Shell small and slender. Colour uniform cinnamon-brown except a patch of dark chocolate on the columella. Whorls fifteen. Protoconch five whorled, the later three bicarinate, crossed obliquely by numerous tine bars which bead the carinae. The adult whorls are beset with two bead-ridges, carrying each about sixteen gem mules of equal size to a whorl, vertically the gemmules run slightly oblique, between each ridge is a deep and narrow groove. In the antipenultimate whorl a thread appears in this groove and ultimately grows on the last whorl to a gemmule row. A raised thread beneath the suture ascends for a few whorls. The last whorl is ornamented by this thread followed by a row of large gemmules, two rows of smaller ones, an incipient peripheral row and two minor, basal, subnodulose ridges. The gemmules are coloured, polished, hemispherical, truncated and shelved above, and stand nearly their diameter apart on the ridge.
The suture is deep and well delined. Between the gemmules the surface is roughened by minute spiral threads cut by oblique growth lines. Aperture vertical, nearly square. Outer lip crossing the pillar in a spur. Anal notch a simple open fold. Canal short and briefly recurved. Length 4, breadth 1 mm. Shallow water in the Funafuti lagoon, several specimens.
