Description The length of the shell attains 9.3 mm, its diameter 4.1 mm.
(Described as Mitra microzonias) The shell shows a row of white spots so arranged as to come one on each rib, forming a chain on the centre of the body whorl.Sowerby, G. B. II. (1874). Monograph of the genus Mitra. In G. B. Sowerby II (ed.), Thesaurus conchyliorum, or monographs of genera of shells. Vol. 4 (31-32): 1–46, pls 352–379. London, privately published
(Described as Mitra glabra) The shell is oblong-ovate in shape, notably thick, and possesses a smooth, polished surface. It is longitudinally ribbed; these ribs are rounded in form, though they become obsolete on the body whorl. The columella is equipped with four distinct folds.
The shell is a ashy-brown, while the lower portion of the body whorl transitions into a chestnut-brown. Furthermore, the shell is encircled by a single, narrow, yellowish band.
