Shell small to medium, cW 21.6-25.5 mm, cH 10.0-12.8 mm, thick, and flattened to sub-discoidal shape; detached-whorl length 3.0-7.5 mm. Apex acute; spire nearly flattened to slightly elevated. Whorls 4 to 5, convex, increasing regularly; suture wide and shallow; last whorl rounded and stout. Shell surface with irregular growth lines. Shell colour with brownish zigzag or blotch patterns; ventral side with paler colour patterns; narrow dark brown spiral band on periphery. Periostracum thick or thin, corneous, and transparent. Detached whorl very short (sometimes nearly absent) and slightly descending. Peristome circular and double; lip thickened, expanded, and multi-layered. Aperture opened sub-laterally. Breathing device incomplete tube-shaped and its tip sometimes attached to preceding whorl; outer lip forming a short and nearly closed tube; inner lip with deep incision. Operculum calcareous, cup-shaped, and multispiral (Fig.
