GASTEROPODA. HELICID. 81 
Animal cinereous, sometimes tessellated with pale-blackish. 
Eyes black. 
Ena montana was first discovered by Montagu, in woods, 
round Lackham, and in Bow Wood, in Wiltshire. It has since 
been found, by Mr. J. Miller, in woods near Bristol, in con- 
siderable plenty. 
On the Continent this species is almost confined to elevated 
regions.

This species is found beneath stones and dead leaves. It 
sometimes occurs on the trunks of trees after continued rain. 
It is common under the Salisbury Craigs; and in Rivelstone 
Wood, near Edinburgh ; in the woods round Bristol; and at 
Torquay, in Devon. I observed it once near the Eagle’s Nest 
Rock, on the Lake of Killarney. Montagu found it in abun- 
dance on the summit of the hill, in Portland Island, under 
stones.
