[edit] Distribution
This species of triton is endemic to southeastern Australia and the north east coast of the North Island of New Zealand.
[edit] Habitat
It is found from low tide level down to depths of 20 m.
[edit] Shell description
The shell is rather small and solid, with a conical spire, capacious body whorl, but small aperture ending in a recurved canal of moderate length. The inner lip is free edged, and smooth, except for a parietal tubercle. Sculpture consists of distant varices, and strong blunt axials, not reaching either suture. The whole surface is crowded with fine, flat-topped, slightly granulose spiral lirae.
The shell coloration is pale yellowish-brown, under a greenish-olive periostracum.
The height is up to 46 mm, and the width is 25 mm.
