throughout the system). The ubiquitous P. a. acutus may turn up in 

 the eastern reaches of the basin, and it is not inconceivable that 

 exhaustive effort could reveal C. carolinus along the border with 

 South Carolina. The latter species occurs in the upper Tyger River 

 watershed of the Broad-Congaree basin, in Greenville and Pickens 

 counties, South Carolina (Hobbs and Bouchard 1973:60-61). A juvenile 

 male crayfish (NCSM C-2229) that strongly resembles Cambarus 

 (Puncticambarus) spicatus Hobbs was collected in the North Pacolet 

 River of the lower Broad basin in Polk County, but it would be 

 premature to add this species to the North Carolina fauna on the basis 

 of this specimen. The species is known with certainty only from a 

 tributary of the Broad River in Fairfield and Richland counties, 

 South Carolina (Hobbs 1989:27). 



Catawba River — This heavily impounded system rises in North 

 Carolina, with its headwaters on the Blue Ridge escarpment in south- 

 eastern Avery, Caldwell, McDowell, and Burke counties. The streams 

 flow into and through the Piedmont Plateau. Tributaries that head in 

 southern Mecklenburg and western Union counties flow independently 

 south-southwest into South Carolina, where they join the Catawba 

 River in York County. The Catawba flows south into South Carolina, 

 where it enters the Wateree basin of the Santee drainage. 



Cambarus b. bartonii and C. asperimanus appear to be limited 

 to the foothills and upper Piedmont sections of the Catawba River 

 basin. The former may occur as far south and east as Catawba County 

 at the Alexander County line (Hobbs and Peters 1977:45-46), unless 

 the population there is revealed to be C. sp. A. Cambarus asperimanus 

 has been found in streams in Burke, Catawba, and McDowell counties. 

 Cambarus dubius has been reported from Avery County in the 

 upper Catawba basin (Hobbs and Peters 1977:24). Cambarus sp. 

 A and C. sp. C may occur throughout the system, and C. sp. B 

 currently is known only from Catawba County. Cambarus reduncus is 

 known from Gaston, Mecklenburg, and Union counties. Procambarus 

 a. acutus has been collected in Lincoln and Gaston counties. Hobbs 

 and Peters (1977:45) recorded Cambarus (Hiaticambarus) longulus 

 from a locality in the Catawba basin in northern Caldwell County, 

 but there is evidence that the specimens from that site either came 

 from a tributary of the nearby Yadkin-Pee Dee River, or belong to 

 what appears to be an undescribed species under investigation by 

 JEC. James (1966:13) did not show C. longulus in the Catawba basin, 

 and Hobbs later (1989:20) wrote that it ranges "south to the Yadkin 

 basin in North Carolina . . . ."
