 3. Ohio R. (New Albany, Dr. Sloan) to Arkansas R. 

 and S. (Type of Alburnellus.)

 D. I, 8; A. 1, 10; lat. 1. 38; L. 4 to 5. Great Lakes and 

 Ohio Valley; abundant in the larger streams; even more

 Rafinesque s &quot; Emerald Minnow,&quot; the type of his genus 

 Minnilus. Rafinesque s generic name having nearly 

 forty years priority over Alburnellus^ must be substituted 

 for the latter appellation.)
