C-1949), which has a tributary stream entering it from Singletary 

 Lake. Procambarus pearsei is known from as far north in the system 

 as northern Sampson County, and might occur in extreme southwestern 

 Johnston County. Its type locality, a pond and ditch on NC 22 south 

 of Fayetteville, Cumberland County (Creaser 1934:4), is in this river 

 basin. Procambarus blandingii, which occurs in the Lumber and Waccamaw 

 basins, appears to be absent from the lower Cape Fear, but this needs 

 investigation. 



The northern tributaries of the Northeast Cape Fear River originate 

 in the Coastal Plain in southern Wayne and northeastern Sampson 

 counties. The system drains almost all of Duplin, most of Pender, 

 western Onslow, and northern New Hanover counties. The Northeast 

 Cape Fear generally is considered an eastern trunk of the Cape Fear 

 River, but it flows into saline waters at Wilmington, independent of 

 the Cape Fear. As alluded to in the previous discussion of the Northeast 

 Cape Fear as a hydrologically and faunistically autonomous unit, there 

 are differences in the crayfish faunas of the two systems. Since the 

 Northeast Cape Fear is confined to the Coastal Plain, it is not surprising 

 that it does not harbor C. catagius or C. reduncus, both Piedmont 

 species. It does have P. plumimanus, however, which is absent from 

 the Cape Fear but present in the New (White Oak), and lacks P. 

 ancylus and P. pearsei, both of which occur in the Cape Fear, Lumber, 

 and Waccamaw. The rest of the crayfish fauna of the Northeast Cape 

 Fear is that of the coastal Cape Fear, i.e., C. latimanus, C. diogenes, 

 C. sp. C, F. fodiens, and P. a. acutus. 



New {White Oak) River — The major hydrologic units of the New 

 (White Oak) drainage basin are the autonomous New, White Oak, 

 Newport, and North rivers and their tributaries. All are small and all 

 empty into saline coastal waters behind barrier islands in Onslow 

 Bay, and Bogue and Back sounds. The New River drains the center of 

 Onslow County, and extreme eastern Pender and New Hanover 

 counties. The White Oak drains eastern Onslow County and forms 

 part of the boundary between southeastern Jones and eastern Onslow 

 counties. Included in the White Oak unit are Catfish and Great lakes 

 of Croatan National Forest, southwestern Craven County. The Newport 

 and New rivers both drain southern Carteret County, and both, like 

 the White Oak, are artificially connected with the lower Neuse River 

 basin to the north (see the P. plumimanus account). 



The crayfish fauna of the New (White Oak) basin consists of 

 C. diogenes, C. latimanus, F. fodiens, P. a. acutus, P. plumimanus, 

 and probably C. sp. C.
