Shell thin, delicate, pearly white, acute, with nine rapidly enlarging whorls, roundly inflated (especially the last), which gives a turreted appearance to the spire; nucleus minute, glassy, smooth, simple ; nuclear whorls not separated by any sudden change of character from the rest of the shell ; general sculpture consisting of numerous close-set (three or four to a millimeter) narrow plications extending from near the suture obliquely and flexuously across the whorls, in general correspondence with the lines of growth ; on the last whorl fading away anteriorly and barely visible at the periphery ; lines of growth generally pretty distinct ; the whole shell covered with fine, somewhat wavy, spiral grooves and intervening threads, not strong enough to give a rough appearance to the surface, and evenly distributed (twelve to sixteen in a millimeter); aperture large, semilunate ; outer lip thin, simple, much arched and produced at the middle, and rounding broadly to the anterior end of the pillar ; columella with a slight callus, obliquely trimmed to a point, and slightly recurved anteriorly; notch obsolete, forming no distinct band, though indicated by the lines of growth and by a slight flattening of the whorl just in front of the distinct and well-marked suture, as in Daphnella. Lon. of shell, 10.25; of last whorl, 6.25; of aperture, 4.75. Max. lat. of shell, 4.25; of aperture, 2.0 mm. Defl. about 36°.
