'''''Cyrillia linearis''''' is a [[species]] of [[sea snail]], a marine [[gastropod]] [[mollusk]] in the [[Family (taxonomy)|family]] [[Raphitomidae]].<ref name="WoRMS">MolluscaBase (2019). MolluscaBase. Cyrillia linearis (Montagu, 1803). Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1389226 on 2019-11-28</ref>

==Description== The shell is fusiform and [[turriculate]]. It has an elevated and acute [[Spire (mollusc)|spire]]. The twelve [[Whorl (mollusc)|whorl]]s are convex and longitudinally costated (twelve ribs on the [[body whorl]]). They are transversally sharply striated with 6-7 elevated lines, which run along the volutions. They are rather broader over the ribs and very sharp between them The outer [[Lip (gastropod)|lip]] is thickened on the outside with an obtuse [[Varix (mollusc)|varix]] or rib, but smooth within. The [[siphonal canal]] is short, rather broad and slightly inflected.<ref>Wood, Searles Valentine. A Monograph of the Crag Mollusca: With Descriptions of Shells from the Upper Tertiaries of the British Isles. Vol. 1. Johnson, 1848.</ref>

==Distribution== This marine species occurs in European waters from [[Norway]] to the [[Azores]]; in the Mediterranean Sea. Fossils were found in [[Pliocene]] strata in [[Italy]].
