deserving state and/or federal protection; currently one cave 

 crayfish is considered a Species of Special Concern by the 

 State of Florida; and the Squirrel Chimney Cave Shrimp is 

 listed as Threatened under provisions of the U. S. Endangered 

 Species Act of 1973, as amended. 



Since 1894, naturalists have identified Florida springs, sinkholes, 

 and caves as habitats of plants and animals (Hubbard 1901; Lonn- 

 berg 1894, 1895; Faxon 1898; Hubbell 1936; Carr 1939; Hobbs 1940^, 

 1941, 1942fl, 19426; Young 1942, etc.). H. H. Hobbs, Jr. and H. B. 

 Sherman apparently were the first to attempt a systematic survey of 

 Florida's caves in order to enhance their studies of cave species (Hobbs 

 19426; Hobbs et al. 1977). Ferguson et al. (1947) followed with the 

 first catalogue of the springs of Florida, a work that was later updated 

 by Rosenau et al. (1977). In 1962, the Florida Speleological Society 

 published the first extensive inventory of caves of Florida and south 

 Georgia (Hippenmeier et al. 1962). This list included 188 caves in 

 Florida and south Georgia that could be entered using traditional caving 

 methods. The pioneering survey efforts of the Florida Speleological 

 Society also led to papers on the state's cave-associated vertebrates 

 (Pylka 1957) and aquatic troglobites (Pylka and Warren 1958, Warren 

 1961). The crayfish portion of Warren's 1961 list was updated by 

 Hobbs et al. (1977), Franz (1982), Franz and Lee (1982), Hobbs (1989), 

 and Franz and Franz (1990). Peck (1970) provided the first comprehensive 

 list of terrestrial arthropods from Florida, including the first records 

 of terrestrial troglobites from the state. Franz et al. (1971) presented 

 a list of gastropods from caves in the Marianna area of west Florida. 



Since 1968, many important biological discoveries in Florida 

 caves have led to the description of 11 new troglobitic taxa. Most of 

 these discoveries resulted directly from efforts of the cave diving 

 community, particularly divers associated with the Cave Diving Section 

 of the National Speleological Society and National Association of 

 Cave Divers. Aided by advances in SCUBA equipment, divers penetrated 

 many previously inaccessible underwater cave systems. These discoveries 

 have enhanced our ability to interpret better the factors that have led 

 to the development of the region's complex aquatic troglobitic faunas. 



This paper provides an updated list of the troglobitic species of 

 Florida and south Georgia. It summarizes distributional records for 

 both troglobitic and other cave-inhabiting species and comments on 

 the zoogeographic patterns exhibited by troglobitic species in the 

 region. The distributional patterns for cave crayfishes originally proposed 

 by Franz and Lee (1982) for the most part remain intact, i.e., (1)
