Description

The shell of this species was originally described as follows: shell imperforate or rimate, fusiform, thick and strong, brownish-orange color, the whorl is brownish-brown. Ornamentation consists of strong longitudinal waves, rounded, equal to their intervals, 8 or 7 in number in the last whorl; these waves are traversed by quite strong spiral chords, which widen into transversely oblong low tubercles above the tops of the waves. Between these cords there are several spiral threads in most or all intervals. Whorls are convex, the last with concave contours below, produced, in a fairly long anterior canal. Aperture oval, brownish-orange inside; thick or beveled peristome, armed with six subequal teeth inside; angular columellar margin at origin of anterior canal, with a small transverse fold above angle; fairly straight and long channel for this genus. Length 21.5 mm, diameter 11 mm, length of aperture and canal 12 mm. [3]


Distribution

This species is distributed in the Southwest Atlantic along Southeast Brazil and Argentina.
