Stromboidea
Original Description of Struthiolaria minor by Marshall, 1917:
- "Shell small, 18 mm. by 10 mm., oblong in shape with a subtruncata base. Sculpture consisting of vertical costae and spiral grooves. Costae 16 in each whorl, extending almost from suture, and bent slightly backwards into a shallow crescent. Spiral threads sharp, 10 in the penultimate whorl, 8 in the whorl above it; the threads pass over the costae without any interruption. Body-whorl with a large shallow groove in the middle, thus forming two carinae; the costae stop at the upper end of this groove, but the spiral threads are continuous to the end of the canal. Spire of 5 whorls, each shouldered; suture impressed but not canaliculate. Aperture with a thick inner lip, callosity covering part of the base."
