Shell stoutly fusiformly turreted, solid, whitish, tinged with chest- 

 nut at the base of the aperture ; whorls 7, rounded and somewhat 

 flattened above, longitudinally strongly nodulously ribbed, and sculp- 

 tured transversely with numerous fine thread-like striae ; aperture 

 subovate ; outer lip thickened, flattened, and variced externally, 

 dentate within ; canal short, slightly recurved ; jiosterior sinus 

 rather broadj above which there is a small chestnut-coloured spot. 



Alt. 4j, diam. 2 lines.

 sutures, and with three or four irregular dark-chestnut line-like spots 

 near the periphery of the last whorl and on the columella ; whorls 

 6, with about eight stout somewhat nodulous longitudinal ribs, 

 crossed by smaller transverse ridges that become larger at the back of 

 the outer lip and towards the base ; aperture narrowly ovate ; outer lip 

 flattened and variced externally, slightly sulcate within ; columella
