Type species: Melania turritella Dunker, 1846 (= Cerithium subturritella Orbigny, 1850 nom. nov.), original designation; Hettangian, Germany.
Included species: Cerithium subturritella d’Orbigny, 1850 , Hettangian; Tangarilda sp. sensu Gründel 2010, Hettangian.
Emended diagnosis.—A genus of the Mathildidae with three primary spiral ribs. The middle and sometimes also the abapical spiral rib are stronger than the others (whorls octagonal in transverse section). The growth lines are asymmetrically opisthocyrt with the backmost point between the adapical and the middle spiral rib. The lowermost part of the growth lines is strongly opisthocline. Secondary spiral ribs may be developed.
Stratigraphic and geographic range.—Hettangian (and Sinemurian?); Germany.
