FAMILY HELICID.2Z — HELIX. 45 
This species has been found from Vermont to Georgia. In this State it has, I learn, also 
been found, but I am not aware of the precise locality. It occurs under pieces of wood, and 
among rotten leaves. I have not had an opportunity of examining it, and am indebted to Dr. 
Gould for the description and figure. It can only be confounded with the H. labyrinthica ; 
but its polished surface, and the absence of parallel ridges within its mouth, afford sufficiently 
distinctive characters.
