400:. There is great variation in the height of the spire and with its increase there is a proportionate decrease in the width of the umbilicus. The apical two whorls are flat and planulate, smooth and shining, unmarked with carinae even when the remainder of the shell may have three.

Dimensions of the holotype and paratypes are as follows: The width of the shell is 4.6-8.0 mm. The height of the shell is 2.6-5.4 mm. In general the width of shell can reach up to 10 mm and so this is the largest species of North
American

This species is characterized by its flat nuclear whorls and generally flat shell. Only rarely is the spire as elevated, while great numbers are as flat as the lowest. The thickness of the shells is greater than in any other
