inferences with which Mr. R.’s paper in the Annals is concluded: 
viz. 
“Tt has of late years been generally admitted that the sand- 
stone from which these fishes are derived is of much later date 
than the old red sandstone, to which it was once referred, and 
these remains confirm this belief. The Paleonisc:, of Europe 
[true heterocerques] have never been found below the coal mea- 
sures, while they extend upward to the copper slate of the zech- . 
stein, or magnesian limestone. In the case before us, we find a 
species of Paleoniscus accompanied by a fish, the structure of 
whose tail approaches that of the Pholidophorus, and of other 
shes never found below the lias. This fact would seem to im- 
ply for this formation, even a higher situation in the series than 
at which is now assigned it by geologists.”—Annals, &c., p. 4 
e American Association of Geologists and Naturalists at 
the meeting held in Albany in April, 1848, requested Mr. John 
H. Redfield to prepare a report on the fossil fishes of the United 
tates. His report was presented to the Association, at New 
Haven, in May, 1845. It was withheld from publication by its 
author, on account of the expected visit of Prof. Agassiz to thi 
country, and with a view of commending the whole subject to 
his examination.—In the review of the fishes of our new red 
sandstone, so called, the report stated as follows: 
“New Rep Sanpstong.—Under this term I include the ex- 
tensive sandstone formation of the Connecticut river valley ; the 
small and isolated basin on the Pomperaug river near Southbury, 
Ct.; the New Jersey Sandstone, extending from the border of 
the Hudson river, southwesterly, to the interior of Virginia ; 
and, also, the formation known as the coal rocks of Eastern Vir- 
ginia.—(Report, p. 4.) 
“All of the fishes hitherto found in these rocks belong to the 
order GaNnorp, and to the family Leprpom£.”—Report, p. 5.
