The dextral or sinistral shell is ovate-oblong and subventricose. The shell has whorls. The shell is similar in form to '' Achatinella livida'', but the spire is less thickened and more pointed at the apex. The color is whitish with chestnut bands, and the apex is pale brown. The ground-color, in some specimens, is pale chestnut or ferruginous, banded with darker shades. Other specimens are pure white. The aperture is white. The suture is scarcely if at all margined by a groove. The height of the shell is 21.3 mm. The width of the shell is 11.8 mm.''Achatinella rosea''
