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 outcrop 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. Redjield 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 Chei?'othe?iiitn minuSy 

 which is figured in the Bulletin of the Geological Society of 

 France. 



Mr. Red field also exhibited a new species of fossil fish from 

 Sunderland, Mass., which seems referrible to the genus Palceo- 

 niscus ; and also called the attention of the Association to a dif- 

 ference of structure in the PalcBotiisci of the Sunderland localitTT" 

 from those of Connecticut in the same formation ; while the lat^ 

 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 examina- 

 tions had led him to doubt on this point ; although this genus is 

 more common than PalcEoniscus in the new red formation, both 

 in Connecticut and New Jersey. 



3Ir. Lyell and Mr. B. Silliman, Jr. offered some remarks on 

 Mr. Redfield's observations. 



Mr. John S. Hayes, in explanation of the fossil footmarks in 

 the sandstone of Connecticut river valley, gave some account of 

 the existing species of birds most nearly resembling those sup- 

 posed to have made those tracks.
