Part II. Chattahoochee River. 



While waiting for a train at Atlanta, we were enabled to 

 spend part of a day in studying the fishes of the tributaries 

 of the Chattahoochee River. We first tried Peach Tree 

 Creek, some five miles north of the city. This stream is 

 deep and excessively muddy, and we secured nothing of note. 

 We then proceeded to Pace's Ferry on the Chattahoochee, 

 but the canes on the shores and the snags and rocks in the 

 water, prevented us from accomplishing any thing. We 

 then struck a clear rapid stream known as Nancy's Creek, a 

 mile or two above its mouth, and secured the species below 

 enumerated. It is to be noticed that the waters of the 

 Chattahoochee, like those of the Etowah, find their way to 

 the Gulf, while the Ocmulgee, whose source is only a few 

 "miles distant, flows into the ocean.

* Helioperca Jordan, gen. nov. This genus differs from Lepiopomus in the absence 

 of palatine teeth, and in the structure of the gill rakers, which are more slender than 

 in Lepiopomus and beset with fine prickles, like the stem of a briar. The type is 

 Labrus j)allidus Mitch. [ — Pomotis incisor C. and V.). Pomotis obscurus Ag. and 

 Lepiopomus isehyrus Jor. and Nelson, Mss., belong to Helioperca. The etymology is 

 "Helios, sun, and perke, perch, suggesting the vernacular name of "Sun-fish," universal 

 in this country.
