The dorsal colour is usually paler than that of the three preceding species. The four dorsal bands are more prominent and wider than those of comptoni, and in most shells the central two join into one very wide band on top or on the right of the shell. The front and rear bands, which like the central pair are usually interrupted and not continuous, are in most shells clearly visible. The dorsum is sometimes spotted (piperate), and even occasionally reticulate, the colour of the marks being medium dark brown. The teeth in the region of the fossula are smaller than those of angustata, and more regular than those of comptoni) they are longitudinally depressed in the centre, the depression continuing to form a marked columellar sulcus running the whole length of the shell. The lower part of the fossular teeth sometimes bends out to form a marked protrusion into the shell. Occasional albino specimens have been found in most species of Notocypraea, but those of piperita usually bear at least a faint trace of bands on the columellar side of the dorsum.
