of interest from this very fact as will be noted later. While en- 
gaged in labelling these same collections in the past year, the spec- 
imens have been reexamined and a number chosen for illustration. 
In 1886 also, I received for study from Prof. W. S. Hoskinson of 
Wittenberg College, Springfield, Ohio, a number of corals found 
at Brown’s Quarry, west of New Carlisle, Ohio, of which this pa- 
per includes a tardy account. Prof. Edward Orton, State Geolo- 
gist of Ohio, also sent to me a number of corals from the Clinton 
group of Ohio, the precise locality of which had been lost, but the 
lithological character of which places their geological horizon be- 
yond possibility of doubt. A very good series of specimens has 
been sent to me during the past year by Prof. A. H. Young of Han- 
over College, Hanover, Indiana. He has very kindly furnished 
me with a series of notes on the occurrence of these fossils near 
Hanover, accompanied by photographs of the fossil localities. 
Since this is the first instance in which the Clinton has been iden- 
tified in Indiana by a careful study of its fossil remains, the fol- 
lowing extracts from Professor Young’s notes are added. 
“Fossils are found at two localities : one is in front of the col- 
lege building at Hanover, forming part of a very high bluff, over- 
looking the Ohio river, and one-fourth to a fifth of a mile distant 
from the same. The college is about six miles down the river 
from Madison, Ind. The hill is 315 feet high. In front of the 
college are several thin layers of white, non-fossiliferous lime- 
stone, resembling the typical white limestone of the Niagara found 
higher up the bluff. The Clinton fossils occur in a layer 10 to 14 
inches thick about 275 feet above the river. Below this layer is a 
clierty stone, with conchoidal fracture, 6 or 8 inches thick, non- 
fossiliferous. 
The same strata were traced along the side of a deep gorge to a 
waterfall, three-quarters of a mile from the river. At the top of 
the water-fall are several layers of limestone, passing at a still 
higher elevation into the Niagara limestones. Below this lies the 
fossiliferous Clinton rock, 12 to 20 inches thick. Next comes the 
clierty rock, 2 or 3 feet thick, supposed to contain stromatoporoids 
here. Below the clierty bed is a series of drab, non-fossiliferous 
limestones 20 feet thick, believed to belong to the Clinton. Be- 
neath are 8 to 10 inches of a blue shale in which fossils were found 
by Prof. F. H. Bradley, several years ago, thought to belong to 
the Medina. From this point down to the river, a distance of 235
