The type locality for this species is the Warner Lakes beds in eastern Oregon.

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.

Sculpture is comparatively uniform in character, being composed of fine growth lines.

[1] In general the width of shell can reach up to 10 mm[1] and so this is the largest species of North American Valvata.
