Description
editThe length of the shell reaches 60 mm. [2]
The shell is moderately small and narrowly spindle-shaped, becoming robust in adulthood. The spire whorls are adorned with strong, widely spaced, rounded axial ribs, which become less pronounced or nearly absent on the final adult whorl. The spiral sculpture consists of low, flat-topped cords separated by narrow, variably incised grooves. The siphonal canal is elongated with a narrow, slit-like opening. In mature specimens, the aperture features a pronounced callus nodule just below the outer lip's insertion, along with a well-developed varix behind the outer lip.
The shell is orange-brown when fresh, with axial ribs typically appearing slightly paler. The aperture is whitish, while the animal itself is orange-red. [2]
Distribution
editThis marine species is endemic to South Africa and occurs off the Agulhas Bank (Still Bay to Port Alfred) at depths between 50 m and 150 m. [2]
