LAND SHELLS OF MONBOE CO., PENNSYLVANIA. 



BY H. A. PILSBRT. 



During September, 1909, I spent a couple of weeks at Bartons- 

 ville, Monroe Co., Pa., and employed some of my leisure in collect- 

 ing shells. The country rock is a shale of Hamilton age. The 

 shells were mostly taken on a steep, stony, wooded hillside facing 

 east, and in a pasture under stones. The species taken are for the 

 greater part common. See also Nautilus XXI, p. 67, where Mr. 

 Joshua Baily, Jr., lists Monroe County shells.
