92 CRETACEOUS PALEONTOLOGY. 



Navesink marl (Locality 126). The section at this point, as 

 made out by the writer is as follows, beginning at the base : 



126^. Gray sand with dark clay bands i to 3 inches 

 in thickness interbedded in the upper portion,- 3 feet. 



126^. Variegated red and yellow sand with many 

 cylindrical bodies, lying in all directions, probably plant 

 remains or burrows, 2 feet. 



126^. A more or less discontinuous band of loosely 

 indurated ferruginous sand, filled with fossils, Yz foot. 



126*- Sand, yellow below, becoming gray above, the 

 upper 3 feet with much fine gravel included. The top 

 of the Wenonah "sand formation, the upper 3 feet pos- 

 sibly representing the Mount Laurel, 9 feet. 



126^. Dark, chocolate-colored, or nearly black green- 

 sand marl with no fossils, 10 feet. 



126^. Much lighter colored, gray, greensand marl, 

 no fossils observed, i foot. 



126''. Gray, glauconitic marl like that of the bed be- 

 loy, but containing an abundance of fossils. In the 

 lower portion of the bed the fossils are much less com- 

 mon, but they increase above until the upper i foot is a 

 mass of Gryphaea shells, 2^/^ feet. 



126*. Dark or nearly black greensand marl with no 

 fossils except an occasional Gryphaea near the base, ... 6 feet. 



126*. Lighter colored, gray marl to the top of the 

 bank. No fossils observed, 6 feet. 



Locality 126^. — This layer in the Wenonah sand, at Long- 

 street's marl pits, is one of the few localities of this formation 

 from which fossils have been secured. These fossils are all more 

 or less imperfect internal casts and moulds, and aside from the 

 species recognized in the following list, there are many others, 

 especially among the gastropods, which are too imperfectly pre- 

 served to be identified. Including these unidentified forms, the 

 entire fauna probably does not fall far short of 100 species. The 

 species which it has been possible to identify are as follows : 



AnThozoa. 



Micrabacia americana M. & H.
