SUMMARY — The troglobitic fauna is composed of three isopods, 

 two amphipods, one shrimp, 18 crayfishes (including two subspecies 

 and two intergrade populations), one snail, one spider, one spring- 

 tail, and one salamander. At least one species (Caecidotea hobbsi) 

 occurs in groundwater habitats outside of caves, per se; the amphipods 

 (Crangonyx hobbsi and Crangonyx grandimanus) also may use 

 similar habitats, particularly in light of their wide geographic dis- 

 tributions. Several taxa in this list remain undescribed, due to the 

 lack of critical material in collections. Faunas and assemblages are 

 described in the section entitled Obligate Cave Faunas and Karst 

 Regions.
