Limicena nyasana (Smith, 1899)

Fig. 18 Buliminus (Conulinus) nyasanus: Smith 1899: 586 , pl. 33, figs 41, 42 (Nyika Plateau, Mount Chiradzulu and Zomba Plateau; 21× 15 mm).

A widespread but not very common species, with a general distribution from southern Tanzania to southern Zambia, Malawi (type localities) and Mozambique. Found at one station on Cabo Delgado. Differs from the three preceding species of Cerastidae by the wider bulimoid shell with a cylindrical umbilicus, and by the characteristic protoconch sculpture of seven strong spiral ridges well illustrated by Mordan (1998: 62, fig. 3) .
