Description

The shell grows to a length of 60 mm. The thick shell is subfusiform. The ground color of the shell is light green, with a reddish tone between the arcuate, opisthocline ribs and with a thick, olive-brown periostracum. The acuminate, orthoconic spire ends abruptly in a large blunt protoconch. The whorls are slightly convex. The outer lip shows a thick callus and parietal tubercle. The anal sinus in this species is very wide and rather shallow. The pear-shaped aperture is relatively large. The broad siphonal canal is unnotched and of moderate length. The subsutural cord is strong and more tumid than in Toxiclionella haliplex.[3][4]

Distribution

This marine species occurs along the Agulhas Bank, South Africa.
