Shell of the Week: The Florida Vitrinella
Vitrinella floridana Pilsbry & McGinty, 1946 is a very small species of the family Tornidae, that barely reaches 2 mm (about 0.8 inch) in diameter. The shell is smooth, totaling only about 3.5 whorls, with an open umbilicus, and the callus is absent. The shell is compressed, with the apex projecting only slightly, the whorl profile rounded, and the aperture oblique. The shell color in the Florida Vitrinella is translucent-white. The shell illustrated was collected in 2002 by Lois Dunnam at Gulf Side City Park on Sanibel.
