( Lampetra aepyptera, Notropis bifrenatus, Etheostoma vitreum, Percina peltata 
nevisense ) have southern termini in the Coastal Plain drainages. Noturus 
funosus is confined to the Neuse and Tar drainages (Taylor 1969), but 
may have been present in the Roanoke prior to habitat destruction by 
dams and pollution (C. R. Gilbert, pers. comm.). Memdia extensa and 
Etheostoma perlongum are endemic to Lake Waccamaw, and Fundulus wacca- 
mensis is confined to lakes Waccamaw and Phelps (see zoogeographic dis- 
cussions in Hubbs and Raney 1946; Jenkins et al. 1972; and Bailey et al. 
1977). Phelps Lake F. waccamensis have not been critically examined, and 
introduction from Lake Waccamaw is considered a possibility. 
Twenty-four native species are uniformly distributed throughout 
coastal North Carolina drainages: Lepisosteus osseus, Dorosoma cepedianum, 
Anguilla rostrata, Umbra pygmaea, Esox americanus americanus, E. mger, 
Notemigonus crysoleucas, Notropis chalybaeus, Enmygon oblongus oblongus, 1c- 
talurus natahs, Noturus gynnus, N. insignis, Aphredoderus sayanus sayanus, Gam- 
busia affinis holbrooki, Acantharchus pomotis, Centrarchus macropterus, En~
