Gulella perissodonta ( Sturany, 1898)

Fig. 36

Ennea perissodonta: Sturany 1898: 1898 : 26, pl. 1, fig. 18 (Delagoa Bay, Mozambique; 4.2× 2.1 mm).

Found at one station on Cabo Delgado. Two shells (2.7× 1.4 mm) were collected by van Hoepen (van Bruggen 2006: 124) on Ilha Vumba only 49 km south of station 7 on Cabo Delgado. Prior to that, perissodonta was known only from south-eastern Mozambique, Swaziland and north-eastern KwaZulu-Natal where it is quite common. The type, described from the area near Maputo, is larger than illustrated here, but the shells from northern KwaZulu-Natal vary from 3.2×1.7 to 6.2× 2.5 mm (van Bruggen 1969: 47) .
