164 Association of American Geologists. 



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- 

 toga counties, and in the western parts of the state. 



Mr. Vanuxem confirmed the statements of Mr. Mather in re- 

 ,gard to the identity of these slates. 



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 exhi- 

 bition. 



Dr. Jackson now offered some general remarks upon the ge- 

 ology of the states of Maine and Nev/ Hampshire. 



At 12 o'clock the Association adjourned, as a mark of respect 

 to the memory of General Harrison, late President of the United 

 States, whose funeral took place at this hour. 



April 7th, 1 o'clock, P. M. — The Association met, Prof Silli- 

 man in the chair. After the transaction of some ordinary busi- 

 ness, 



Mr. W. C. Redfield laid on the table sundry specimens of fos- 

 sil 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 

 to the 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. to 

 place this collection before the Association. 



Mr. R. stated that the lithological appearances of the shales in which 

 the fossil fishes are found, as well as of the more minute and undeter-
