THE MERCHANTVILLE. 53 



southwest, along the strike of the Cretaceous beds, from James- 

 burg, much of the intervening region being too heavily drift- 

 covered to permit the examination of the underlying Cretaceous 

 beds. From the shores of Raritan Bay, the locality is distant 

 over 50 miles. This locality has been frequently visited by col- 

 lectors from the Philadelphia Academy of Science, and many 

 fossils from here are preserved in the collections of that insti- 

 tution. In the following list an attempt has been made to make 

 the list of the Lenola fauna as complete as possible, and a few 

 species have been included which have been seen by the writer 

 only in the collections of the Philadelphia Academy. All such 

 species are designated by an asterisk (*).
