FISHES OF THE CARBONIFEROUS SYSTEM. 85 
place of residence. These attracted the attention of Prof. Edward Orton, 
through whom I received a number of interesting things which led me to 
open a correspondence with Mr. Way. This would probably have resulted 
in the accumulation of a large amount of new material, but his death ar- 
rested the flow of knowledge from that source, and as he alone knew the 
localities that had furnished his specimens, the visits of other collectors to 
that region have been for the most part fruitless. 
About ten years since Mr. F. A. Randall discovered in a Chemung 
conglomerate at Warren, Pa., a considerable number of the teeth and bones 
of fishes, though generally in a rolled and broken condition. Subsequently 
a collection of similar character was made at the same place by Mr. Charles 
E. Beecher, of Albany. Both these gentlemen have been kind enough to 
send their collections to me for examination, and I have described from 
them a number of new species. 
Mr. Andrew Sherwood, of Mansfield, Tioga County, Pa., who has been 
from childhood an enthusiastic collector of fossils, has from time to time 
obtained fish remains from the Chemung of that neighborhood; one of 
these forms the type of the genus Heliodus, to which further reference will 
be made. Finally Mr. A. T. Lilley, of Le Roy, Bradford County, Pa., has 
found many fish remains in the Chemung group near his place of residence, 
and among them the representatives of several new genera and species, of 
which brief descriptions are given on’the succeeding pages. 
Order DIPNOI. 
Genus HELIODUS, Newb. 
Many years since Mr. Andrew Sherwood discovered in the Chemung 
rocks of Tioga County, Pa., the palate tooth of a fish which I have de- 
scribed! and made the type of a new genus, to which I gave the above name. 
P. J. Van Beneden describes? the palate tooth of a fish which is without 
doubt generically identical with that found by Mr. Sherwood, but it is very 
much larger, the former being less than two inches in diameter, while the
