" Shell irregularly ovate, marbled with white and brownish red, 

 covered with a thin brown epidermis, which is coated for about 

 one third of the shell with the enamel-like glaze, which takes its 

 commencement near the pillar. The spire is deeply channelled and 

 carinated, exposing the subglandiform apex, and forming with the 

 subreflected sharp upper border of the body-whorl, a wide spiral 

 excavation. The upper edge of the outer lip recedes from the 

 spire. The pillar, winch is very much curved, has three plaits, 

 and is bordered on the basal half, with a rich chesnut longitudinal 

 band."
