F. H. Bradley on Fish-remains in Western New York. 71 
Mr. Green to increase my collections. The specimens thus ob- 
tained are sufficient to indicate the. distence of at least two or 
three species of on and to show the principal characters of one 
ofthem. It ish oped that further explorations, now in progress, 
will be still more successful. 
The most common species has a —_ or three-forked tooth, 
inches across (probably a distinct species). One large, aicimad 
interior, bone measures three by four inches, with a thickness, 
at one end, of over an inch. One jaw is between three ‘iad 
four inches lon ng. 
ese remains all retain their bony structure, though some of 
the larger and more porous fragments are thoroughly permeated 
with the pyrites. 
Accompanying these remains are very numerous shells 
readily from the rock, with very brilliant sur 
A few of the Orthocerata retain their malin structure, 
and also have their cavities mostly filled with calcité. The . 
same mineral is ee — in the interior of the ’ Goniatites 
which are common i . 
Of Goniutites, eare: are at jonas three species, — a@ very 
minute form which I am inclined to call the young of G. uni- 
angularis, but which ae prove distinct. Of eS 
we have twelve or fifteen species; probably as many Lamelli- 
branchs; and five or six Brachiopods. Excepting the Goni- 
atites, which are sometimes two ee across, the shells are 
all minute. 
A few specimens of three or four small species of epiedyeee- 
have been found, and the stems of la: : ere are qui 
common in some layers. Corals are very r 
Many of the species will very cer na i ssesiew riba with 
those which crowd the Hamilton blue shales, but I have reason 
to think that most of them are new. No careful examination 
and comparison have as yet been made; but I hope that it may, 
ere long, be completed, and the results published.
