 feo^^S/cr^J^' Acad.^eo/, l^if>. /2.2.H found in 



the bituminous shale of the Albertite (fossil petroleum) district 

 of the Albert mine, Hillsborough, N. Brunswick ; flattened by 

 pressure, but with fins as perfect as in life, and all their scales 

 in place, instead of being scattered about as at.the Joggins and 

 generally elsewhere in the Lower Carboniferous strata ; in fact 

 the fish have been mummified like the old Egyptians in asphalt 

 It is not likely that any such locality will be discovered in 

 Pennsylvania ; but an abundance of the scales of this kind of fish 

 are found in our rocks, and it is well to show the form of the lish 

 that they belong to. 



Palseoniscus brainerdi, Thomas. Bost. Soc. N. Hist. Vol. 

 4, 1853 ; Pal. Ohio Vol. 1, p. 280, where it is said that although 

 the Berea Grit of Ohio is a coarse rock usually barren of all 

 fossils, yet its upper layers at Chagrin Falls contain a large 

 number of this species of fish,- no traces which have been dis- 

 covered elsewhere. See also Pal. Ohio, Vol. 1, p. 346. Mr. G. 

 K. Gilbert, Asst. Geol. Sur. Ohio, discovered in the Berea Grit 

 on Oil Creek (as he understood the rock) in Venango Co., Pa., 

 the most remarkable accumulation of fish spines Dr. New- 

 berry knew, scattered over a detached slab of sandstone, 

 a dozen spines on a surface less than two feet square, all ap- 

 parently belonging to Ctenacanthus triangularis. Other layers
