126 CRETACEOUS PALEONTOLOGY. 



Mullica Hill has long been a noted locality for New Jersey 

 Cretaceous fossils. The fossil locality is in the village, the ex- 

 posure being in the hillside just south of the railroad trestle. The 

 section at this point is as follows (Locality 169) from the base 

 upward. 



169^. Yellow or red quartz sand without glauconite, about 20 

 feet exposed at the base of the blliff. The contained fossils are 

 poorly preserved casts, but Belemnitella americana, Gryphaea- 

 and Neithea have been recognized, and the bed may be confi- 

 dently referred to the Mount Lau»el sand. 



169^. Above the yellow sand is a 5-foot, indurated shell bed, 

 filled with fossils. The matrix in which the fossils are imbedded 

 is sandy, with pea-like quartz pebbles, the whole colored dark- 

 green by a considerable percentage of glauconite. The shells of 

 those species which are not represented by casts, have for the 

 most part been replaced by the mineral vivianite, a phosphate of 

 iron doubtless derived from the glauconite. 



169'^. Above the shell bed, a nearly pure greensand marl con- 

 tinues to the summit of the exposure. 



Locality i6p^. — The fauna of the shell bed exposed at Mullica 

 Hill has yielded the following species, although, the list is doubt- 

 less incomplete: 



Anthozoa. 



Paracyaihiis vawghani n. sp. 

 Undetermined coral. 



ECHINODERMATA. 



Cardiaster smocki Clark n. sp. 



Brachiopoda. 



Terehratella plicata^ Say. 



P^tECYPODA. 



Cucullaea neglecta Gabb. 

 Gervilliopsis ensiformis (Con.). 

 Inocerasmus confertim-^annulatus Rocmer.
