JV. — WATER BASIN OF THE CHATTAHOOCHEE RIVER. 



Our collections in tbe Chattahoochee Basiti 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 thoreauianus, Photogenis (cucopiis, and Codoma eury- 

 stonia. Tbe 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 

 [Ambloplites rnpestris) and the Eed Horse {Myxostoma duquesnii), as the 

 westernmost limit of the range of the " Green Cat" {Amiurus brunneus), 

 the War-mouth Perch [ChcenobryUus viridis), and the "Jump Eocks" 

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

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

 in which Lnxilus cornutus does not occur.
