In the East African lamarckii the dorsal spots are partially ocellated with purplish grey, whereas in the Indian redimita all dorsal spots are purely white, a few lateral ones excepted, which may enclose some chestnut marginal spots; besides, in the much larger lamarckii the dorsum is greyish fulvous instead of ochraceous to olivaceous, the aperture is less curved behind, the fossula is crossed by 3-5 (instead of 1-3) ribs, the fossular denticles are more accentuated, and the terminal ridge is less broad and never slit longitudinally.
