Helix solitaria Say. This species is very scarce in the 

 eastern part of the state, but appears to be quite common in the 

 western portion. In the neighborhood of Ann Arbor it has 

 apparently died out entirely. Although dead, bleached specimens 

 are quite common, yet in several years collecting in that vicinity I 

 was unable to obtain a single living specimen, and other collectors 

 were equally unsuccessful. Several years ago Mv. A. B. Lyons of 

 Detroit, found a few living individuals in a single locality, some 

 of which are deposited in the museum of the Detroit Scientific 

 Association.
