FISHES OF THE ALABAMA BASIN. 45 



Alabama Basin. These are: Xenisma steUifenon, Ztjgonectes gnftafus, 

 Zygonectes hieroglr/phicus, HydropJdox xa'noccphalus, Hydrophlox chroso- 

 mns, Codoma calUstia, Codoitia trichroisiia, Codoma ccendea, Codoma 

 stigmatura, JS'^otropis siilbinsj Fhcnacohiiis catostomus, Catostomus nigri- 

 cans etov anus, and Myxostoma euryops. 1 exclude from this enumeration 

 one or two species recorded from the Black Warrior Eiver, as it is 

 l;kely that the fauna of that stream will prove, in part at least, dififereut. 

 Certain comniou Xorthern or Western types, apparently absent in the 

 streams hitherto noticed, make their appearance in the waters of the 

 Alabama. Among these are Lnxilus cormitus, Notemigonns chrysoleucus, 

 CItcenobrytfus gulosus, Hyodon, Phenacobiiis, etc.

Louisiana. 



Genus BOLEICHTIIYS Girard. 



4. BoLEiCHTHYS ELEGANS Girard. 



Abundant in clear, weedy ponds. This may not be identical with 

 Girard's species, which was originally described from Texas. 



VERCIDM, 

 Genus STIZOSTETHIUM Rafinesque. 



5. STIZOSTETHIUM SALMONEUM Rafmcsquc. 



In the river-channels of the Oostanaula. We have had no opportu-

 is the original salmoneum.
