It has been seen that Mr. J. H. Redfield considers the other 
specie

Society, show very strong resemblances to two or three of my 
fishes from the sandstone of Connecticut river at Sunderland, to 
one of which I had proposed the name Ischypterus Marsh. Is 
it not probable that the vast extent of sandstone and trap in 
that distant region, is of like age with our Newark group? —
