Distribution
This species is endemic to the Kiwi Seamount north of New Zealand.
Habitat
This top shell is found at depths of between 540 and 680 m.
Shell description
The shell is of medium size, solid, conical, with canaliculate sutures, imperforate, but there is a broad smooth concave basal area, bounded by a ridge. Sculpture consists of two prominent nodular spiral keels, and many weaker spirals, rendered granulose by growth lines. The operculum is oval, callused, with coarse spirals around the periphery, and with indistinct broad flat pustules over the central area.
Shell coloration is dull light brown, and the callus is nacreous.
