Helix alternata. Great numbers appeared in a garden under some vegetable 

 rubbish during rainy weather. 



Helix multitineata. All that I have found here are darker colored than those 

 from some other localities ; perhaps owing to the ferruginous character of the 

 swamp which they inhabit. 



H. tridentata. All I have yet met with more closely resemble the variety from 

 the northeastern states than those from the west, as exhibited by Binney in the 

 Boston Journal of Natural History. 



H. thyroida. Many hundred empty shells were found in a hollow .stump, ap- 

 parently brought there and stored up (when filled with the snail) by some little 

 animal. Many of the shells were indented as if by the teeth of the captor. 



Planorbes. The habitat of these appears to be comparatively still waters, as 

 ponds and mill races. Some of mine are quite one inch in diameter.
