IV. WATER BASIN OF THE CHATTAHOOCHEE RIVER. 



Our collections in the Ctmttahoochee Basin have been rather unsatis- 

 factory, as only twenty-one species have been obtained. Of these, three 

 seem to be characteristic of the river, and have not yet been obtained else- 

 where : Scmotilus tlwreauianus, Photogenis leucopus, and Codoma ennj- 

 stoma. The other species taken are found also eitherjn the Altamaha 

 or Alabama, or both. 



The Chattahoochee is noteworthy as being, so far as is at present 

 known, the easternmost limit in the Southern States of the Rock Bass 

 (Ambloplites rupestris) and the Red Horse (Myxostoma duquesnU], as the 

 westernmost limit of the range of the u Green Cat" (Amiurus brunneiis], 

 the \Yar-mouth Perch (Cliasnobryttus viridis), and the "Jump Rocks" 

 (Myxostoma cervinum). It is also the westernmost of the series of ri\ T - 

 ers Great Pedee, Santee, Savannah, Altamaha, and Chattahoochee 

 in which Luxilus cornutus does not occur.
