Breadth, female, two-fiftLs — male, tliree-tehths 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 them 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 diifers in 

 being umbilicated. 



SuccrxEA CAMPESTRis. — 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 oi'cilis is very 

 great ; it diifers, however, in being less elongated, and of a more 

 robust form ; the revolution of the spire is much less oblique, the 

 sliell itself is thicker and less fragile.
