Admete gracilior, common name the slender admete, is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails.

(Described as Admete rhyssa) The small, white shell features an olive-colored outer layer called the periostracum, a loosely coiled (decorticated) protoconch, followed by approximately four distinct whorls separated by a distinct suture.

The spiral sculpture consists of (on the spire four, on the body whorl eight) prominent threads with wider interspaces, overriding the ribs and forming nodes where they intersect them.

The base of the shell is nearly smooth except for one or two minor threads near the siphonal canal.

[2] This species occurs in the Pacific Ocean from the Aleutians to California, USA; also off Tierra del Fuego, Argentina and in the Ross Sea, Antarctica.
