The fauna below the bone-bed is not so prolific as at the 
preceding localities. Gastropods and cephalopods are almost 
absent, while the lamellibranchs are represented by two species 
only. A good representation of corals is found, but brachio- 
pods fall short of their southern representation. Atrypas and 
Stropheodontas are most common. 
The fauna above the bone-bed closely resembles that at 
Delaware. The species which are most common at one locality 
are also the most abundant at the other. However, the faunas 
at the two localities are not identical, as a comparison of the 
species will show.
