26 CRHTACEOUS PALEONTO'LOGY. 



of the "Middle Marl," and. the base of the "Upper Marl." Clark 

 included this bed at first with the "Upper Marl" in his Manas- 

 quan formation. Later, however, he removed it entirely from 

 the Cretaceous and considered it as of Miocene agfe.^ The writer, 

 after finding an abundance of Cretaceous fossils in the formation, 

 referred this sand definitely to a position in the Cretaceous, it 

 being the exact equivalent of the Vincentown limesand, and this 

 interpr^ation has been assented to by Dr. Clark. 



It is believed that the following Table IV is a representation 

 of the stratigraphic divisions of the Cretaceous formations of 

 New Jersey to which all who have studied the region will assent. 

 The fO'rmations have not been grouped in any major divisions, 

 for in New Jersey, at least, any major stratigraphic grouping is 

 of doubtful utility. An arrangement of the 'formations will be 

 discussed later, after a treatment of the faunas themselves.
