Shell minute, oval, rather solid, rimate, smooth, and somewhat shining. Sculpture consisting of fine oblique growth-lines. Colour pale horny. Spire short, conical, of about the same height as the aperture ; outlines slightly convex. Protoconch small, smooth, and polished. Whorls 1,5, first slowly, then more rapidly increasing, moderately convex, the last subangled for a short distance in front of the suture ; base rounded. Suture deep, slightly channelled. Aperture oblique, semilunar, angled above. Peristome discontinuous, slightly thickened, sharp, somewhat expanded at the base. Columella very short, arcuate, rounded. Inner lip very little produced over the narrow umbilical chink, spreading as a distinct white callosity over the parietal wall. Operculum unknown.
Diameter, 1,25 mm. ; height, 2 mm. (type). Diameter, 1,7 mm.; height, 2,3 mm. (specimen in my collection).
Hab.—Waipipi, Manukau, type (W. H. Webster).
Remark.—The type specimen has the last whorl much more flattened at the periphery. The description and figure are after a specimen obtained from Mr. Webster.

Shell small, 1.75 to almost 3 mm in height, moderately elevated-turbiniform, imperforate, with about 5 smooth, evenly convex whorls, an impressed suture, and a very fine line at some distance below the suture; light yellowish brown to moderate orange in color; aperture rather broadly ovate, outer lip evenly arcuate, thickened and somewhat effuse at columella and covering the narrow umbilical perforation. Width 1.85 mm; height 2.94 mm
An analysis of the measurements of about 25 specimens from both northern New Zealand (Rangitoto Island, Auckland Harbour) and Easter Island shows that although the specimens from Easter Island appear to reach a larger size, there is a wide area of overlap and the height/width measurements fall in a virtually straight line. I can find no differences in form and general appearance between specimens from the three localities cited above.

RANGE.—Northern New Zealand, Kermadec Islands, and Easter Island.
