The Bass Family 91 



named it interrupta, in allusion to the broken or 

 "interrupted" lines along its sides. It is also 

 known as brassy-bass. It belongs to the same 

 genus as the white-perch of the East Coast. It 

 is found only in the lower Mississippi River and 

 its tributaries, sometimes extending its range a 

 short distance up the Ohio River. 



The yellow-bass might be called a cousin of 

 the white-bass, though it belongs to a different 

 genus. It takes the place of that fish in the 

 lower Mississippi Valley. Compared with the 

 white-bass it has a somewhat longer head, with 

 a body not quite so deep ; otherwise the general 

 shape is much the same. The mouth is a little 

 larger, though the snout does not project quite so 

 much, and the profile of the head is straighter, 

 and it has a larger eye. The posterior border of 

 the cheek-bone is finely serrated. 



The general color is brassy or yellowish, 

 darker on the back and lighter on the belly. 

 There are about half a dozen very distinct and 

 black longitudinal lines along the sides, the lower 

 ones broken or " interrupted," the posterior por- 

 tions dropping below the anterior, like a " fault " 

 in a stratum of rocks. 



It is fond of the deeper pools in the rivers and 



£i.
