Salvelinus fontinalis. — The Brook trout is indigenous to much of the Ap- 

 palachian Plateau and natural populations are to be found in pristine 

 habitats common to Gauley River headwaters. 



Cyprinidae 



Campostoma anomalum. — The Stoneroller is common throughout the up- 

 per Kanawha River drainage. Addair (1944) collected it from eight of 19 

 sampling localities on Gauley River. This survey reports it from 27 of 52 

 stations. Verified museum records are CU 32399; UMMZ 95280, 95293, 

 108166, 108176, 165698, 165705, 165754. 



Clinostomus funduloides . — Addair (1944) reported the Rosyside dace 

 from two Kanawha River localities, one of which was on Meadow River 

 near Russelville (Station 30, Fig. 1). Hocutt et al. (1978) reported it from 

 three localities in the Greenbrier drainage. It was found in this survey at 

 five stations: Cherry River (Stations 17 and 20) and Meadow River (Sta- 

 tions 38, 39, 40). Its distribution appears limited to higher elevations and 

 colder waters. Another record is from Cherry River (UNC 3315). 



Encymba buccata. — Addair (1944) collected the Silverjaw minnow in six 

 of 87 collections above Kanawha Falls, including three localities in the 

 Gauley drainage: Twentymile Creek, Peters Creek and Williams River. It 

 was common at ten of the 20 localities where we collected it. Factors af- 

 fecting its distribution (Wallace 1972; 1973) appear to be favorable under 

 present conditions. Previous museum records are UMMZ 95294; USNM 

 (RVM-260). 



Exoglossum laurae. — The Tonguetied minnow was collected by Addair 

 (1944) at three Williams River localities. It was not abundant in this sur- 

 vey, with only eight specimens collected from headwater stations of 

 Williams River (Station 11, AEL 182), Cranberry River (13, AEL 163) 

 and Cherry River (17, AEL 183; 18, AEL 175). 



Nocomis platyrhynchus . — The Bigmouth chub is endemic to the upper 

 Kanawha River drainage above Kanawha Falls (Lachner and Jenkins 

 1971). The sibling species, jV. micropogon, occurs commonly in all other 

 drainages of the greater Ohio River, including the lower Kanawha River, 

 and Atlantic slope heading in West Virginia. Many diagnostic charac- 

 teristics of the two species are similar, with overlap occurring between 

 morphometric and meristic ranges; it is distinguished from TV. 

 platyrhynchus chiefly by tuberculation patterns. Despite six new dis- 

 tributional records for fishes above Kanawha Falls, it was necessary to 

 consider all micropogon-group chubs collected in Gauley River as JV. 

 platyrhynchus for the reasons cited. 



Addair (1944) collected N. platyrhynchus from five localities. This survey 

 found it at 23 stations where it was often abundant. The use of elec-
