The shell is of moderate size for the genus (maximum length 20 mm) and broadly fusiform. The spire is high, consisting of five subangulate postnuclear whorls and a protoconch of undeter-mined nature. The suture is well-impressed. The body whorl is broadly fusiform and of moderate size. The aperture is moderately small and ovate, with little or no trace of an anal sulcus. The outer apertural lip is erect and marginally serrate or crenulate, the projections forming this edge reflecting the spiral sculpture of the shell surface, as do the crenulations on the inner surface of the outer lip. The columellar lip is erect, except at its posterior end, where it is adherent and forms a tiny callus. The siphonal canal is moderately short, barely open, and dorsally recurved at its tip.
The body whorl bears three broad, flangelike varices of broadly triangular cross section. Each varix is brief on the shoulder, most prominent at the shoulder margin and below, and extends to the point at which the canal bends sharply dorsally. Earlier whorls appear to have four varices, and the first few postnuclear whorls bear five or six varices. Each varix extends posteriorly over the shoulder and is appressed to the former whorl, thus forming a buttress that interrupts the continuity of the shoulder. Spiral sculpture consists of four major cords, one on the shoulder and three on the body; one or two minor cords are apparent above the major cord on the shoulder, and another one is apparent between the shouldermargin cord and the major cord anterior to it. The canal bears five to seven minor cords. Each of the major cords is divided into parts by incised lines on its crest and sides: the shouldermargin cord bears two such lines on its crest and one on its anterior flank; the shoulder cord bears two lines on its crest; the other two cords bear one or two lines in the same position. The leading edge of the last varix is densely fimbriate, the fimbriae arranged in a draped fashion between straight radial lines, (he lines not corresponding to the spiral sculptural elements on the outer (trailing) edge of the varix. Shell color is translucent blue-white, under a flat-white, lamellose intritacalx.
