One might conclude at once that this shale is little later than the 
Genessee but what seems like a well- warranted conclusion is quickly 
disturbed by the facts known concerning the subjacent strata in north- 
ern Ohio. 
As above stated the Bedford reposes on the Black shale in central 
Ohio, but along Lake Erie two important members are interpolated, 
viz. , the Cleveland and Erie shales. 
Dr. Newberry has decided that the Bedford shale is carboniferous 
on the basis of such fossils, as Syringothyris lypa, Hemipromtes crenis- 
tria, Chontcs logani, Orthis michelina., and Spiriferina solidirostjis and 
a lew more. Having searched dn the same localities without finding 
these forms in the typical Bedford as it appears in southern Ohio and 
on the other hand finding the species above mentioned we feel some 
hesitation as to the occasion of the confusion. These species may in- 
deed occur below the Berea, but in flags and greyish shales not in the 
blue or red Bedford .shale I 
■^'Species so designated are of Hamilton age or closely related to such spe- 
cies.
