This is tentatively identified here, because the specimens do not completely match photos of the type lots. This is one of several Zafra species that has a very wide shell, and thus looks rather globular. The shell in these specimens is glossy, and mostly or often completely white, sometimes with wavy brown axial lines on the base and two vague unpigmented to straw-coloured or tan spiral bands. The shell is 3 to 3.5 mm long, with 3 to 3.5 teleoconch whorls. There is a relatively weak subsutural groove, and the aperture edge is regularly denticulate, with a ridge of denticles on the parietal wall. The protoconch is white, with 3 whorls and a weak midline cord.
