Shell of the Week: The Vera Cruz Caecum
The last of the Caecum series: another neglected local species of the family Caecidae, Caecum circumvolutum de Folin, 1867 has a tubular shell that rarely reaches beyond 2 mm (about 0.08 inch). The shell sculpture in this species shows a number of circular, very delicate grooves. The shell “plug” is pointy, asymmetrical. The shell color is white. The shell illustrated was collected by Dale V. Stingley in May 1954, on Sanibel.
