The shell is large (maximum length 110 mm) and broadly fusiform. The spire is moderately high and consists of seven weakly shouldered, postnuclear whorls and a protoconch of undetermined nature. The suture is strongly impressed. The body whorl is large and broad. The aperture is moderately large and widely ovate, with a posterior anal sulcus. The outer apertural lip is strongly dentate and bears a prominent labial tooth near the junction of the body and the siphonal canal. The columellar lip is adherent
above and slightly detached below. The siphonal canal is moderately long, moderately broad above, and tapering anteriorly to a narrow, tubelike, narrowly open distal portion.
The body whorl bears three varices, each ornamented with moderately long, slender, recurved foliated spines. Other axial sculpture consists of one or two short intervarical costae, these most prominent as tubercles in the shoulder region. Spiral sculpture consists of low spiral cords and minutely tuberculate threads. Where the spiral cords intersect the varices, the spines are developed. Two spines are persistent on the varices of the spire whorls and five are developed on each bodywhorl varix. The shoulder spine is longest and is upturned; the remaining four are progressively shorter anteriorly. Three spines are developed on the siphonal canal, the posteriorrnost one the longest, the remaining two progressively shorter. In addition, small, ventrally bent spinelets alternate with the major spines.
Shell color is light brown or tan, with darker brown on the elevated, tuberculate portions of the spiral elements.
