Originally described from Destin, on the Gulf Coast of Florida, Solariorbis terminalis (Pilsbry & McGinty, 1946) is yet another member of the microgastropod family Tornidae found also along the coast of Southwest Florida. Larger shells of the species reach only 2.5 mm (about 0.1 inch). The shell has a low spire, the suture is well-defined, and the last whorl is rounded at the periphery (outer shell “edge”). The sculpture includes 4–5 spiral cords along the shell periphery. The aperture is rounded, and the umbilicus relatively narrow. Shell color is translucent-white. The shell illustrated was collected in 2008 by Lois Dunnam, near the Sanibel Fishing Pier. Photos by Patricia A. Starkey, original shell identification by Harry G. Lee.
