276 On the occurrence of Fossiliferous Strata in the {Match 
similar to those of the Ithaca and Chemung groups but in greater 
number and frequency, and giving rise to thin seams of coal, 
none of which, however, exceed a foot in length and breadth and 
an inch in thickness.” 
Professor H. D. Rogers (Geol. of Penna., Vol. 1, p. 108) says of 
these same beds: 
“This is a mass of very thick alternating red shales and gray 
and red argillaceous sandstones. It has very few organic remains. 
mong these is the Holoptychius and one or two other remarkable 
fossil fishes of genera distinctive of the Old Red Sandstone.” 
Professor Dana (Manual, 1874, p. 278) says: | 
“ The rocks (Catskill) afford but few relics of life.” |

“ Among animals, no corals, crinoids, brachiopods or trilobites 
are yet known. The coarse character of the beds accounts for 
their absence. There are some lamellibranchs and a Euomphalus! 
these with fragments of fishes make up about all that is ye 
known respecting the fossil contents of the beds.” 
Mr. S. A. Miller, in his catalogue of the American Palzeozoit
