Admete gracilior is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails.^[1]

Description

The length of the shell varies between 7 mm and 12 mm.

(Described as Admete rhyssa) The small, white shell has an olivaceous periostracum, a loosely coiled (decorticated) protoconch, and about four subsequent whorls separated by a distinct suture.

The axial sculpture of (on the body whorl a dozen) rather narrow, nearly vertical ribs, which extend from suture to suture on the spire and from the suture to the margin of the base in the body whorl, with wider interspaces. 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 coming to a node when they intersect them. The base of the shell is nearly smooth except for one or two minor threads near the siphonal canal.

The aperture is semilunate. The outer lip is thin, body with a thin layer of enamel. The columella shows three oblique plaits. The siphonal canal is shallow, short and contains a faint fasciole. ^[2]

Distribution

This species occurs in the Pacific Ocean from the Aleutians to California, USA
