THE MERCHANTVILLE. 47 



Several other localities in the northern portion of the Creta- 

 ceous area have yielded small collections of Merchantville fossils, 

 but in no case has so' extensive a fauna been secured as at locality 

 loi^, just described. 



Locality 102^. The National Fireproofing Company has 

 made extensive excavations in the Woodbury clay at Lorillard, 

 east of Keyport, the clay used in the works being- removed down 

 to the top of the underlying Merchantville formation. The con- 

 tact between the twO' formations is recognized at once in the ex- 

 cavation at this point, the lower formation being abundantly glau- 

 conitic, while the higher formation is quite free from greensand. 

 In connection with the excavation at this locality, the work being 

 done with a steam; shovel, it is at times necessary to* dig a shal- 

 low pit in the subjacent Merchantville formation, in order to 

 furnish suction for the pumps, and at such times fossils from 

 this lower formation can be secured. During the period of the 

 writers visits to these pits, only a single opportunity was afforded 

 to secure collections from this underlying bed (j02^), and only 

 the following meager fauna was obtained: 



PeIyEK;ypoda. 



Cucullaea antrosa Mort. 

 Nemo area cretacea Con. 

 Cardium sp. 



Gastropoda. 



Turritella sp. 



Vertebrata. 



Fish vertebra. 



Extensive exposures of the Merchantville clay-marl may be 

 seen along the west bank of Matawan Creek, north of the town 

 of Matawan, the works of the Pennsylvania Clay Company being 

 located at this point. The pits wliich furnish the raw material for 

 the plant of this company, as well as other pits situated a little 

 'further north and no longer operated, afford an excellent section 

 of the Merchantville formation resting upon the subjacait Ma-
