The endemic North Carolina crayfish, C. reburrus, is distributed 

 throughout the upper French Broad, but appears to be absent from the 

 Pigeon (and probably Nolichucky) watersheds, and from the main 

 French Broad system northwest of Asheville. The other species of 

 this river basin are C. b. bartonii, C. longirostris, C. asperimanus, C. 

 dubius, C. robustus (Hobbs and Peters 1977:30), and C. sp. C. The 

 type locality of C. asperimanus is Flat Creek, Montreat, Buncombe 

 County (Faxon 1914:391). We collected many specimens of what may 

 be an undescribed Puncticambarus in three streams in Madison County, 

 but for now these are assigned to C. sp. C. Bouchard (1978:36) reported 

 a specimen of C. latimanus from the French Broad in North Carolina, 

 extralimital to any part of the known range of the species, but considered 

 it probably an introduction. 



Watauga River — The Watauga River rises in western Watauga 

 County west of Grandfather Mountain and flows north and west into 

 Tennessee. A southwestern tributary, the Elk River, heads in 

 northern Avery County. It is a minor independent subdrainage in 

 North Carolina, but joins the Watauga in Tennessee. The Watauga is 

 impounded just beyond North Carolina's borders,' but eventually 

 merges with the Holston River of the Tennessee River system. 



The crayfish fauna of the Watauga River basin in North Carolina 

 is not well known, but consists of C. b. bartonii, C. longirostris, C. 

 asperimanus, C. dubius, and C. robustus. 



New River — The two major western tributaries of New River — 

 North Fork New River and South Fork New River — head in Ashe and 

 Watauga counties, respectively. They flow northeast and merge at the 

 northern Ashe-Alleghany county line to form the New River just before 

 it enters Virginia. Eastern tributaries, Little River and Brush Creek, 

 rise in central and eastern Alleghany County, and flow northward 

 into Virginia to join the New River. The New River merges with the 

 Kanawha River near Charleston, West Virginia. 



Cambarus chasmodactylus and probably Orconectes sp. B are 

 endemic to the New-Kanawha system, and in North Carolina they are 

 limited to, and close associates in, fast-flowing tributaries of the 

 New River. Records for these common species in the eastern tributaries 

 in Alleghany County, however, are sparse. The other members of the 

 New River crayfish fauna in North Carolina are C. b. bartonii, C. 

 asperimanus (Watauga County), C. dubius, and C. robustus.

Savannah River — The Savannah River begins as fast-flowing 

 streams in deep ravines on the eastern slopes of the Blue Ridge 

 in southeastern Macon, southern Jackson, and southwestern
