Southwest Florida Shells with Emphasis on Sanibel & Captiva

By José H. Leal

Family Tornidae

Teinostoma cryptospira

(A.E. Verrill, 1884)

Hidden-spire Vitrinella

At 2 mm (0.08 inch) maximum size, Teinostoma lerema Pilsbry & McGinty, 1945 is one of the smallest members of the family Tornidae in Florida. The suture (line where two successive whorls join) in this species is not very visible, not forming a distinct line on the shell surface. The shell surface is smooth, the aperture rounded, and the base shows a callus partially covering the umbilicus. The color is translucent milky-white. The shell in the photos was damaged during growth, with a “nick” evident on the last whorl. It was collected in 2008 by Lois Dunnan, near the Sanibel Fishing Pier. (This entry was originally erroneously listed as the Trifle Vitrinella, Teinostoma lerema Pilsbry & McGinty, 1945.) Shell identification by Harry G. Lee, and photos by James F. Kelly.
