| L. R. Saul and R. L. Squires 2008 | Shell fusiform, of medium to large size with long flexed anterior canal; ramp sloping, set off from whorl by sculpture or by weak to moderate angulation, bordered posteriorly by spirally ribbed collar, on spire ramp crossed by strong, raised, imbricate growth fines that join posterior edge of parietal callus shield. Protoconch small. Sculpture of more or less definite, rounded axial ribs, strongest near shoulder, fading anteriorly and overridden by narrow spiral cords; spiral cords commonly forming spirally elongate nodes on axial ribs; earliest whorls with strong distant axial costae and weaker spiral lines. Aperture elongate, outer lip commonly a little reflexed, especially posteriorly; inner lip callus well developed; parietal callus shield present, commonly expanded posteriorly across previous suture; three oblique columellar folds approximately medially placed on columella. |
