lake, and in the headwaters of the river just below the dam. The Wac- 

 camaw killifish typically inhabits the shallow, sandy shoreline of the 

 lake where it is often associated with dense stands of Panicum hemito- 

 mum. No specimens have been taken in the river farther than 100 m 

 below the lake. Stations: la,b,c,d,e,f,g,h,i,l, 2a,b,c, 3, 4, 5, 6, 7. 



Poeciliidae — livebearers 



Gambusia affinis (Baird and Girard), mosquitofish. The mosquito- 

 fish was collected throughout the entire system in nearly every habitat 

 type sampled, but was never collected while trawling at mid-lake sta- 

 tions and was only rarely taken at other stations within the lake. Sta- 

 tions. la,b,c,d,e,f,g,h, 2a,b,c, 3, 4, 5, 6, 7, 8a,b,c,d, 9, 10, 12, 14, 19, 20, 

 21, 22, 27a,b, 28, 29a,b,c, 30, 31, 33, 34, 36, 37, 38, 39, 40, 42, 43, 44, 49,

Heterandria formosa Agassiz, least killifish. This diminutive poecil- 

 iid was only collected from one station in the South Carolina section of 

 the Waccamaw River, and is probably more abundant in the extreme 

 lower reaches of the river. Fowler (1935) reported it from Waverly 

 Mills, South Carolina (Waccamaw drainage). Station: 42. 



Atherinidae — silversides 

 Menidia extensa Hubbs and Raney, Waccamaw silverside. The 

 Waccamaw silverside is possibly the most abundant fish in Lake Wac- 

 camaw. It also has the most limited distribution of the described 

 endemic species in the lake. Specimens have never been collected in Big 

 Creek or the canals surrounding the lake. A few stragglers (washovers) 

 are occasionally taken below the dam, but never more than 30 or 40 m 

 downstream from the lake. This species inhabits open, non-vegetated 

 waters along the shoreline of the lake and is occasionally taken in off- 

 shore waters. Stations: la,b,c,d,e,f,g,h,i, 7. 



Percichthyidae — temperate basses 



Morone americana (Gmelin), white perch. The white perch is 

 common in Lake Waccamaw and is considered to be the predominant 

 game species there. It was encountered, often in large numbers, at mid- 

 lake trawl stations. Except for one adult from Big Creek and another 

 from below the dam, the species was not collected outside the lake dur- 

 ing our survey. The specimen from Big Creek was injured and may have 

 been released by a fisherman. R. H. Moore (pers. comm.) reported 

 white perch from the lower Waccamaw River and Winyah Bay in South 

 Carolina. Stations: la,b,c,e,f,g,i, 2a, 7. 



Morone saxatilis (Walbaum), striped bass. Baker (1968) indicated 

 that this anadromous species runs up the main channel of the Wac- 

 camaw River almost as far north as Juniper Creek. No specimens were 

 collected during our survey.
