Description

The white shell has a length of approximately 9 mm. The numerous whorls of the teleoconch are flattened, with scarcely a distinct suture. They are encircled by three spiral ribs, four on the body whorl, the lower part of which is smooth.[3]

Distribution

This species' distribution ranges from the northernmost existing specimens located within the Persian Gulf, Gulf of Oman and the Arabian Sea, to as far south as the South West Cape, Tasmania's southernmost point of land and off various coasts situated on the geographical exterior of the largest island in the world, Australia.

gollark: It's not *quite* 1984-level.
gollark: At least the US's handling of it makes me feel better about the UK.
gollark: What, several months beforehand?
gollark: What if it was a SECRET biolab in Spain operated by the Illuminati?
gollark: Well, that's... worrying in the longish term, then.
