Vol. 84, No. 47, pp. 411-420 29 February 1972 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW CRAYFISH OF THE SUBGENUS PUNCTICAMBARUS FROM THE SAVANNAH RIVER DRAINAGE WITH NOTES ON CAMBARUS (P.) REBURRUS PRINS {DEC APOD A, ASTACIDAE) Rudolph Prins^ and Horton H. Hobbs, Jr. Western Kentucky University, Bowling Green, Kentucky 42101 and Smithsonian Institution, Washington, D.C. 20560 The new crayfish described below represents the second member of the subgenus Puncticambarus known to inhabit headwater streams of the Savannah River. Prins (1968) de-scribed Camharus reburrus from a single tributary in Jackson County, North Carolina, and although he searched in other streams in the area, he was unable to find it elsewhere. Unknown to Prins, but about the same time, Gregory L. Dougherty collected specimens of C reburrus from several tributaries of the French Broad River in the vicinity of Black Mountain, Buncombe County, North Carolina. Furthermore, juvenile specimens that the junior author had tentatively as-signed to C. acuminatus Faxon, 1884, had been obtained from three additional localities in the French Broad drainage system. In view of the facts that C. reburrus seems to be widely dis-persed in the French Broad drainage and that the type-locality is the only one situated outside of it, it seems possible, if not probable, that the population described by Prins in the head-waters of the Savannah River is an introduced one. That the type-locality is on "a short tributary leading from an impound-ment (Sapphire Lake) . . ."
