THE CORNIFEROUS FAUNA 425 
Oriskany species used for comparison with the Corniferous 
fauna is the one prepared by Schuchert.*. In this Oriskany list, 
however, the forms occurring only at Cayuga, Ontario, have 
been eliminated, for reasons that will appear later, as they can- 
not be considered as being members of the pure Oriskany fauna. 
In both the lists some changes in nomenclature have been made, 
in accordance with recent usage. Only the genera are recorded, 
the number following each generic name indicating the number 
of species.
