UPPER CRETACEOUS. 129
The next exposure, 14 mile below the preceding, at Corbits (Old
Union) Bridge, presents 5 feet of laminated materials essentially like

the preceding and furnishes a closely similar assemblage of forms. The
list follows:

 

; Araucaria bladenensis Berry. Malapoenna horrellensis Berry.
= Chondrophyllum Nordenskioldi Heer. Cephalotarospermum carolineanum
s Cunninghamites elegans (Corda) Endl. Berry.
Ba Kalmia brittoniana Hollick?

os Near Ivanhoe, 56% miles above Wilmington, left bank, the Black

; Creek species Chondrophyllum Nordenskioldi Heer was obtained in
close association with the following scarcely determinable pelecypod
casts, ete.: Leda sp., Pecten sp., Crassatellites sp., Cardiwm sp., un-
determined pelecypods, crab claws. (U. S. G. S. Locality No. 5363.)
The material containing these forms is similar to that at the two pre-
ceding localities.

One-eighth mile below the preceding, marine beds again make their
appearance, a section of which is given below:
