Achatina immaculata: Lamarck 1822: 128 View in CoL (height c. 152 mm).

A common, widespread eastern African species. Found at five stations inland and at one station on Cabo Delgado. Differs from all other species in the area by its large size (shell up to 200× 120 mm). Fresh shells differ from the similar most common A. fulica Bowdich, 1822 View in CoL (not found in north-eastern Mozambique so far) by the pink columellar margin. Juvenile shells are even more common and can easily be separated from all other shells in the region by the large smooth protoconch.
