Descrição:

(Pilsbry, 1896): “shell with ample, well-like umbilicus, long-conic; thin but rather solid; opaque, white or flesh-tinted; smooth except for slight growth-lines usually indistinctly crimped in spiral order, shining. Spire attenuated above, the earlier whorls smooth, corneous, mamillar; sutures slightly plicated. Whorls 7, slightly convex but somewhat flattened at the periphery; regularly widening, the last not deflexed, narrowed toward the base, forming a narrowly rounded ridge around the very large umbilicus, which penetrates well-like to the apex. Aperture small, oblique, narrowly oblong; peristome white, subcontinuous, in contact with the body-whorl only for an extremely short distance above; outer and basal lips narrowly expanded, columellar lip straighter, dilated.”
