Head 4; depth 4* ; eye large, 3i in head. D. 13; A. 11; scales 45-15. 

 Body rather slender, not elevated, compressed posteriorly. Head moder-

 not large ; dorsal and anal rather low ; ventrals scarcely reaching vent 

 in the females ; somewhat longer in the males. General color olivaceous ;

 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- 

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

 this is the most abundant species of the family, (diaphanus, titaQavfc, 

 transparent.)
