which is placed obliquely on the penultimate whorl, near the middle of the mouth; lips almost equaly [equally] prominent, continued; umbilicus moderate, not exibiting [exhibiting] the volutions, no grove [groove] on the ultimate whorl within it. Breadth 1/4 of an inch

Inhabits Florida (Jour. A.N.S. Vol. 1. p277.)

Animal longer than the breadth of the shell, acute behind above granula ^ ted, and blackish, beneath and each side white.

This we found in the orange groves of Mr. Fatio, on the river St. John, East Florida; it is usually covered with a black, earthy coat, which is probably probably collected and detained by the hairs When unincumbered with

this vesture, the shell is of a horn color. It is by no means so comon [common] as the preceding species.

3 P. Septemvolva. Shell much de= pressed discoidal, spire not prominent, whorls 7, perfectly lateral, compressed, depressed and marked with conspicuous lines and grooves above, a projecting carina on the upper edge of the body whorl, beneath which the lines and gr^ooves are obsolete; aperture subreniform, not contracted; lips equal, elevated, outer one reflected, regularly rounded so as to describe two thirds of a circle, pillar lip projectig inwards into an angle or tooth which is concave beneath; beneath,

the 4 exterior volutions equally prom= inent, traverse diameters equal to those of the upper surface; umbilicus central, moderate, attenuated to the apex so as to exibit [exhibit] the remaining volutions. Breadth, female 2/5; male 3/10 of an inch.

Inhabits Georgia & E. Florida (Jour. A.N.S. Vol 1 p278.

A very common shell in many parts of Georgia, particularly the sea-islands also in E. Florida. We found them numer= ous under the ruins of Old Fort Picolata on the St. John's river, and on the Oister= shell Hammocks near the sea and in other situations under decaying Palmetto logs, roots &c.

These shells would have been

referred by Linné to the Genus Helix, but as that genus has been limited by Mr. Lamarck, and others, to those shells of which the aperture are broader than long I cannot 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. Lamarck, Montfort &c. by the characters which those naturalists have given to their genera. They differ from others in having the pillar ip el= evated considerably above the surface of the penultimate whorl, so as to be equally prominent with the outer lip, with which it forms an uninter^rupted continuation, and by the cavities beneath

14

the lips, formed by the protrusion of a por= tion of the shell into the aperture. In this last character it approaches the genus Caprinus of Mr. Montfort, but differs in being umbilicated.

GENUS OLIGYRA

Shell rounded; aperture longer than broad semiorbicular, emarginated by the projection of the penultimate whorl; external lip reflected; pillar lip with obsolete calcareous deposit; umbilicus none; columella slightly angulated at the base

Animal terrestrial, operculated; tentacula 2, filliform, eys [eyes] prominent, placed at the external base of the tentacula; rostrum bilabiated at tip
