ii6 CRETACEOUS PALEONTOLOGY. 



Vertebrata. 



Shark's tooth. 



Enchodus (tooth). * 



Along the road leading up the hill south of Walnford, the 

 Mount Laurel sand and Navesink marl are exposed, the transi- 

 tion from the pure red or yellow sand to the sandy marl being 

 gradual. 



Locality 148^. — :The lower portion of the section at this locality 

 is a pure quartz sand, stained with iron to a bright orange or 

 yellow color. Eossils occur in these beds, but they are for the 

 most part poorly preserved, about the only species represented 

 being Ostrecfi fdcata Mort., and a small, convex Gryphaear-'i{k& 

 shell, all in the condition of casts. A little higher up the beds 

 gradualy become more glauconitic, but are much decomposed. 

 In addition to the species already mentioned, Plicatula urticosa 

 Mort., Paranomia scabra Mort., and Belemnitella americana have 

 been detected in this higher portion of the bed. These fossils 

 are distributed through 10 feet or more of strata. 



Locality 148^. — Lying above these beds already mentioned, 

 there is three feet, more or less, of ferruginous, sandy, highly 

 decomposed greensand marl, exposed in the gullies by the road 

 side near the top of the hill, which is abundantly fossiliferous. 

 There is, however, no sharp line between this bed and the sub- 

 jacent one. The fauna collected from this bed comprises the 

 following species : 



Brachiopoda. 



Terehratella plicata Say. 



Vermes. 



Hamuhis lineatus n. sp. 



PelEcypoda. 



Nemodon eufaulensis Gabb. 

 Cucullaca antrosa Mort. 

 Axinea suhaustralis (d'Orb.). 

 Pinna laqueata Con.
