bophora, the two latter marine and specifically unidentifiable and 

 the six former brackish in type and of doubtful generic relations.' 



Dr. Stuart Weller in his admirable investigation of the New Jersey 

 Cretaceous did not actually collect any of these forms and all are 

 based on single occurrences mostly of ancient date made when the 

 importance of definiteness regarding exact localities was not appre- 

 ciated. None have been subsequently collected, although the number 

 of openings in this area is very great; the region is visited annually 

 by numerous geological students and it is a common practice for the 

 workmen to save unusual objects such as fossils which they find and 

 these usually find their way into the hands of collectors visiting the 

 clay-pits. 



The Astarte is listed on the authority of Conrad, the Ambocardia, 

 Rangia, and the two Corbiculas on the authority of Whitfield, and the 

 Turritella and Cymbophora on the evidence of a single slab of sand- 

 stone in the State Survey collection obtained over twenty-five years 

 ago and said to have come from Sayreville. It will be obvious that 

 evidence of so scanty and indecisive a character is hardly to be given 

 much weight. 



CONCLUSIONS 



1. The Raritan fliora is clearly shown to be of Upper Cretaceous 

 age. 



2. It is shown to be very similar to, but somewhat older than, the 

 flora of the Dakota Group, and to be identical with widely scattered 

 floras usually regarded as of Cenomanian age. 



3. It is shown to be totally distinct from the known flora of the 

 Montana Group.
