since 1942 and the first new troglobite since the descriptions of Crangonyx 

 grandimanus (Bousfield 1963) and Asellus parvus (Steeves 1964). 

 The discovery of the Miami Cave Crayfish set the stage for the disclosure 

 of four other crayfish discoveries in the 1970s. 



D. Bruce Means, who began visiting northwest Florida caves in 

 the mid-1960s, made numerous important collections of cave crayfishes 

 and vertebrates from caves and sinks in the Tallahassee and Marianna 

 areas. Means made several collections of a new crayfish at Gopher 

 Sink and Culley's Cave in 1970 and 1971, which he and Hobbs later 

 named Procambarus orcinus (Hobbs and Means 1972). Other collectors 

 who contributed specimens used in the type description of this crayfish 

 included H. R. H. Heineman (Clay Sink, 1956), J. Halusky (Gopher 

 Sink, 1970), J. Bishop (Osgood Sink, 1968), J. Couch (cave 3 miles 

 (4.8 km) south of Woodville, 1962), and L. B. Trott (Wakulla Springs, 

 1957). Specimens of a second new crayfish, collected first by Michael 

 N. Horst at Big Blue Spring on the Wacissa River in Jefferson County 

 in 1970, were described as Procambarus horsti in the same paper 

 with Procambarus orcinus (Hobbs and Means 1972). 



Barry Mansell and Frank Hurt collected the first specimens of a 

 new cave crayfish at Sim's Sink {Procambarus erythrops Relyea and 

 Sutton, 1975) in Suwannee County in 1971 (B. Mansell, personal 

 communication, Jacksonville, Florida); they also took specimens of 

 Troglocambarus maclanei from Sim's Sink, Procambarus lucifugus 

 from Bat Cave (Alachua County), Sweet Gum Cave, and Indian Cave 

 (Marion County), and Procambarus pallidus from Squirrel Chimney 

 in 1971-1972. Mansell and Bruce Sutton collected specimens of Haideo- 

 triton wallacei from Gerard's cave in 1969. Kenneth Relyea and Sutton's 

 explorations of north Florida caves were contemporary with those of 

 Means, Mansell, and Hurt. They collected additional material of Pro- 

 cambarus erythrops from Sim's Sink in 1971-1972; Procambarus pallidus 

 from Pallidus Sink, Squirrel Chimney, and Martin Cave in 1972; and 

 Troglocambarus maclanei from Sim's Sink in 1975. The new material, 

 plus those collected by Mansell and Hurt, from Sim's Sink allowed 

 Relyea and Sutton to describe Procambarus erythrops (Relyea and 

 Sutton 1975). Relyea also obtained two specimens of a unique crayfish 

 from Alexander Springs in Lake County in 1973 and 1974 (Relyea et 

 al. 1976) that later was described as Procambarus delicatus following 

 the collection of a third specimen in 1985 by J. B. Smith and D. 

 Haren H (Hobbs and Franz 1986). 



In 1973, Stephen R. Humphrey and Franz visited Orange Lake 

 Cave in Marion County for the first time after cavers reported large 

 numbers of bats present in the cave. Lee and Franz returned to this
