Popis

The shell is moderately small (maximum length 55 mm) and fusiform. The spire is moderately high, consisting of seven convex postnuclear whorls and a protoconch of undetermined nature. The suture is impressed. The body whorl is moderately small and fusiform. The aperture is broadly ovate, with a small anal sulcus, this reinforced parietally by a major and a minor spiral ridge. The outer apertural lip bears several fine lirae immediately below the anal sulcus, and is erect and finely dentate, the teeth becoming lirae extending into the aperture. The columellar lip is erect and marginally denticulate, the size of the denticles diminishing anteriorly; the last three or four denticles follow an oblique line from the lip margin to a point deeper in the aperture. The siphonal canal is long, arched to the left, and distally recurved.
The body whorl bears three low, foliaceous varices. Other axial sculpture consists of a large intervarical ridge, nodose at the shoulder to the right and a smaller ridge, not nodose, to the left. Spiral sculpture consists of numerous finely scabrous spiral threads. A small number of these threads are more prominent; where these intersect the varices, short to moderately long foliose spines are developed. On the upper portion of the body, four small, weak, tightly bunched spines are developed. Below this on the body are two moderately long, open spines. A moderately broad space separates the body spines from the two or three moderately long, open, somewhat recurved, canal spines.
Shell color is pinkish-orange, strongest on the varices and the intervarical ridges, paler on the spire. The apertural margin is bright red-violet.
