 Coast of Maine (W. C. Kendall) to Cape Hatteras, in river mouths, ascend- 

 ing streams to their fountain heads, hence abundant in lakes throughout 

 New York; variety menona westward to northern Illinois; not found 

 southward. The typical form found eastward and in the sea has the back 

 nearly or quite unspotted. Examples from Grand Lake Stream and Boy- 

 deu Lake, Maine, have the back somewhat spotted. In the Potomac River 

 this is the most abundant species of the family, (diajihanux, 6ia<pav>/^, 

 transparent.)
