(Original description by
W.H. Dall) The height of the shell attains 7 mm. The small, white shell has with four well rounded
whorls exclusive of the minute glassy nucleus, and a distinct not appressed
suture. The spiral
sculpture consists of a feeble thread at the base and two stronger, rather widely separated, sharper threads around the narrow
umbilicus. The spiral sculpture also consists of (on the last whorl about 25) obliquely retractive low folds which barely reach the periphery, with narrower interspaces, but are feebly and irregularly revived on the base, especially near the umbilicus. The subcircular
aperture is hardly interrupted by the body and has a sharp thin margin. ==Distribution==
