Ficus communis Roding Common Fig Shell Plate 9!

North Carolina to the Gulf of Mexico. The Bahamas.

3 to 4 inches in length, thin, rather fragile, and with spiral threads which are sometimes made reticulate by axial threads. Uncommon, except on the west coast of Florida where it is washed ashore in great numbers. No oper- culum present. Formerly known as Pyrula and Ficus papyratia Say, but the latter name is preceded by two earlier names, communis Roding 1798 and reticulata Lamarck 1816 (as well as 1822). Carol's Fig Shell (named after Mrs. Richard W. Foster), Ficus carolae Clench, is very rare, and is irregularly spotted with reddish brown on the inside of the shell. It was first discovered by Mr. Leo L. Burry of Sarasota off Key Largo, Florida, in 100 fathoms.
