54 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY III. 



Genus SEMOTiLUS Eafinesque. 

 43. SEMOTILUS COEPORALIS (Mit.) Putnam. 

 Common in the smaller streams. 



Genus KHINICHTHYS Agassi*. 

 44. EHINICHTHYS OBTUSUS Agassiz. 



Very common in the spring-runs tributary to the Etowah and Oosta- 

 naula. 



OATOSTOMIDJS. 



Genus MYXOSTOMA Eafinesgue. 

 45. MYXOSTOMA MACROLEPIDOTUM DUQUESNII (Le 8.) Jordan. 



The "Bed Horse" is common in the Etowah and Oostanaula. Var. 

 lachrymale (Cope) also occur. 3. 



46. MYXOSTOMA ETJRYOPS Jordan. 



Myxostoma euryovs JORDAN (1877), Ann. Lye. Nat. Hist. N. Y. 348. 



From Lovejoy's Creek, a tributary of the Oostanaula. The type-speci- 

 men of this singular species still remains unique. 



Genus CATOSTOMUS Le Sneur. 

 47. CATOSTOMUS NIGRICANS ETOWANUS Jordan. 



Catostomus nigricans var. etowanus JORDAN (1877), Ann. Lye. Nat. Hist. N. Y. 



The Hog Mullet, -or Crawl- a-bottom, is very abundant in all rapid 

 streams in the Alabama Basin. The characters separating var. etowa- 

 nus from nigricans seem to be pretty constant. I do not, however, 

 think them distinct species. 



Genus ERIMYZON Jordan. 

 48. ERIMYZON SUCETTA (Lac.} Jordan. 



This species, known locally as the May Sucker, is abundant in the 

 water-basin of the Alabama. 



Genus MINYTREMA Jordan.

 The "Sand Sucker 7 " is abundant in the waters of the Alabama.
