 Habitat. — All streams from Labrador to Florida and westward to the Rockj' Mount-

 Mullet, Chub Sucker, etc. 



This species is subject to considerable variations in different waters. 

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

 nuiddy 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 IJ to 3 inches in length 

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