Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. A. Olsson and R. E. Petit 1964 | Shell large, oblong-subovate, with a moderately high, convex dorsum and a flattened base, the ventral face of the outer lip and body whorl together lying nearly in the same, flat plane, their lateral margins subangulated to weakly rounded. Aperture is intermediate between that of S. earolinensis and S. prohleinatica, narrow and strongly curved to the left above, wider in the anterior one-quarter section, and in front of that deeply impressed on both sides over the siphonal canal. The labial margin of the outer lip is sharply lirated throughout, the lirae on the parietal side longer and narrower. Fossula distinct, excavated, with a strong, bounding ridge within. The posterior canal is a deep, half-circle sulcus, hollowed out within above the buried apex with a high sharp rim elevated prominently above it on the left or body whorl side. Siphonal canal notch deep, rounded, pinched in at the entrance and sharply rimmed. Surface of the dorsum shows longitudinal growth lines in the middle zone covered by a glaze of enamel on the sides. |
