Summary: Total species = 51 (12 aquatic, 39 terrestrial); endemics = 24. 
the Appalachian Plateau on the western side of the valley. A total of 
394 caves are recorded, many of which are extensive and among the 
largest in the study area. Karst terrane is especially well developed, and 
the center of the valley, from Jonesville, Va., to Tazewell, Tenn., is the larg- 
est continuous karst corridor in the study area. The regional cavernico- 
lous fauna contains 44 cave-limited species; 41 are troglobites, and 27 
are endemic to the basin (Table 1 1). 
Patterns of Distribution 
We have recognized three general types of distributional patterns 
exhibited by cave-limited species of the study area. Ranges may be (1) 
very widespread, (2) trans-Appalachian, or (3) Appalachian Valley. Most
