 with one another and with those of Western Europe, with Annotations.

The Eocene beds of Virginia are placed in tlie Chicliasawan stage near tlae base of 

 the Eocene and correlated with the Suessonian of Europe and the Miocene deposits are 

 correlated with the Helvetian beds of Europe.

 Virginia. 



Abstr. Geo]. Soc. Anier. Bull., vol. ix, pp. 414-416. 



The presence of marine Cretaceous shells is reported in a deep well at Norfolk 

 between the depths of 715 and 77.5 feet and at Lamberts Point between 56.3 and 616 feet.

Glekn, L. C. The Hatteras Axis in Triassic and Miocene Time. 



Amer. Geol., vol. xxiii, pp. 375-379, 1899. 



The view is expressed that the region in the vicinity of Cape Hatteras was not 

 submerged during early Miocene time and this accounts for the discontinuity of tlie 

 lower Miocene deposits of Virginia with those of the Carolinas. 



AVoolman, Lewis. Artesian Wells. 



Ann. Kept. X. J. Geol. Survey for 1898, pp. 121-12G, 1899. 



Records of two artesian wells in the Coastal Plain of Virginia are given, one at Fair- 

 port in Northumberland County, and the other at Old Point Comfort. Marine Cretaceous 

 fossils were found at depth of 640 feet at Fairport and at depth of 840 feet at Old 

 Point Comfort. A list of Miocene forms from latter well is also given. 



Fossil Mollusks and Diatoms from the Dismal Swamp, Virginia 



and North Carolina; Indication of the Geologic Age of the Deposits; with 

 Notes on the Diatoms by Charles C. Boyer. 



Proc. Acad. Nat. Sci., 1898, pp. 414-429, 1899. 



Forty-nine species of mollusca were obtained form the Dismal Swamp near Wallace- 

 ton and Suffolk. Of these 7 species are Pliocene and pre-Pliocene forms, IG species range 

 from Miocene to Recent; 14 species are found in both Pliocene and Recent deposits; and 

 12 species are Pleistocene or Recent. From these facts the author concludes that the 

 fossiliferous deposits underlying the Dismal Swamp are not older than late Pliocene and 

 may be Pleistocene in age.
