Botelloides is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.[2]
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.
