 stream east of the Rocky Mountains. In Canada, iu New England, in 

 the Great Lakes, in the Mississippi Valley, iu South Carolina, in Georgia, 

 in Alabama, it is everywhere the commonest Sucker, and it certainly 

 occurs in Dakota, Nebraslui, Kansas, Colorado, and Texas, though how 

 abundantly I am unable to say. 



This species is everywhere the one to which the name of "Sucker" 

 primarily belongs, rhe other species, though often called "Sucker", as 

 a sort of general term, receiving the special names of Red Horse, Buffalo, 

 Mullet, Chub Sucker, etc. 



This species is subject to consideruible variations in different waters. 

 In shaded brooks, it is dark-colored and rather slender. In open or 

 muddy waters, it becomes pale. In the Great Lakes, it often reaches a 

 considerable size and a proportional stoutness of body. The adult is 

 usually uniformly colored above. Young fishes 1^ to 3 inches in length 

 are often variegated, and sometimes show tliree or four lateral dark
