The length of the shell attains 4 mm, its diameter 2 mm. (Original description) The shell is small and notably wider than that of †
Atys gracilis Dall, 1896. It differs from the latter species by possessing a lateral profile that is evenly curved, ensuring that no indication of an equatorial swelling is visible. Furthermore, the
aperture is proportionately wider and less produced behind, while the inner
lip above the
spire is more strongly twisted. At the spire, there is a shallow pit but no perforation, nor is there any thickened, striated rim present at the margin of the pit. Although the spiral grooving is similarly distributed, it appears rather sharper than in
A. gracilis. Additionally, the
columella is less obviously twisted; it is obliquely truncate and narrow, and it features a narrow but obvious groove located behind it. ==Distribution==
