Alcadia macilenta
Alcadia macilenta is a species of an operculate land snail, terrestrial gastropod mollusk in the family Helicinidae.
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. The elongated columella is strongly margined on the inner side.
Distribution
This species occurs in Jamaica.
