aperture is nearly filled up by the teeth and the con- 
traction of the lip. If this variety were to be seen 
alone it would be adjudged to be a good species, and 
is generally so considered. Having examined a 
great number of every variety from numerous locali-

The animals do not differ in the least degree. 
 Hzuix fridentáta resembles Hexix palliata on its 
Upper surface, as has been mentioned in the remarks 
on that species, but differs from all others. The 
situation in which I have most commonly found it 
is under the layers cf wet and decaying leaves in 
forests; it is also found under flat stones. I have 
one specimen in which the direction of the whorls is 
reversed. ^ T S ie. H
