This darter secretes itself on the bottom in small clear brooks, 

 iwimming rapidly for a short distance when alarmed. The sexes 

 ire very different in appearance, the males having higher and 

 nore brightly colored fins than the females. The males are 

 arger than the females and in the spring are much spotted with 

 )lack. The common darter, or tessellated darter, is found from 

 Massachusetts to Georgia. It is replaced in Cayuga lake and 

 some other regions to the southward by a black spotted variety, 

 vhich differs from the common form still further in having the 

 lape and breast closely scaled. De Kay states that it occurs 

 n most of the fresh-water streams of the state. It is found in 

 L/ake Champlain. Evermann and Bean took it in Scioto creek,
