Description
Size up to 15mm in length. (Described as Melarhaphe zelandiae)The shell is closely related to Austrolittorina unifasciata (Gray, 1826), but it is distinguished by having shorter and less convex whorls that are not as inflated. It is much darker in color, appearing uniformly blackish on the exterior and grayish-brown where the surface has been corroded; the inner part of the base is sometimes whitish. The interior is a rich, dark chocolate-brown, marked by a distinct white band below. The spiral sculpture is much better defined than in the Australian shells, particularly on the base, where the interstices are not linear and are rendered prominent by their white coloration. Additionally, the peripheral subangulation is more clearly marked.
