VINCENTOWN FORMATION. 16 



o 



Farms, the Vincentown sand is well exposed and is highly 

 ^ossiliferous. The bed at this locality is well towards the summit 

 of the formation and has a larger content of glauconite than 

 cither of the other localities which have been mentioned. The 

 iauna recognized at this locality is as follows : 



EchinodErmata. 

 Salenia sp. 

 Cardiaster ductus (Mort.). 



Bryozoa. 



Onychocella digitata (Mort.). 



Pe^lecypoda. 



Nemodon sp. 



Gryplnaeostrea vomer (Mort.). 



Cardium knappi 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 bryo'zoan Onychocella 

 digitaia, 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.
