Description The shell grows to a height of 2.5 mm. The shell has a delicate yellow color with coarse and very conspicuous granulation of the surface. When seen in profile, they appear like little spines. It has about three well-rounded, rather loosely coiled whorls, forming an elevated spire with relatively large, prominent nuclear whorl and a very large body whorl. The well-marked suture is rather deep. The deep umbilicus is relatively large and has rounded walls. The peritreme of the aperture is slightly attached at the suture.Bush, K. J. 1897.
