Carychium mexicanum Pilsbry, 1891 Southern Thorn

    Near Florida Caverns State Park, Marianna, Jackson Co., Florida (average size is 1.75 mm.) Two Hundred eighty three specimens are pictured.

    Franklin D. Roosevelt (U. S. 32nd president), pictured above on the dime as a size comparison for the Carychium gaggle, had an elk, a cat, two lizards, a fish, an amphipod, and three mollusks named after him - the mollusks being:
Prunum roosevelti (Bartsch and Rehder, 1939) [as Marginella]
Terebra maculata roosevelti Bartsch and Rehder, 1939
Octopus roosevelti Stuart, 1941

    The enid landsnail, Cerastus roosevelti (Dall, 1910) [as Buliminus] was probably named for Theodore Roosevelt (the 26th president).
