THE WENONAH. 95 



130 2 . Dark clay below, with more or less glauconite, 

 the line of separation between this bed and the one be- 

 low being ill-defined, but within 2. feet of the base the 

 clay content has gradually disappeared and the bed is 

 nearly pure greensand marl. Near the base of the bed 

 the typical Navesink species, Belemnitella americana, 



makes its appearance, although it is not abundant, ... 6 feet. 



130 3 . Greensand marl with numerous specimens of 

 BjPOgyra costata and a smaller number of individuals 



of GrypJiaea convex and Belemnitella annericana, .... 2. feet. 



I3<D 4 . Greensand marl with fossils less conspicuous 

 than in the bed below, the white shells not being exposed 

 upon the surface of the cliff, 4 feet 



I30 5 . Greensand marl, crowded full of the shells of 

 Gryphaea convexa, . .,. i foot. 



I3<D 6 . Nearly pure, dark, greensand marl below, be- 

 coming lighter in color above and mixed with yellowish 

 or reddish sand, and gradually changing to the more 

 typical beds of the Red Bank sand at the top of the 

 bank, 20 feet. 



Locality /jo 1 . The lowermost bed in the above section, is at 

 the summit of the Wenonah sand, this passes up into the Nave- 

 sink marl, and at the very top of the bank is the base of the 

 Red Bank sand. This locality abounds in fossils, and is within 

 about a quarter of a mile from the locality which furnished a 

 number of specimens for Whitfield, which are recorded in his 

 monograph as coming from "micaceous clay under the Lower 

 Green Sand at pits. of Rev. G. C. Schanck, near Marlborough, 

 New Jersey." The horizon is undoubtedly the same at the two 

 localities, and all of the new species described by Whitfield from 

 this "micaceous clay" have been detected in the more recent col- 

 lections of the Survey. The fauna is a large one and the fol- 

 lowing species have been identified :
