Anachis costellata is a species of sea snail in the family Columbellidae, the dove snails.{{WRMS species|511437|Anachis costellata |15 June 2025}}
The variety Anachis costellata var. pachyderma P. P. Carpenter, 1857 is a synonym of Anachis scalarina (G. B. Sowerby I, 1832)
Description
The length of the shell attains 15 mm.
(Described by P.P. Carpenter) The Mazatlán shells divide themselves with tolerable accuracy into two sets: the one is characterized by a coarse lamellar epidermis, while the other has one that is very thin, smooth, or rarely scaly, closely adherent, and displays the rich chestnut color of the shell. They differ from Anachis scalarina in their very much smaller size, chestnut markings, flattened whorls, and the adherence of the epidermis.
Distinguishing Features: Should the epidermal differences prove constant, they may be the best characters to recognize the species, as the features recorded by Sowerby I are subject to great variation. The decussation of the interspaces is generally only seen on the spire in the young shell; the spiral striae at the base are sufficiently conspicuous.{{cite book |last1=Carpenter |first1=P.P. |title=Catalogue of the collection of Mazatlan Mollusca in the British Museum collected by Frederick Reigen. |date=1857 |publisher=British Museum |location=London |page=527|url=https://www.biodiversitylibrary.org/item/61252 |access-date=15 June 2025}} {{source-attribution}}
