Description

edit

(Original description) The shell is rather small and thin, subdiscoidal, and flattened beneath, with a pale brown coloration. The epidermis is extremely thin, microscopically hirsute, or chagrined. The spire is slightly elevated and convex, consisting of nearly 4½ whorls that are scarcely convex. The aperture is large, and the outer lip is thin, sharp, moderately expanded, and reflected, featuring a deep curved incision below the columella, similar to that of Alcadia brownii palliata (C. B. Adams, 1849). The elongated columella is strongly margined on the inner side. [2]

Distribution

This species occurs in Jamaica.[1]
