Atlanta turriculata d'Orbigny, 1836
This species is easily identified by the feature for which it was named; the spire forms a tall turret-like structure and is the only species with this spire shape.
The spire is formed of 4¼ whorls and is a tall thin turret shape.
The spire is covered in numerous interrupted spiral lines and a tall ridge runs around the middle of each whorl.
The spire varies in colour from light purple to red and deep brown.
The adult shell is very small, reaching only 1.8 mm.
The keel is tall and transparent and inserts between the final and penultimate whorls in large specimens.
Eye type a, operculum type a, radula type I.
