These shells (image, left) are indistinguishable from topotypes of Daedalochila auriculata (Say, 1818) (see: D. auriculata page two) from St. Johns Co., 150 miles to the east! Furthermore, self-collected specimens in my collection from Duval, Clay, St. Johns, Flagler, Putnam, Alachua, Volusia, Brevard, Seminole, Osceola, Lake, Orange, Marion, Polk, Hernando, Sumter, Levy, Dixie and Lafayette Cos. are essentially identical to all of these. On the other hand. the pallor of the animal (images below) contrasts sharply; see D. auriculata page three and D. auriculata live specimen . This lack of pigmentation may be an adaption to extreme sun-exposure; see D. uvulifera (Shuttleworth, 1852) Peninsula Liptooth page two and D. uvulifera page three for a parallel phenomenon in that species. As with all living material taken on this expedition during the second week in August, 2007, relaxed snails were placed in 70% ethanol for dissection and other animals were promptly placed in 95% ethanol for molecular systematics work at the Florida Museum of Natural History. |
