Spire moderately conic, terminating in an obtuse summit. Suture lightly marked. Whorls 4,5, convex, a little inflated, increasing regularly, the last whorl nearly as large as the spire and tapering to the base. Aperture subvertical, semioval, contracted by the presence of a single quite strong parietal fold. Peristome thick and of a brownish-corneous violaceous color. Outer margin slightly bent in. Length 1.5, greatest diam. 0.75 mm. (Crosse). New Caledonia: Paita, on the west coast (E. Marie). Pupa paitensis CROSSE, Journ. de Conch., xx, 1872, p. 227; xxii, 1874, p. 391, pl. 12, f. 5.-BOETTGER, Conchol. Mittheil., i, p. 63.-Vertigo paitensis CROSSE, J. de C., xlii, 1894, p. 304 (1896). This species evidently stands very close to C. kingi of Aus- tralia. It appears to differ in certain details, but I have not been able to compare specimens, and have copied the original figure.
