Description. Shell rather small, subglobose. Whorls five, slightly rounded, and covered 
with numerous short rigid hairs. Suture distinct. Aperture very narrow, almost closed by 
an elongated lamelliform tooth on the pillar-lip, which extends nearly from the middle 
of the base to the junction of the outer lip with the body-whorl. Lip much depressed and 
reflected back on the outer whorl, and nearly incorporated with it, with a deep fissure near 
the centre of the inner margin. Often a small tooth-like projection about the centre of the 
margin of the outer lip. 
Color. Epidermis brownish. Animal whitish ; head and tentacles slate-colored. 
Diameter of shell, 0°3. 
This species is common in this State, and is very abundant throughout the Western States. 
In cabinet specimens, it is often found divested of its hairy epidermis. It can scarcely be 
confounded with any other species. 
HELIX ELEVATA.

H. elevata. Binney, Jour. Nat. Hist. Vol. 1, p. 191, pl. 19. 
Description. Shell large, convex, elevated, almost conical. Whorls nearly seven, some- 
what convex, with minute oblique strie. Lip reflected, more broadly so towards its lower 
inner margin, which is somewhat thickened. Umbilicus none. Pillar-lip with a stout white 
obliquely curved tooth. 
Color. Yellowish horn ; reflected edge of the lip and the tooth white. Animal ash-brown 
above. 
Diameter of the shell, 0°9. Height, 0°6. 
This species, which is rather common in the Western States, has likewise been observed 
in Pennsylvania. I have not succeeded in detecting it in this State, but it will probably be 
found in the western district.
