Struthioptera

Stromboidea


Original Description of the genus Struthioptera by Finlay & Marwick, 1937, p. 61:

  • "Shell moderate to large, heavily built, spire subequal to aperture in height, whorls strongly tubercular at or below the middle. Body-whorl with a strong basal keel of 2 close ridges weakly but closely tubercular. Wing trapezoidal with thickened reflexed margins and a concave upper margin forming a deep, rounded sinus on the shoulder. Spur sharp but short, the outer margin descending steeply to meet a wide angulation at the end of the basal keel, then lightly curved backwards for an equal distance to meet the extremity of the pillar. The flat portion of the wing, viewed laterally, is oblique to the axis of the spire at an angle of about 30°."
