The Giant Frog shell is a creamy white shell with brown spots and stripes along its entire surface. The aperture is white. The body whorl of this shell has a swollen hollow interior and a fairly tall spire. Two varices lie on the side of each whorl and there are six to eight knobs between varices. There is a short siphonal canal, but there are no teeth on the outer lip.
