Description
editThe length of the shell varies between 5 mm and 15 mm, its diameter between 1 mm and 6 mm.
The shell is small, slender, tall, and moderately solid. Its color is white (possibly bleached). It comprises seven whorls, including a two-whorled exserted protoconch, and is angled at the suture.
The sculpture features small, sharp spiral threads, with three on the earlier whorls and about ten on the body whorl. Above, the threads are widely spaced, but they become crowded towards the base. The interstices are latticed by growth lines. The aperture is narrow and oblong, with a short siphonal canal.[2]
Distribution
editThis marine species is endemic to Australia and occurs off New South Wales, South Australia, Tasmania and Victoria.
