VINCENTOWN FORMATION. 163 



Farms, the Vincentown. sand is well exposed and is highly 

 fossiliferous. The bed at this locality is well towards the summit 

 of the formation and has a larger content of glauconite than 

 either of the other localities which have been mentioned. The 

 fauna recognized at this locality is as follows : 



ECHINODERMATA. 

 S edema sp. 

 Cardiaster cinctus (Mort.). 



BRYOZOA. 



Onychocella digitata (Mort.). 



PELECYPODA. 



Nemo den sp. 



Gryphaeostrea vomer (Mort.). 



Cardium knap pi n. sp. 



A few rods down the stream from where the above fauna was 

 collected, a bed in the same formation was recognized which is 

 completely filled with examples of the bryozoan Onychocella 

 digitata, with some plates and spines of Echinoids, the association 

 being exactly that which is often seen in the Vincentown lime- 

 sand, although the matrix in this case is a quartz "and glauconitic 

 sand with no lime. 



Locality 146. In the side of the road crossing Crosswicks 

 Creek a little over i mile north of New Egypt, a yellow sand is 

 well exposed on the west side of the creek, which has all the 

 lithologic characters of the Vincentown sand in some of its ex- 

 posures further east. At this point, however, the sand is appar- 

 ently well down in the formation near the top of the subjacent 

 Hornerstown marl. The fossil species recognized at this locality 

 .are : 



BRACHIOPODA. 



Terebratula harlani Mort. 



PELECYPODA. 



Gryphaea sp.
