Description
The shell is generally globose with an open but narrow umbilicus, the surface commonly reticulate resulting from longitudinal lirae crossing transverse striae. The ventral lobe of the suture is rather narrow with a median saddle about or little less than half the height of entire lobe. The first lateral saddle is subangular to angular.
