Locality 14^. — This locality is situated about ^' of a mile 

 south of the last, and about 2% miles northwest of New Egypt. 

 The beds are the lower portion of the Navesink marl and are 

 exposed in the bank of a tributary of Crosswicks Creek which 

 joins the main stream almost opposite the mouth of Lahaway 

 Creek, just east of the wagon road, about J^ of a mile from 

 Crosswicks Creek. Several distinct beds may be recognized. 



147^. This is a gray sand exposed in the bank of the creek 

 about 90 yards east of the bridge. No fossils were obtained from 

 it and its depth was not determined. It should probably be re- 

 ferred to the Wenonah sand. 



147^. This is a gray, arenaceous bed, one foot in thickness, 

 with very little glauconite, containing vast numbers of Belemni- 

 tella, Gryphaea and Hxogyra, examples of all these species being 

 of exceptionally large size. The number of species present in 

 the fauna is small, as follows : 



PEEECypoda. 



Ostrea falcata Mort. 

 Gryphaea convexa M'ort. 

 Bxogyra costata Say. 

 Neithea quinquecostata (Sow.). 



Cephalopoda. 



Belemnitella ■ americana Mort.
