Breadth, female, two-fifths — male, three-tenths of an inch. In- 
habits Georgia and East Florida. Cabinet of the Academy. A 
very common shell in many parts of Georgia, particularly the sea 
islands, also in East Florida. We found them numerous under 
the ruins of old Port Picolata on the St. John River, and on the 
Oyster-Shell Hammocks, near the sea, and in other situations 
under decaying palmetto logs, roots, &c. 
These shells would have been referred by Linne to the genus 
Helix, but as that genus has been limited by Mr. Lamark and 
others, to those shells of which the apertures are broader than 
long, I cannot with propriety, in the present state of Conchology, 
consider them as of that genus. Neither can I refer th«m to 
either of the genera which have been separated from Helix by 
Messrs. Lamark, Montfort, &c., by the characters which those 
naturalists have given of their genera. They differ from the others 
in having the pillar-lip elevated considerably above the surface of 
the penultimate whorl, so as to be equally prominent with the 
outer lip, with which it forms an uninterrupted continuation, and 
by the concavities beneath the lips, formed by the protrusion of a 
portion of the shell into the aperture. In this last character it 
approaches the genus Caprinus of Mr. Montfort, but differs in 
being umbilicated. 
SucciNEA CA5IPESTRIS. — Shell oval, very fragile ; whorls three, 
not remarkably oblique, pale yellowish, with opaque, white, and 
vitreous lines, irregularly alternating. 
Length not quite three-fifths, breadth seven-twentieths of an inch. 
This shell is extremely common in many parts of the Southern 
States ; it abounds in the sea islands of Georgia in the low, 
marshy grounds behind the sand-hills of the coast, where they are 
destroyed in great numbers by the annual conflagration of the old 
grass. On Amelia Island, East Florida, I found them in great 
plenty on the highest sandy ground of the island. On Cumber- 
land Island, in Mr. Shaw’s garden, I obtained several specimens 
from the leaves of radishes. 
The resemblance between this species and the ovalis is very 
great ; it differs, however, in being less elongated, and of a more 
robust form ; the revolution of the spire is much less oblique, the 
shell itself is thicker and less fragile. 
Animal whitish ; eyes, inferior tentacula, and a line passing
