Alaginella geminata

(Original description) The biconical shell is glossy, and solid, becoming opaque in maturity and thin and translucent in youth.

It comprises four whorls that are flattened above the shoulder and contracted at the base.

Upon maturity, the spire is covered with a callus sheet that obscures the sutures, while a thicker layer extends over the body whorl ahead of the aperture.

The aperture is narrow, subrostrate anteriorly, and channeled posteriorly, ascending the previous whorl.

The outer lip has a thick varix externally and approximately ten evenly spaced small denticles internally.
