Louder (1962a) reported two specimens from the northeast shore of Lake 

 Waccamaw, and we collected one specimen from the lake. Specimens 

 identified by Fowler (1935) as Erogalaformosa (Putnam) {-N. hypselopter- 

 us) from the Waccamaw drainage were determined to be a mixture of N. 

 chalybaeus and N. cummingsae. Notropis chalybaeus was often found in 

 association with N. petersoni, although it was never as numerous. Sta- 

 tions: lg, 7, 19, 28, 29a,c, 39, 49. 



Notropis cummingsae Myers, dusky shiner. The dusky shiner also 

 appears to be largely confined to the main channel of the river. Small 

 schools were often encountered in open parts of the river, generally those 

 lacking dense vegetation. There are no reports of the species from Lake 

 Waccamaw. Stations: 7, 8a,d, 19, 27a, 28, 29a,c, 50. 



Notropis hudsonius (Clinton), spottail shiner. Louder (1962b) 

 reported seven specimens of the spottail shiner from Big Creek, the prin- 

 cipal feeder stream to Lake Waccamaw. Records also exist from the Wac- 

 camaw River in North Carolina (Menhinick, ms.; Gilbert and Burgess 

 1980). According to Gilbert and Burgess (1980), this species inhabits 

 large, sluggish coastal rivers and brackish waters on the Atlantic slope. 

 The Big Creek locality does not fit this habitat description. The pre- 

 viously mentioned records for N. hudsonius, especially Big Creek, may be 

 based on misidentifications. However, museum specimens for these 

 records in the Waccamaw drainage could not be located for examination. 

 During our survey, no spottail shiners were collected. 



Notropis maculatus (Hay), taillight shiner. This cyprinid is distrib- 

 uted throughout much of the Waccamaw system. Louder (1962b) found 

 it in Bogue Swamp, but it does not appear to be present in Lake Wac- 

 camaw. However, one population was located in a canal on the southwest 

 shore of the lake, and another in Big Creek not far from its mouth. Other 

 populations exist in the mainstream of the Waccamaw River. Stations: 

 2a, 6, 29a, 37, 38. 



Notropis petersoni Fowler, coastal shiner. This is perhaps the most 

 widespread and abundant cyprinid throughout the system. The Lake 

 Waccamaw population was originally described at Notropis waccamanus 

 by Fowler (1942) and later placed in the synonymy of N. petersoni by 

 Frey (1951). Davis and Louder ( 1 97 1 ) discussed the biology of the species 

 in North Carolina waters (including Lake Waccamaw). We encountered 

 it in all habitat types sampled, with the notable exception of the canals 

 around Lake Waccamaw. Stations: l,a,b,c,d,e,f,g,h,i,l,m, 2a, c, 7, 8a, b, 

 19, 27b,c, 31, 37, 38, 39, 40, 42, 44, 47, 49, 50. 



Catostomidae — suckers 



Erimyzon oblongus (Mitchill), creek chubsucker. This species is 



common throughout the system in a wide variety of habitats. Frey 



(1951) first reported it from Lake Waccamaw, and apparently our single 



specimen represents the only other published record from the lake. We
