Natural History of the 



species, but of the fifth I can find no account, and it may be new.- 

 These two must, therefore, remain unnoticed for the present.

Figs. 2 and 3. — Helix Alholahris (Say.) {The White Lipped 

 Helix) Montreal Mountain, 24th April, 1867. 



In the above two figures the largest and most common species 

 is represented, and the following is the description given in 

 Gould's Invertebrata of Massachusetts. 



'• Shell orbicular, depressed-conical, thin, shining, of a yellow- 

 ish brown or russet-colour ; whorls five or six, rounded, separated 

 by a well defined suture, and forming a moderately elevated spire, 

 regularly and distinctly wrinkled by the lines of growth, which 

 are crossed by very numerous, delicate, revolving hair lines, 

 scarcely visible without a magnifier ; aperture, semi-elliptical, 

 contracted by the lip, which is white and very broadly reflected ; 

 outer edge sharp, somewhat waved, and coloured orange on the 

 back ; umbilicus covered by the extremity of the lip. Diameter 

 generally over one inch. 



" The animal varies in color, sometimes being pure white, 



cream-colour or greyish ; head brownish above ; tentacula dusky 



" at tip ; eyes black ; back shagreened with granular tubercles ; 



foot rather more than twice the diameter of the shell, pointed 



behind." 



This is one of the most abundant of the few species of snails 

 found in Canada. In all newly cleared lands the whitened shells 

 of dead specimens are everywhere to be met with and living ones 

 may be procured by searching under decaying logs, rotten stumps 

 or stones. Limestone cliffs overgrown with small trees and herb- 

 age are more especially favoured haunts of this species. Dr. 

 Gould remarks : 



" This is our largest snail, and, though so simple in its structure 

 and coloring, is a pleasing shell. Its delicately striated surface,
