GASTEROPODA OF THE LOWER GREEN MARLS. 31 
PALEONTOLOGICAL EQUIVALENTS OF THE NEW JERSEY GREEN 
MARLS. 
Of the 222 species of Lamellibranchiates described in Vol. 1, 74 are 
new species, and of the 190 species of Gasteropods 107 are therein described 
for the first time; 70 of these new forms are Cretaceous and 37 are Eocene. 
These new species of course are of no stratigraphic value at the present 
time; further than their generic relations have weight. It will be seen, 
however, from tables Nos. 3 and 4, that the New Jersey Lower Marls must 
be equivalents of the Cretaceous beds found so extensively throughout the 
Southern States, notwithstanding the great difference in their lithological 
character, as so large a proportion of the species have been recognized as 
common to one or more of those localities, 66 species of these classes 
being known from Alabama and other States, as shown in the list below.

In all probability many more Gasteropods may prove common to New 
Jersey and other States when the casts from those places shall have been 
critically compared. It will be seen, therefore, that no reasonable question 
can be entertained of the near equivalency of these beds. Nor can there 
be any question as to the relationship existing between the Crosswicks
