no flints.

Man and his cotemporaneous animalsand plants. 

 Psammobia fusca. — Ostrea borealis. 



This Newer Pliocene is the recent of Mr. Lyell, j 

 and contains fossil shells, &c, with relics of! 

 the works of man. v { 



Quartzose Sand and Shells, Fusus, Murex, 

 Cypraa, Nassa, Astarte. Voluta Magellanica. 



Land and fresh water shells — cylindrical cases 

 of the Larvae of Phryganea, coated with 

 minute shells — at Auvergne, France, and 

 Italy. This series is wanting in England, 



Contains bones of Mammalia. Turtles, remains 

 of Sword and Saw Fish, marine and fresh 

 water shells. 



This rock as Chalk, is not known on the West- 

 ern Continent ■ but is abundant in Europe, 

 particularly in England, and is characterized 

 by the remains of Zoophytes, Shells, Shark's 

 Teeth, palates of other Fish, Echini, <fcc, 

 &c.

There is in New Jersey at Mount Mitchill, 

 Neversink Hills, and running south into the 

 State of Virginia, a bed underlaying aferru- 

 gineous sand called Marl, which appears to 

 be by its organic remains an equivalent to 

 the Green Sand of Europe — it contains ver- 

 tebrae of the Whale, Shark's Teeth, Coprol- 

 ites, Teeth of Monitors, and many fossil 

 shells, &c. 



This contains what is called the Dirt Beds, and 

 is remarkable for its fresh water and land 

 fossils, its forests of stumps and trunks of { 

 trees — it contains the remains of Mammalia, • 

 Birds, Reptiles, Fish and. Fresh Water Crus- 

 tacea, (Cypris.)
