Scotland, and Hoke counties. Some of the streams drain directly into 

 the Little Pee Dee River just across the South Carolina line. Eastern 

 tributaries rise in western Bladen and Columbus counties. The Lumber 

 River flows primarily east and south into South Carolina, where it 

 joins the Little Pee Dee River on the Marion-Horry county line south 

 of Nichols. 



The crayfish fauna of the Lumber basin consists of C. diogenes, 

 C. sp. C, F. fodiens, P. a. acutus, Procambarus (Ortmannicus) 

 ancylus Hobbs, Procambarus {Ortmannicus) blandingii (Harlan), and 

 P. pearsei. A locality for the latter species, given as "CAPE FEAR 

 BASIN. Bladen County: (2) 3.7 mi (6 km) S Dublin on St Rte 41" 

 (Hobbs and Peters 1977:52), actually is in the Lumber River basin. 

 An unidentified Procambarus, currently represented in collections 

 by only juveniles and one female, has been found in the Lumber 

 River basin in Robeson and Scotland counties. When form I 

 males become available, this species may prove to be Procambarus 

 (Ortmannicus) lepidodactylus Hobbs, which is known from the system 

 in South Carolina, or an undescribed species of the Pictus Group 

 currently known only from the Waccamaw River basin (see below). 



Waccamaw River — The northernmost headwaters of the 

 Waccamaw River drain southcentral Bladen and northern Columbus 

 counties, and its eastern tributaries drain western and northern 

 Brunswick County. Some of the northern tributaries enter Lake 

 Waccamaw, the largest of the natural Carolina Bay lakes, and the 

 Waccamaw River flows from the south shore of the lake. East of the 

 lake there is an extensive system of man-made drainage canals that 

 "connects Honey Island Swamp (Juniper Creek tributary) with Dans 

 Creek of the Cape Fear drainage and Big Creek which drains into 

 Lake Waccamaw, . . . ." (Shute et al. 1981:21). South of the lake, 

 the Waccamaw River forms part of the line between western 

 Brunswick and southeastern Columbus counties, then flows 

 southwest into South Carolina and enters Winyah Bay. The Shallotte, 

 Lockwood Folly, and Calabash rivers, which drain most of southern 

 Brunswick County, are here included in this system. The Calabash 

 River flows west into Little River in Horry County, South Carolina, 

 and is connected to the Waccamaw River through the Intracoastal 

 Waterway. 



The crayfish fauna of the Waccamaw basin consists of C. 

 diogenes, C. latimanus (known from two localities in Brunswick 

 County), F. fodiens, P. a. acutus, P. ancylus, P. blandingii, and P. 

 pearsei. Specimens from this basin previously assigned to P. 

 lepidodactylus actually represent a new species being described by
