Fishes of Upper Georgia. 325 



This species is very abundant in Dyke's Pond and other 

 mill-ponds tributary to the Etowah River, where it is known 

 as Jack. 



I recognize E. affinis as a variety even, solely on the author- 

 ity of Holbrook and Cope. Careful comparison of specimens 

 of " reticulatus" from the Delaware and Housatonic rivers, 

 with "affinis" from the Etowah and Ocmulgee, fails to 

 show any permanent difference whatever. The alleged 

 greater number of dorsal and anal rays in the northern fish 

 is due simply to Storer's having counted the rudimentary 

 rays or "stubs," while Holbrook counted only the developed 

 ones. It is the difference between "D. 17" and "D. II, 

 15." There is no obvious difference in dentition. The col- 

 oration varies somewhat, but my brightest colored specimens 

 are from the clear tributaries of the Etowah, and the dullest 

 from the muddy Ocmulgee.
