We did not collect two of the seven species considered to be endan- 

 gered, the paddlefish and dusky darter, and believe that they have been extirpat- 

 ed from the state. The cutlips minnow in North Carolina is restricted to the Dan 

 River, where we found it in 2 1 rkm rather than the 1 .6 rkm in which it was pre- 

 viously known; this population at present appears to be secure. The rustyside 

 sucker in North Carolina is confined to the downstream reaches of the Little Dan 

 River, where it is extremely rare. We discovered that the North Carolina distri- 

 bution of the stonecat is significantly larger than the small portion of the Cane 

 River from which it was previously known, and to also include the Ivy River and 

 the Little Tennessee River. Nevertheless, its status of endangered is warranted. 

 The orangefin madtom in North Carolina is restricted to the Dan and to the Lit- 

 tle Dan rivers; its distribution there appears to have decreased. The blotchside 

 logperch in North Carolina has been extirpated from historical sites in the French 

 Broad River system, and it is today restricted to 24 rkm of the South Toe River; 

 its continued existence there appears to be tenuous.

Records of all six North Carolina species considered threatened were 

 collected in our survey. The American brook lamprey in North Carolina is 

 known only from the downstream portion of Spring Creek; consequently, we
