UPPER TENNESSEE DRAINAGE. 557 



Reported from Tennessee River, below Knoxville (Lewis), and 

 the Holston River (Call). I have never found it in the Holston, but 

 only in the Clinch, at Edgemoor and Clinton, Anderson Co., Tenn. ; 

 at Oakman, Grainger Co., Tenn. In the Walker collection it is from 

 Clinch River at Clinchport, Scott Co., Va. ; and I collected it still 

 farther up at St. Paul, Wise Co., and Cleveland, Russel Co., Va. It 

 is undoubtedly a rare shell. 



Type locality: Kentucky River.

A characteristic small stream species, abundant locally, and re- 

 ported by Lewis from small streams in Monroe Co., Tenn., and by 

 Call from tributaries of the Holston in East Tennessee. 



The largest streams where I have seen it are the upper Holston 

 proper at Church Hill, Hawkins Co., Tenn., and the Hiwassee, at 

 Austral, Polk Co., Tenn. In both cases the specimens came from a 

 small slough. In the headwater streams, it is in upper Powell, in 

 Va., in the uppermost Clinch in Tazewell Co., Va. ; in Little Mocassin 

 Creek, Scott Co., Va. ; South Fork Holston at Bluff City, Sullivan 

 Co., Tenn. ; Watauga River, Carter Co., Tenn. 



Other small streams are the following: Cove Creek, Campbell 

 Co., Tenn. (to Clinch) ; Bull Run, Knox Co., Tenn. (to Clinch) ;
