OBSERVATIONS. 



I 



This shell is covered with a pale and very delicate 

 epidermis, and is distinctly gaping at each end. 



Mr. Say first discovered it on the southern coast, 

 and referred it with a mark of doubt to Psammohia. 

 I obtained a few valves near Cape Henry, on the 

 coast of Virginia, and in the collection of the Acad- 

 emy is a very perfect specimen, found by Dr. S. G. 

 Morton at Great Egg Harbour. In a fossil state, it 

 occurs in Virginia, but is not common.
