FOSSIL FISHES. 385 
In concluding the descriptions of such of the living fishes of the State as I have been 
enabled to procure, and which is very far from exhausting the list, a notice of the fossil species 
would appear to be necessary. It is, however, remarkable, that although numerous species 
are found in the neighboring States of Massachusetts and Connecticut on the one hand, and 
New-Jersey on the other, none, until very recently, have been detected in this State.* At 
present, one species only, the Holoptychius nobilissimus, is positively known to be found 
within our limits. The following list may be found useful to the student of our fossil ich- 
thyology. In drawing it up, I have to acknowledge my obligations to J. H. Redfield, who, 
together with his father Mr. W. C. Redfield, have most largely contributed to the stock of 
our knowledge on this subject.

* Since the above has been in the hands of the printer, I have received the following interesting communication from 
Mr. W. C. REDFIELD: 
“ Although the genera Palwoniscus and Catopterus have not been found in New-York, the new red sandstone, or 
“(middle secondary’ of Prof. Rogers, to which they are peculiar, extends through Rockland county from the flank of the 
“ Highlands to the Hudson river, and the boundary line between New-York and New-Jersey, and occurs also in Orange 
county in the vicinity of Long pond. From the position and line of strike of the New-Jersey fish beds, it would ap- 
“ pear probable that these fossils should be found in Rockland county. Two of the fish beds alluded to have indeed been 
« Jately discovered near Ramapo, about ten miles from the State boundary. I have obtained from these beds, two or three 
« new species of Palwoniscus, one of which bears a close resemblance to the P. elegans of Mr. Sedgwick, which is found 
“in the magnesian limestone or new red formation of England.”
