Amastra assimilis is a species of land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae.[1]
(Original description) The shell is conically elongate and sharply acute at the apex, consisting of seven rounded whorls with a well-defined, impressed suture. The aperture is small and ovate, while the columella is very short, plicate, and twisted. The outer lip is acute and slightly thickened internally.
The shell's color varies from white to salmon, with some specimens displaying a white lower half on the body whorl and a salmon upper half. The interior is pure white.[2]
