A single, heavily worn shell found on Cabo Delgado .Previously recorded from the area near the type locality. There is also a single shell in the Natal Museum (L6653) collected on 19 February 1963 by A.C. and W.H. van Bruggen in the forest east of Gôndola in Central Mozambique . Characteristic strong corrugation (of the periostracum) can be observed only on fresh shells, and “a small, rather indistinct basal denticle situated well within and rather on the right-hand side of the shell” ( Preston 1912: 71) can be missing ( Pilsbry & Cooke 1920: 362, pl. 34, fig. 15). The shell from Cabo Delgado has just barely noticeable thickening in place of the lower palatal tooth, with a corresponding slight indentation on the outer surface of the last whorl. N. corrugata has a stronger corrugated periostracum and is proportionally higher than the preceding species .
