Description

The length of the shell attains 220 mm and perhaps more. [2]

The shell is large and spindle-shaped, with a high spire comprising approximately three-quarters of the total aperture length. The whorls are rounded but may feature a subtle shoulder adorned with low nodules. Its surface displays fine spiral threads, with some specimens exhibiting occasional stronger cords. The outer lip tapers sharply at the base, forming a relatively slender siphonal canal. The inner lip has a strong fold at the base of the siphonal canal, with one or two faint columellar pleats above. The parietal region is marked by a rounded, in-running ridge just below the outer lip's insertion. The interior of the outer lip is mostly smooth, though mature specimens often have a subterminal row of denticles behind a slightly flaring outer lip. [2]

The shell ranges in color from whitish to pale buff or orange-brown, with darker brown nodules. The periostracum varies from olive-brown to dark brown. The animal itself is orange-red. [2]

Distribution

This marine species is endemic to South Africa and occurs off the Agulhas Bank (Cape Agulhas to Port Grosvenor) at depths between 30 m and 250 m. [2]
