Shell small, fusiform. Whorls five, with about twelve longitudinal rounded 
ribs which are crossed on the body whorl by 8 or 10 spiral ribs, the grooves 
between which are transversely striated, by growth lamin. Aperture oval, the 
outer lip grooved inside; canal short and straight. Length 7mm.; breadth 4mm.

from Terra del Fuego.
