Parviturboides interruptus (C.B. Adams, 1850) is a member of the microgastropod family Tornidae with ample distribution in the Caribbean and Gulf of Mexico, and is found also along the coast of Southwest Florida. Larger shells of the species reach only about 1.5 mm (about 0.06 inch) in diameter. The shell has a raised spire, and is covered by strong, raised spiral cords, that may number as many as 15 in the last whorl. The umbilicus is present, but small. The shell color is translucent-white. The shell illustrated, a young specimen, was collected in December 2015 by Phyllis Sharp, at the East End of Sanibel Island.
