Shell to 151 mm

This species is believed to be endemic to the Hawaiian Island chain in 3 to 116 m, the largest individuals having been found on Midway Island. However, three specimens. all dead collected from the Panama area, are in various United States museum collections.

Shell color white with 2 spiral rows of squarish brown spots, 3 on body whorl; outline of whorls flat with convex subsutural band; protoconch of 2 bulbous glassy whorls; subsutural band noded, followed by a second band, the two separated by a series of punctations which become interrupted lines on later whorls, the 2 bands occupying half the whorl in early whorls; axial sculpture absent; spiral sculpture of rows of punctations, the punctations coalescing into punctate spiral lines on extremely large individuals and the nodes becoming less prominent: body whorl smooth anterior to periphery except for axial striae; aperture semi-elongate; columella recurved, with moderate parietal callus on large specimens.

Most specimens under 40 mm have been collected in water from 20 m. or deeper, while most of the larger specimens have been found at a depth of about 6 m. or less, indicating that they probably breed in deep water. They are sometimes found living with T. areolata.
