Shell description

Shell rather small, elongated fusiform, solid, with a moderately long canal. Sculpture consisting of subequal narrow spiral cords, about 10 on the penultimate whorl, the interspaces shallow, much broader than the cords upon the base, where they have a fine spiral thread; axial sculpture formed by numerous vertical broadly rounded ribs, 15 to 20 on the body whorl, where they become obsolete below the periphery. Colour light - yellowish, the spirals reddish - brown. Spire elevated conic, of the same height as the aperture with canal; outlines straight. Protoconch of 2 smooth whorls, small and globose. Whorls 8, regularly increasing, convex, very lightly shouldered, the last somewhat inflated; base excavated. Suture not much impressed. Aperture large, oval, broadly angled above, produced below into a fairly long oblique and open canal, rounded at the base. Outer lip convex, sharp, lightly lirate inside. Columella subvertical, slightly concave. Inner lip narrow, spreading over the parietal wall, narrowed below, and forming the inner edge of the canal. Operculum unknown.[3]

The shell height is up to 49.5 mm, and width up to 21 mm.[3]

gollark: My fusion plant thing only had 2 reactors, which easily covered the power needs of everything in existence several times over.
gollark: Also, the highest-end power transmission things I know only go up to 2GRF/t.
gollark: That sounds utterly awful for the server.
gollark: I've generally found that they work nicely at all isolation of things ever if you have power.
gollark: Well, presumably someone could put withers on the outside too.
