THE MERCHANTVILLE. 45 



Locality ioi 2 . In the northern portion of the Cretaceous area 

 of the State, the most extensive Merchantville fauna has been 

 collected from an exposure in a small ravine, tributary to Cheese- 

 quake Creek. The head of this ravine is just north of the road 

 from Morristown to Jacksonville, about .75 of a mile west of 

 Morristown and a little over 2 miles northwest of Matawan-; it 

 is the most westerly and largest of three similar ravines along the 

 road west from Morristown, and the fossils were collected just 

 below the road. At this locality two distinct beds are exposed, 

 there being a dark clay below (loi 1 ), nearly or quite free from 

 glauconite, and a chocolate-brown, highly glauconitic clay-marl 

 bed above (ioi 2 ). The fauna listed below was collected entirely 

 from the higher bed.
