Description
[edit]The shell size varies between 2.5 mm and 7 mm. The white shell is solid, polished and with microscopic growth lines. The periphery is more or less distinctly keeled or angulated, with an impressed spiral line. There are eight, nearly flat whorls. The umbilicus is small and deep. The columellar tooth is strong and prominent. The interior of the outer lip is ridged, terminating in small tubercles within the mouth.[3]
(Description of Odostomia sicula) The white shell is solid and polished. Its length measures 6.25 mm. The eight whorls of the teleoconch are nearly flat. They are marked with microscopic growth lines. The periphery of the shell is more or less distinctly keeled or angulated. The shell shows an impressed spiral line. The small umbilicus goes deep. The columellar tooth is strong and prominent. The interior of the lip is ridged, terminating in small tubercles within the aperture.
G.W. Tryon (1889) considered it a synonym of Odostomia conoidea Brocchi.[4]
