S. Stanton, who kindly turned the specimen over to me. This 

 locality is at the extreme opposite end of the island to Tottenville, 

 the only other place where fossil leaves had been found, so that, as 

 in the case of the Pachycardium, the importance of the find was 

 not realized at the time, and the opinion was expressed l)y me that 

 it was probably of drift origin (Proc. Nat. Sci. Assn. S. I. Dec. 8, 

 1888). 



Outcrops of what were apparently cretaceous clays and gravel 

 were next discovered on the shore and in the ravine at Prince's 

 Bay, on the shore at Eltingville, and in an excavation on the north 

 side of the Fingerboard Road at Clifton. In the meantime the 

 material from Tottenville was accumulating, some of the specimens 

 being in such an excellent state of preservation that the species of 

 leaves could be accurately studied and determined, leaving no 

 question as to their cretaceous age. No animal remains had as yet, 

 however, been discovered, if we except the single Pachycardiumi 

 previously mentioned. 



On May 1, 1889, in company with Dr. Britton, we were examin- 

 ing the clay beds along the Raritan River at Perth Amboy, N. J. 

 Here we found ferruginous sandstones and concretions containing 

 molluscs, but in all other respects identical with the leaf-bearing 

 concretions from Tottenville. This encouraged us to believe that 

 careful search on Staten Island would probably yield similar results, 

 and such has been the case. In October of last 3^ear (1891), I 

 found molluscs in the concretions at Tottenville, and, during the 

 same month, specimens were also found at Arrochar. These and 

 the ones from Perth Amboy were submitted to Prof. Whitfield, and 

 were, by him, determined to be marine cretaceous species. 



Finally, in the following month, I found well-preserved fossil 

 leaves of undoubted cretaceous species on the shore at Prince's Bay, 

 an intermediate locality on the south shore of the island, in con- 

 cretions, in all respects similar to those from Amboy, Tottenville, 

 and Arrochar. 



Following is a list of the molluscs as far as they have been 

 identified : — 



Corhiila sp? (possibly a new species), Perth Amboy. 

 Pnchi/cardiiim Burlingtonense, Whitfield, Tottenville. 

 TerehrufeJ/d Vaniixemi, Lyell and Forbes, Tottenville. 

 Terebratulina Atlantica, Say, (?) Tottenville. 

 Cardium (^Criocar^diurii) dumosutn, Conrad, Arrochar. 

 Ostrra jilumnsn, Morton, (?) Arrochar. 

 Ap/irndiiia Tip/inna, Conrad, (?) Arrochar. 

 This latter may be CaUista Deliiiixirensis, Gabb. 

 Grjjphuia sp (?) (a young specimen) Arrochar. 



There are also some two or three other species which are too im- 

 perfect for determination. 



The plant remains are far more numerous. In some instances 

 the stone is composed entirely of a mass of vegetable ddbris 

 cemented together with limonite. In almost every one of the
