Admete gracilior
species of mollusc

Admete gracilior, common name the slender admete, is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails.
Description
The length of the shell varies between 7 mm and 12 mm.
(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 axial sculpture consists of (on the body whorl a dozen) rather narrow, nearly vertical ribs, which extend from suture to suture along the spire and from the suture to the margin of the base in the body whorl, with wider spaces between. The incremental lines are rather marked. 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.
The aperture has a semilunate shape. The outer lip is thin. The body of the shell is covered with a thin layer of enamel.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Admete gracilior”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q3142147. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
