Description

The small shell is very solid, subcylindrical or claviform. The sculpture consists of nodose ribs that do not attain the suture, and fine spiral threads which are most dense at the summit of the whorl. There is no epidermis. The protoconch consists of two smooth and elevate whorls. The aperture is wide, without varix or internal armature. The outer lip is simple. The wide sinus is U-shaped, its right margin resting on a massive insertion callus. The fasciole is indistinguishable.[4]

Distribution

This marine genus occurs off Australia and New Zealand. One species is found in the Atlantic Ocean off St. Helena.

gollark: It can't be effective at that if people can just work around *it* when they want to.
gollark: Perfect robustness is probably not practical in human social infrastructure but it can at least be better.
gollark: You have to have ones which are better at producing good outcomes even if there is abuse.
gollark: You can't stop people from misusing systems. The entire point of courts and such is that people don't act in good faith all the time.
gollark: Not that anyone actually unironically uses them.
