Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. R. Saul and W. P. Popenoe 1993 | Medium-sized, broadly fusiform buccinids having plumply convex whorls; suture sinuous, impressed. Spiral ornamentation of alternate width ribs; collabral sculpture of strong, nearly straight ribs strongest at pe- riphery and dying out before the suture and the siphonal neck. Aperture eye-shaped, rounded posteriorly, attenu- ated and gently twisted anteriorly; siphonal canal narrow, moderately long; columella strongly twisted; siphonal neck bearing a narrow false umbilicus bounded by a low but well-marked fasciole; inner lip smooth, overlain by thin callus, concave in its parietal portion, gently sinuous in its columellar position; outer lip thin, lirate within | |
| R. L. Squires and L. R. Saul 2003 | Medium to large shell, broadly fusiform, convex whorls, ramp can be concave and with parasigmoidal growth lines, suture sinuous and can be covered by swollen collar; periphery angulate, spiral sculpture of alternate-width ribs, collabral sculpture of ribs strongest at periphery and becoming obsolete anteriorly before suture or before siphonal neck, aperture elliptical with or without posterior notch, siphonal canal narrow and moderately long, siphonal canal twisted and bearing narrow false umbilicus bounded by a low but well-marked siphonal fasciole, outer lip thin and Urate within, columella smooth and with thin callus. |
