongia digitata. The osculum is 
suborbicular, and the neck is campanulate below. The cup, or 
body, of the sponge is comparatively small. The base is flat, and 
without the initial projection usually present. Were it not for 
the great range of variation shown in the specimens from Franklin
