Shell 32.5 mm high and 25.7 mm wide. Colour yellowish-brown with three brown spiral bands on the last whorl. Protoconch pale brown, paucispiral, with 11/2 whorl, maximum diameter 1.0 mm, exposed height 0.9 mm. Transition to teleoconch well marked. Teleoconch with 4 7/8 strongly scalate whorls. Axial and spiral sculpture on early teleoconch whorl forms a finely latticed pattern; on later whorls the axial sculpture is more prominent. Sutural ramp wide, with some faint spiral lines. From 2nd teleoconch whorl on, the narrow axial ribs form sharp narrow lamellae when crossing over the sutural ramp; in younger whorls when well preserved, their upper parts are reflected abaperturally. The depressions between the lamellae are often coloured brown. Spiral sculpture consists of 10 spiral bands, narrower bands (one each) of second, third and fourth order are placed in between. Body-whorl with well defined siphonal fasciole. Aperture white, roughly triangular, with 9 lirae inside outer lip. Columella concave, with three folds, the anterior one forming the rim of the siphonal canal, which is curved abaxially. Columellar callus white, with rather strong granulations on the columellar lip and short spiral ridges on the parietal lip, and in frontal view partly covering the rather narrow umbilicus which is open till 65% of shell height but expanding strongly in the last whorl. A sinus in the outer lip at the shoulder of the last whorl is delimited by 3 teeth on the parietal lip and by a marked indentation in the outer lip.

Off Senegal, and off Gabon; 5-50 m.
Bathymetry: 5 to 50 m; one juvenile in sediment core at 150 m.
