Description

The length of the shell attains 5.7 mm, its diameter 2.5 mm.

(Original description) The small shell has an ovate-cylindrical shape and is rather gibbous. Its colour is white on the protoconch, and pale cream on the remainder of the shell. It contains 5 whorls of which two compose a rather elevate protoconch. Its sculpture shows on the first adult whorl are ten narrow, elevated, wide-spaced radials. These degenerate as growth advances; from the last suture they persist as downward dashes, and vanish on the anterior half of the shell. The entire surface carries dense microscopic spiral scratches. The aperture is narrow and vertical. The varix is prominent and expanded. Near the summit is excavated a broad and shallow sinus, and at two-thirds of its length occurs a stromboid insinuation A thin free edge reaches over the aperture. On the columella is a substantial callus. The siphonal canal is short, wide, and open.[2]

Distribution

This marine species is endemic to Australia and occurs off New South Wales.

gollark: You should probably have size and density things actually.
gollark: Okay, more: barn, farm, greenhouse, shed, museum, arena of some kind, city hall (or other governance building), embassy, post office, granary, bunker, missile launch facility, airport, taxi station, shipyard, and gym.
gollark: Okay then. Buildings which could exist: house, office, shop, mall, factory, mine, school, police station, SCP containment warehouse, regular warehouse, bus station, bus *stop* (sort of a building), underground train network stop, non-underground train network station, fire station, fire removal station, power plant, apiary, sewage treatment facility, garbage dump, garbage incinerator™, hospital, clinic (small hospital), plaza, park (sort of building), data center, hotel, prison, retirement home, theater, retirement home, restaurant, cafe, bowling alley, car wash, self-storage facility, seaport, car repair place, car dealership, bookshop, library, scientific laboratory, bank, substation, *nuclear* power plant, university, radio/TV/whatever transmitter, cell tower, [more coming].You should probably have a mechanic so you can have, say, apartment buildings composed of multiple "houses", but more generalized.

gollark: So, yes, you want me to think of buildings?
