Mr. Murchison’s report was not then published, and consequently 
these fossils could not be identified with the Annelides there de- 
scribed. On seeing this work Dr. J. had been able so to identify 
them, and he now concurred in the views expressed concerning 
them by Prof. Hubbard. , 
Prof. Mather stated that he had found an entire analogy in the 
fossils of the slates on the Hudson river, in Rensselaer and Sara- 
aes 
Mr. W. C. Redfield made some observations concerning the 
~ fossils in the flagging slates employed in the city of New York. 
‘These slates are generally obtained from the counties of Greene 
and Ulster, N. Y. He referred to the corner of Cedar street and 
Broadway, and to the walk in front of the Spring street church, 
near the Hudson, as exhibitions of these impressions. 
Prof. H. D. Rogers observed, that the pavement in front of 
the United States Bank, (Philadelphia,) afforded a similar exh- 
bition. 
_.. Dr. Jackson now offered some general remarks upon the ge 
ology of the states of Maine and New Hampshire. 
At 12 o’clock the Association adjourned, as a mark of respect

States, whose funeral took place at this hour. :

Mr. W. C. Redfield laid on the table sundry specimens of fos 
fishes found in the red sandstone formations of Connecticut, 
Massachusetts, and New Jersey.* 
_ Of eight species from these formations comprised in the collection, five 
. species are found to belong to the genus Paleoniscus, and three species 
_ tothe genus Catopterus. It is remarkable that nearly all of these several 
species are common to most of the known localities of these fossils in the 
above mentioned states. The importance of this fact, as aiding to estab- 
lish the cotemporaneous character of these formations, induced Mr. R. t 
place this collection before the Association.
