This species is quite abundant in the more sluggish streams 

 tributary to the Etowah and Oostanaula. My specimens 

 from the south are uniformly more slim than those from 

 Indiana. They have also longer and narrower heads, and 

 larger scales. Their coloration, too, is more uniform. All 

 the Georgia specimens examined have the teeth 1, 4-4, 0, as 

 stated by Agassiz and Cope, in Tennessee Eiver specimens. 

 Those from the north have the teeth uniformly 0, 4-4, 0. 



The southern form may then be taken as a variety, to 

 which Storer's name, prolixum, may be applied. Storer's 

 short and irrelevant description might refer to several other 

 species as well as to the present one, but Prof. Agassiz lo- 

 cates it here. 



The tendencies of the two varieties are shown by the fol- 

 lowing table of the average of the measurements of several 

 specimens of each.
