(Original description in French) The shell is of the same size as Tritia semistriata but has a much more inflated, almost exactly ovoid outline. The spire is short, with rounded whorls separated by a well-marked sutural line. The body whorl is very developed, especially in diameter. The aperture is not very high, well-rounded, and the columella is short. The callus is very thick. ^[4]
