Locality ■12'j. — Edg'ar Schanck's marl pit is situated a little 

 less than Yz mile southwest from that of Henry Conover, and 

 about 1.5 miles northwest of Holmdel. The bank from which 

 marl has been dug is about 16 feet in height, and was largely- 

 covered with talus at the time it was visited by the writer. Ex- 

 amples of Gryphaea convexa and Ostrea mesenterica are abundant 

 in the disintegrated marl of the talus slope. By digging through 

 the disintegrated material it was found that the fossiliferous zone 

 is apparently restricted to a thickness of about three feet near the 

 mid-height of the entire exposure. In the lower portion of this 

 zone the fossils are somewhat sparsely scattered through the marl, 

 and the large Gryphaea shells are inconspicuous, but in the upper 

 part these shells become more abundant; and at the very top of 

 the zone there occurs a conspicuous shell bed about one foot in 

 thickness made up almost exclusively of the shells of Gryphaea 

 convexa. The entire fauna collected at this locality is as follows : 



Brachiopoda. 



Terehratella pHcata Say. 



PELECYPODA. 



Cucnllaea neglecta Gabb. 

 Ostrea mesenterica Mort. 

 Gryphaea convexa Mort. 

 Bxogyra costata Say.
