H. THVKOiDES, Say. Very rare. I found on Wyoming Hills 20 

 or more dead shells, in good condition. They appeared 

 to have hibernated together and the spot became dry 

 during the winter and they all died. I have not found 

 them elsewhere, nor in this locality alive. 



H. CLAUSA, Say. Rare here; abundant near DesMoincs with 

 all'olaluis. It seems to avoid the islands and seeks damp 

 ravines. It is a fine little shell. 



H. PROFUNDA, Say. Rare here in Iowa. Nearly opposite this city 

 in Illinois at one place called Gooseberry Point, I found a 

 few specimens. It is found with clausa near DesMoines 

 but rather scarce. A white van frequently occurs. 



H. PULCHELLA, MiiU. Not here alive: fossil in Loess in this city. 



LiMAX CAMPESTRis, Binney. Abundant under boards in gardens, 

 in woods ; everywhere in dam.p places where protected 



from file sun. 



CiONELLA SUECVLINDRICA, Linn. Abundant on R.R. embanknient 

 one mile N. of Muscatine; have found it nowhere else. It 

 seems to live just below the surface of a sandy loam under 

 vines. 



Pupa pentodon, Say. Under damp and decaying leaves by old 

 logs in woods. 



P. FALLAX, Say. Abundant in one small region. I have found it 

 in a space not more than 10 feet square, by a slight 

 exposure of sandstone in a very damp spot about the roots 

 of a small stump, just on the border of a little prairie. It 

 seems to be entirely confined to this spot, 



P. armifera, Say. Abundant and widely dispersed; prefers 

 sandy loam among grass roots, near old logs in woods. I 

 have not seen it on river bottoms or on islands. Fossil in 

 Loess in this city.
