Shell colossal, average height 76.72 mm, average width 34.58 mm. Very solid, conical-tapering, dimorphic in coiling direction, sutures smooth, columellar straight, rimaconcealed, aperture somewhat flabellate; periostome white, expanded and reflected.

Mostly purple; protoconch lacks coloration; middle and lower parts of body whorls dilated, upper part of whorls inclining and lighter-tinted; one broad but relatively shallow spiral channel
occurs on the middle of the whorls – although this channel is weak on the holotype compared to the paratypes it is readily recognized on the last half whorl.

The channel and the sloping upper part of the whorls emphasize the space between them, forming a ridge; filmy corneous periostracum covers the exterior surface below the ridge.
