Map 5. — Distribution of Noturus insignis (Richardson). Circles indicate the localities from 

 which T have examined specimens. The dashed line outlines the known limit of distri- 

 bution and surrounds localities for which there are unconfirmed literature records. 



N. insignis is believed to be a native inhabitant of tributaries to the Atlantic Ocean 

 from Georgia to New York and the upper Kanawha River system. It was probably intro- 

 duced by man into New England and has crossed into the Lake Ontario drainage, the 

 upper Tennessee River basin, and other tributaries of the Ohio River in Maryland, 

 Pennsylvania, and West Virginia.
