an addition to the ichthyofauna of the speciose Licking River system 

 and reduces the distributional hiatus among known populations in the 

 upper and middle Ohio River drainage (Zorach 1972). Ahhough pre- 

 vious surveys of the Licking River have not revealed E. camurum 

 (Woolman 1892; Welter 1938; Clark 1941a, b; Jones 1970), other 

 members of the subgenus Nothonotus (i.e., E. maculatum Kirtland and 

 E. tippecanoe Jordan and Evermann) have been reported from the 

 drainage (Woolman 1892; Clark 1941a, b; Burr 1980). However, E. 

 maculatum, often confused with E. camurum (Zorach and Raney 1967), 

 is known in the drainage only from a collection made by J. A. Henshall 

 in South Fork (Woolman 1892). Henshall apparently recognized both 

 species, according to details presented in Trautman (1981), and the E. 

 maculatum record is considered valid by some authors (Zorach and 

 Raney 1967; Burr 1980), although Etnier (1980) did not include the 

 Licking River in its distribution. We speculate that E. camurum was 

 missed in the Licking River by previous investigators because popula- 

 tions are often localized (Stauffer 1980). Moreover, large stream or river 

 habitat often occupied by members of the subgenus Nothonotus is diffi- 

 cult to collect and has elsewhere recently yielded species missed during 

 many years of collecting (Williams and Etnier 1978). Our specimens 

 were collected from a 0.3-0.6 m deep riffle habitat with moderate to 

 swift current. Substrate consisted of bedrock overlain with slab boulder 

 where the current was swiftest, and cobble/ gravel in areas of moderate 

 flow. Additional collecting in the poorly sampled mainstem of the Lick- 

 ing and South Fork Licking rivers (Burr 1980) is necessary to determine 

 the extent of distribution of E. camurum and to verify the existence of 

 E. maculatum in the drainage.

According to Page (1978) and Burr (1980), the longhead darter 

 occurs sporadically in Kentucky in the upper Barren, upper Green, Ken- 

 tucky, Licking, and Big Sandy river systems and Kinniconick Creek and 

 has apparently been extirpated from the Cumberland River. Burr (1980) 

 noted that the species was once common in the Barren River prior to 

 impoundment of Barren River Reservoir as indicated in pre-
