It contains 12 whorls, showing a moderately strong subsutural square-cut fold. The concave shoulder shows 5 to 9 spiral threads. It is strongly gemmate with about 24 gemmules on the penultimate whorl. The aperture with the siphonal canal measures almost half the total length. The interior of the aperture is white. The outer lip is narrow and slightly incised. The columella stands upright and is slightly askew. The siphonal canal is elongate, narrow and slightly recurved. [1]
