further confirmed by the appearance of the strata in some parts 
of the district, where in consequence of the removal of the sedi- 
mentary rocks from a narrow space entirely across the tract, he 
was able to trace the beds from their outerop nearly to the bottom 
of the trough in which they were deposited. In this case, he 
found the inclination of the beds to continue unchanged down- 
wards, instead of becoming more gently inclined towards the 
bottom, as might be expected on the hypothesis of an originally 
horizontal position with a subsequent uptilting movement. 
Mr, Redfield spoke of fossil rain-marks of a very perfect char- 
acter which he had observed with Mr. Lyell, at the quarries of 
new red sandstone near Newark, N. J. He also gave notice of 
the discovery of a new species of fossil footmark in the new red 
sandstone of Connecticut. The specimen which he had seen 
was found in the well known quarries at .Portland, (formerly 
Chatham,) by Mr. Russell, one of the proprietors, and is now in 
the possession of Dr. Barratt of Middletown. These footmarks 
are wholly unlike the Ornithichnites described by Prof. Hitch- 
cock, some of which have been found in the same quarries ; but— 
they have some little resemblance to the Cheirotherium. MINUS, 
which is figured in the Bulletin of the Geological Society of 
France. SS Si es ee 3 
Mr. Redfield also exhibited a new species of fossil fish from 
Sunderland, Mass., which seems referrible to the genus Paleo- 
niscus ; and also called the attention of the Association to a dif- 
ference of structure in the Palgonisci of the Sunderland locality 
from those of Connecticut in the same formation ; while the Jat- 
ter have a perfect resemblance to the fossil fishes of New Jersey. 
He had also discovered an apparent error in his own printed no- 
tice of American fossil fishes, in having named Sunderland as 
one of the localities of the genus Catopterus, as further examine- 
tions had led him to doubt on this point ; although this genus-is 
More common than Palconiscus in the new red formation, both 
in Connecticut and New Jersey. t Set
