Pusia hendersoni
species of gastropod
Pusia hendersoni is a species of sea snail, a marine gastropod mollusk, in the family Costellariidae, the ribbed miters.
Description
The length of the shell is 17 mm; the length of the body whorl is 10 mm; and the maximum diameter is 6 mm.
(Original description) The shell is small, consisting of about seven whorls, excluding approximately three small, smooth, brownish whorls in the protoconch. Its color is whitish, with a brownish base that becomes darker near the periphery, where it appears as a narrow brown band just behind the suture on the spire.
The axial sculpture consists of (on the body whorl, about ten) rather sharp, nearly vertical ribs with wider interspaces, which become obsolete near the siphonal canal. The spiral sculpture consists of (on the penultimate whorl, about eight) rather feeble, flattish threads that are stronger and more widely spaced toward the canal, from which they are separated by a distinct sulcus. The siphonal canal bears two or three much stronger spiral threads.
The periostracum is pale and fibrous. The suture is distinct but not deep. The aperture is narrow; the outer lip is sharp and is lirate internally; the columella has three plaits; and the siphonal canal is moderately differentiated and slightly recurved.
This brief starts where responsible research should: with the source description of “Pusia hendersoni” as species of gastropod. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of gastropod. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q138824429. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
