FISHES OP NORTH CAROLINA. 



This exceedingly beautiful sun-fish inhabits lowland waters from Virginia 

 to Louisiana, and the Mississippi basin as far north as Illinois. It is common in 

 Roanoke and Neuse rivers, is also known from Tar River, and doubtless occurs 

 in all other coastal streams. Its small size, 6 or 7 inches, renders it unimportant 

 as a food fish, but it is used locally , at Plymouth and other places, being caught 

 in slat-weirs, seines, etc. It shares with other species the name of "sun-fish" 

 but is also known locally as "flier" and "mill-pond perch", designations which 

 seem to be used only for this species and in this state.
