stained with the ferruginous salts they contain. In some places 

 these nodules project from the cliff, or are strewed along the 

 shore. This nodular bed has few fossils, and reposes on a green 

 arenaceous marl containing —

Melania. Melanopsis brevis. 



Cyclas. Neritina, n. sp. 



Scales of Lepidosteus and Gyrogonites [Char a medicaginula) are
