Shell small, ovate-lanceolate, turreted on the upper whorls. Colour 

 buff, with chocolate stains on the pillai' and canal. Whorls seven, 

 including the piotoconch, which consists of a minute rounded up-standing 

 initial whorl, followed by two smooth whorls with a median keel. 

 Sculpture: — The upper and lower whorls have diverse patterns of sculp- 

 ture; in the first adult, that is the fourth whorl, there is a flat sloping 

 shouldei', margined by a sharp and prominent keel ; anterior to the keel 

 the whorl is vertical, and carries two spiral threads ; under the keel 

 spring faint radial riblets that vanish before they traverse the whorl. On 

 the last wlioil the contour changes from pagodifoim to ovate, with a faint 

 shouldei' angle ; below the sutui-e run foui' tine close spiral thrends.
