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. j 



The yellow-bass might be called a cousin of 

 the white-bass, though it belongs to a different

 a body not quite so deep ; otherwise the general 

 shape is much the same. The mouth is a little
