Clionella aglaophanes is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.

The longitudinal sculpture shows the whorls crossed from suture to suture by low, sharpish, subangulately projecting, dextrally convex, hardly oblique ribs, which run continuously, but are slightly diminishing in number, up the spire, there being about 15 on the last and 11 on the first regular whorl.

The spiral sculpture shows below the sinus-area a very slight angular projection of the whorls, which is made more marked by a thickening and elevation of the ribs at this point.

At the top of each whorl and close to the suture lies a small flattened thread, rising into minute longitudinal nodules at the ribs.

The fine suture is well marked, being a little impressed and defined by the slight swelling round the top of the inferior whorl.

It runs straight across the body to the base of the short, thick columella, down which it proceeds direct and parallel to the slightly prominent callus-edge on the left.

This is an extremely peculiar little shell, remarkable in its narrow cylindrical and compact form, its sculpture, and its slight silvery sheen, from which last feature its name is derived.
