Cautor sp. cf. intermissa (Laseron, 1958b). Length, 2.5 mm; diameter, 1 mm. Shell: obese to conic; with two beaded spirals on each whorl; straw with patches of brown between the granules. Spire: protoconch dome-shaped, of two and one-half white whorls, the apical partly immersed, the two abapical whorls with prominent axial ribs; teleoconch of about thirteen slightly inflated whorls; suture narrow. Sculpture: two spirals of hemispherical beads on each whorl, three on the last whorl, the apical row larger than the abapical row, the granules regularly arranged in axial columns. Aperture: subquadrate; posterior canal a notch; anterior canal tubular, recurved. Color: yellow with chocolate brown between the granules, apex white. These triphorids are common in beach drift and found in sediments to depths of 10 m.
C. intermissa was described from Queensland and occurs in the Strait of Malacca, Philippines, and Loyalty Islands, and in Miocene and Holocene sediments in the Marshall Islands and Fiji (Ladd, 1972). The Hawaiian shells differ from the Australian shells in the number of whorls of the protoconch, which Laseron described as a single, tilted dome-shaped whorl, partly immersed in the summit.
