Prof. Jeffries Wyman exhibited some portions of Fossil 

 Bones, from the Sandstone of the Connecticut Valley. 



They had been examined twenty-five years ago, and were 

 recognized as bone by Mr. Ellsworth. Fifteen or sixteen speci- 

 mens had been recently sent him for examination, but they were 

 mostly in very small fragments. Only one or two give any 

 clue to the nature of the animals to which they belonged, but 

 one, which he exhibited, he had found to be a vertebra, with 

 portions of other vertebrse in front of and behind it. This verte- 

 bra presented two important features, viz : a transverse and an 

 inferior spinous process. This proved the bone to have belonged 

 to a higher class of animals than fishes. A concave extremity, 

 and other markings, make it pretty evidently correspond to the 

 vertebra of a reptile, possibly to an anterior caudal vertebra of a 

 Saurian. In one or two specimens, a transverse section pre- 

 sented a large cavity surrounded by a thin wall, — a structure 

 rather resembling that of the bone of a bird than of any other 

 animal. 



The greatest improbability connected with the subject is, that 

 the remains of birds and reptiles should be found mingled to- 

 gether in the same formation. They are certainly not mammal, 

 but Dr. Wyman has not much hesitation in pronouncing some of 

 them reptilian. 



The Cabinet Keeper reported, that Mr. E. Samuels, who 

 had been sent by the Society for the purpose, had procured, 

 from Truro, Cape Cod, two complete skeletons of the Black- 

 fish {Globicephalus melas, De Kay,), two lower jaws of the 

 same animal, two crania of the Lophius Americanus, 

 and several specimens of reptiles, fishes, &c. ; amongst 

 them, some toads from the salt water marshes of Truro. 



Mr. Samuels has also discovered, upon the inside of the 

 Cape, at Truro, a fossiliferous bed of green sand, and has 

 obtained a collection of shells from it. Amongst them, 

 are Venus mercenaria, Mya arenaria, and Ostrea Virgin- 

 iana. Mr. Bouve refers this deposit to the Post-Pliocene 

 formation.
