Amastra cylindrica is a species of land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae.[2]
(Original description) The shell is dextral, elongately cylindrical, tapering to a pointed summit. It consists of seven slightly rounded whorls separated by a moderately distinct suture. The aperture is oblong-ovate, and the columella ends in a flexuous tooth. The shell's surface is marked by strong longitudinal striations. Its coloration is of a light horn tone, encircled by numerous narrow brown bands.[3]
