Giving a total of 441, or deducting the two-.naticas and grypheea, which 
are counted also in the Middle Marls, a total of 428 described species. 
Were the localities critically examined many others would undoubtedly be 
obtained, as a number of casts are already recognized as distinct from any 
of the described forms, both in the Cretaceous and Kocene beds. 
Of the Brachiopoda above enumerated the Terebratula Harlani and 
Terebratulina lachryma are also known to occur in South Carolina, and 
T. floridana is common at some localities in Alabama. Of the Lamelli- 
branchiates of the Lower Marls, three species are known in Europe, and 
the number attributed to certain American States are as follows:

A large number are found in States not here mentioned. Six of those 
from the Middle Marls also oceur in other States, and but one species from 
the Eocene layers, Crassatella alta, is known to occur outside of New 
Jersey. In Table No. 3, the species which have been thus cited are given 
under the States wherein they are found, and the succeeding table, No. 4, 
gives the same for the Gasteropoda and Cephalopoda, few only of which 
have been recognized beyond the State.
