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 bluff. Th contained fossils are 

 poorly preserved casts, but Beletnnitella americana, Gryphaea 

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

 dently referred to the Mount Laurel 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 most part been replaced by the mineral vivianite , a phosphate of 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. 



i69 3 . Above the shell bed, a nearly pure greensand marl con- 

 tinues to the summit of the exposure. 



Locality i6p 2 . The fauna of the shell bed exposed at Mullica 

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

 less incomplete: 



ANTHOZOA. 



Paracyathus vawghani n. sp. 

 Undetermined coral. 



ECHINODERMATA. 



Cardiaster smocki Clark n. sp. 



BRACHIOPODA. 



Terebratella plicata Say. 



Cucullaea neglecta Gabb. 

 Gervilliopsis ensiformis (Con.). 

 Inocercbmus confcrtim^annulatus Roemer.
