Shell thin to moderately thick, aperture with thin to slightly thickened peristome. Operculum with prominent to weak pegs, sometimes absent in two species. Head-foot with cephalic tentacles only slightly longer than snout.
Female genital system unusual in having two equal sized sperm sacs (a bursa copulatrix and 'seminal receptacle') with their ducts emerging from their dorsal sides. Penis with swollen, unpigmented base bearing prominent concentric creases; distal two thirds smooth and tapering to point, often pigmented and muscular.
