Columella columella is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Truncatellinidae, the vertigo snails and allies. [2] This species is not listed in the IUCN red list and not evaluated (NE) [3] Subspecies Columella columella alticola (Ingersoll, 1875)
The columella is strongly four-plaited. The aperture is relatively narrow, and the outer lip is only slightly thickened. The shell exhibits a pale rose-orange coloration, adorned with two faint bands. Densely distributed throughout the shell are sharply waved, fine chestnut-red lines.
The base is of a lighter tint, the outer 6 cinguli of a rose pink, minutely dotted with creamy white. The columella and umbilicus are white, bordered outside with green, which tints the inner two basal cinguli, and curls around the columella into the throat. The inner edge of the outer lip is golden-brown and white, interior shining and nacreous.
The basal margin is decidedly expanded and curved. The columella is very oblique, concave and toward the insertion, its edge scarcely reflexed, simple, bearing a single triangular projection or tooth below the middle, and terminating in a very strong, quadrate, biplicate tooth at its base. The parietal wall is wrinkled.
