378. L. Lesquereut on the Coal Formations of N. America. 
Sigillaria® are found at Paradise, on Green river, Kentucky, in 
the shaly or ‘brashy’ coal separating No. 12th coal from an iron 
blackband which overlies it. I must not omit to mention with 
vules of its leaflets emerge from the common rachis. ; 
The third great sandstone formation, or the Anvil-rock sand- 
stone, which underlies the highest section of the coal-measures, 
is from all appearance as distinct a point of division in the dis- 
tribution of the fossil flora as any one of the other great sand- 
stones, the conglomerate and the Mahoning. From my own 
observations and from the data collected by other geologists, 
especially by my friend J. P. Lesley, no trace of Lepidodendron 
aeons either in the Anvil-rock sandstone or in the measures 
aboveit. At least, none has been found as yet. This sandstone 
The surface of the tree and of the roots is marl®d by peculiar 
scars. ‘T'hough not perfectly distinct, it was at once evident that 
this fossil tree did not belong to any of the genera of plants be- 
fore seen in the coal. It was nevertheless impossible to describe r 
it, in its state of obliteration. Later, Dr. D. i

rock sandstone of Posey Co., Indiana, not far from the Wabash

one foot thick, branching at its base in five or six large roots, di- 
verging nearly horizontally. Its surface is narrowly reticulated, 
and is marked by double oval scars, united by a deep wrinkle, 
very regular in their position, and about one inch distant from
