IV. — WATER basin OF THE CnATTAHOOCHEE RIVER. 



Our collections in the Chattahoochee 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 : Semotilus thorqauianus, Pliotogenis leucopus, and Codotna eury- 

 stoma. The other species taken are found also either in 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 

 {AmblopUtes rnpcstris) and tlm Red Horse {Myxosioma duquesnii), as the 

 westernmost limit of the range of the " Green Cat" {Annnrns brnnneus), 

 tl)e War-mouth Perch [Chwnobrythin viridis), wwd the "Jump Rocks " 

 [Myxostoma cervinum). It is also the westernmost of the series of riv- 

 ers — Great Pedee, Santee, Sav.vnuah, Altainahu, and Chattahoochee — 

 in which Lnxilus cornutus does not occur.
