Original Description:

Testa anguste et vix pervie umbilicata, depresso-globosa, cenfertim costulato-striata, olivaceo-cornea, lardeo-nitens; spira obtusa, convexa; anfr. 5 1/2, convexiusculi, ultimus antice vix deflexus, ad aperturam constrictus; apertura lunaris, tridentata: dente mediocri linguiformi in pariete aperturali paululum intrante; persist. reflexum, intus callo albo tenui labiatum, margine dextro dente parvo paululum immerso, basali dente marginali munito.
Diam. maj. 13, min. 11; Alt. 6 mill.
Syn. Helix tridentata var. Binn. in Bost. Horn. 3, p. 382, tab. 18, f. 2.
" " Fer. Hist. tab. 51, f. 3, fig. parva ad sinistram.
Hab. Prope Hopetown, Georgia, copiosissime.
Obs. Differt ab H. fallaci, umbilico angustiori vix pervio, colore saturatiore, peristomate minus incrassato et dentibus inter se magis remotis. Huc forsan pertinet figura Chemn. ed. 2. t. 64, f. 7-9 ad H. fallacem laudata. Variat quoad dimensiones; specimina duplo fere minora occurrunt.
Roughly translated: : "The shell is narrowly and hardly accessible to the umbilicus, depressed-globose, densely ribbed-striated, olivaceous-horny, sgreasy shine; spiral obtuse, convex; anfr. 5 1/2, arching right, the last one scarcely bent anteriorly, constricted at the opening; aperture lunate, tridentate: a medium-sized lingual tooth entering the apertural wall a little; it persists reflexed, lipped inside with a thin white callus, the right edge slightly immersed in a small tooth, the basal margin protected by a tooth.
Diam. maj. 13, min. 11; Alt. 6 million
Syn. Helix tridentata var. Binn. in Boston Horn. 3, p. 382, tab. 18, f. 2.
" " Hist. tab. 51, f. 3, fig. small to the left
Hab. Near Hopetown, Georgia, very abundant.
Obs. It differs from H. fallacius in having a narrower umbilicus that is barely accessible, a more saturated color, a less thickened peristome, and teeth more distant from each other. Perhaps the figure of Chemn. ed. 2. t. 64, f. 7-9 praised to H. deceitful. It varies as to its dimensions; specimens occur nearly twice as small."
