Columella edentula, common name the toothless column snail, is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Truncatellinidae.
Description The 2.5-3 (-3.5) mm. shell is cylindrical with a conical apex and yellow-brown to brown. The aperture is without teeth and the simple lip is thin. The shell has (4.5 )5-6 (-7) whorls.
