FAMILY HELICID^ 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 locahty. It occurs under pieces of wood, and 

 among rotten leaves. I have not liad an opportunity of examining it, and am indebted to Dr. 

 Gould for the description and figure. It can only be confounded with the //. lahyrinthica ; 

 but its polished surface, and the absence of parallel ridges within its mouth, afford sufficiently 

 distinctive cliaractcrs.
