Description The height of the shell attains 1 mm, its diameter 0.9 mm. The very small, white shell is umbilicate, turbinate, not nacreous, with a conic brownish spire. The first whorl appears to be smooth. On the second whorl fine radial folds or puckering appears below the suture, becoming coarser on the following whorl. The body whorl has six strong, smooth spiral keels, narrower than the intervals, which are flat and crossed by numerous retractively axial threads, which are much narrower than their intervals. Within the umbilicus, two rather small spiral cords are visible. The aperture is quite oblique and subcircular. The outer lip is strengthened by a rounded external rib or varix a short distance behind the edge.Pilsbry H.A. 1921. Marine mollusks of Hawaii, XIV-XV.
