did not collect it in the French Broad River system, but we collected one juve- 

 nile (38 mm SL) in the Cane River on 19 July 1993, and three adults (104 mm 

 SL, two released) in the South Toe River on 5 September 1993 (Fig. 8). Pre- 

 ferred habitat is around large boulders in fast riffles. Its status of special concern 

 in North Carolina appears to be conservative. 



NEW STATE RECORD 



Ohio lamprey Ichthyomyzon bdellium (Jordan) 



The Ohio lamprey occurs in disjunct populations in the Ohio River 

 basin, where it is uncommon (Rohde and Lanteigne-Courchene 1980). Because 

 of its presence in nearby Tennessee, Menhinick et al. (1974) listed its occurrence 

 in North Carolina as probable. However, there were no records from North Car- 

 olina until we took one male and three females from the mouth of Spring Creek, 

 Madison County, on 14 May 1994 (Fig. 9). Each was adult (220-260 mm TL), 

 had a well-developed digestive tract, and each female was gravid. We took 

 another three males (243-246 mm TL), one female (244 mm TL), and two juve- 

 niles (not ammocoetes, nor mature adults) (152, 153 mm TL) here on 22 April 

 1995, as well as two adult males (239, 248 mm TL) 1 rkm further upstream in 

 this creek on the same day. We took three females (235-240 mm TL) in nearby 

 Paint Creek, Greene County, Tennessee on 14 May 1995. All our specimens 

 were taken over rocky riffles with a current from 0.45-0.78 m/sec.
