Agladrillia benjamini

(Original description) The elongate-conic shell is flesh-colored, with a protoconch that contains more than one smooth whorl.

In addition to the axial ribs, the whorls are adorned with numerous slender spiral threads.

The body whorl, just before the periphery, is marked by 27 spiral cords that are about equal in size and spacing, becoming only slightly stronger on the columella.

The aperture has a strong, deep sinus at its posterior angle, making the outer lip, anterior to this, distinctly claw-like.

The outer lip is strongly reinforced internally by a callus that has about 15 denticulations on its inner surface.
