F++/Gem South Sudan. Unreal giant. This subspecies is very different from the specimens from Egypt. The shell is very heavy and has an unusual elongated shape with a well-defined rostrate of the anterior. The callus is very massive and high. The differences between these subspecies can be clearly seen if you put this next to the specimen from Egypt. This size is unique to the southern population, specimens of which are always smaller than those from the north. Payment in RMB are possible
