PROC. BIOL. SOC. WASH. 95(1), 1982, pp. 27-47 CHECKLIST OF THE FISHES OF THE CENTRAL AND NORTHERN APPALACHIAN MOUNTAINS Jay R. Stauffer, Jr., Brooks M. Burr, Charles H. Hocutt, and Robert E. Jenkins Abstract. — A table lists 398 forms and 5 intergrade populations in 28 families in an area on the Atlantic slope from the Susquehanna River south to the Peedee River, including Ohio River basin drainages from the Monongahela River in Penn-sylvania to the Tennessee River in Alabama and Tennessee. The central Appalachians harbor a diverse fish fauna that includes numerous endemics. Jenkins, Lachner, and Schwartz (1972), as part of a zoogeographic analysis of this ichthyofauna, provided a table that lists the fishes of the central Appalachians by river drainage and general habitat. This table has been extremely valuable to ichthyologists, fisheries scientists, and environmental consultants throughout the past decade. Numerous studies have substantially increased our knowledge of fish distri-bution throughout the central Appalachians (Hambrick et al. 1973, Hocutt and Hambrick 1973, Hocutt et al. 1973, Stauffer et al. 1975, Stauffer et al. 1976, Hocutt et al. 1978, Stauffer et al. 1978, Hendricks et al. 1979, Hocutt et al. 1979, Lee et al. 1980) and indicated that the original table should be updated. Moreover, it was thought that the addition of the Susquehanna, Licking, Green, and Ken-tucky rivers would enhance the usefulness of the faunal list. The list (Table 1) includes 398 forms and 5 intergrade populations in 28 families. It covers an area on the Atlantic Slope from the Susquehanna River (New York and Pennsylvania) south to the Peedee River (North Carolina and South Caroli-na). Ohio River basin drainages that are included extend from the Monongahela River in Pennsylvania south to the Tennessee River in Alabama and Tennessee. It should be noted that the list is conservative. If a question exists as to the current or historic presence of a species, it is not included. No attempt is made to distinguish species that were historically present in the drainage from those that currently occur. Trinomials are used only when the distribution of subspecies could be accurately determined. The authors appreciate the encouragement of Dr. E. Lachner, who recognized the need for a revision of the original faunal list.
