Description
The general characteristics of the species in this genus are:
- the shell is subcylindrical and pupoid in shape
- the whorls wind obliquely on the last two-thirds of the shell
- sculpture: the earlier whorls are smooth, the later ones bear fine incised, spiral grooves
- the shape of the aperture is pyriform to circular
- the columella is excavate
- the outer lip is grooved within and bevelled to a sharp edge
Differences between the species are defined by the shell gradually widening towards the body whorl, or the shell not widening but is cylindrical.
Distribution
The species in this marine genus are endemic to Australia and occurs off New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia.
