On May 1, 1889, Dr. N. L. Britton and myself were exphninir th ■■ 

 clay beds'along the Raritan River, at Perth \\mboy, where we found 



other respects identical with the leaf-bearing concretion* from tin- 

 shore at Tottenville. This encouraged us to believe that careful 

 search cm Staten Island would probably yield similar n suits, and such 

 has been the case. 



In October, 1891, I found molluscs in the concretions at Tottenville, 

 and immediately afterwards at Arrochar. These and the ones from 

 Perth Amboy were submitted to Prof. Whitfield and by him identified 

 as Cretaceous species.
