The mud bass, -which lives in sluggish fresh waters along the coast from New 

 York to South Carolina, is known from the Neuse near Raleigh and at Kinston; 

 from the Tar near Rocky Mount; and from Lake Ellis in Craven County. It 

 doubtless exists in various other state waters in which no collections have been 

 made. Its length is about 6 inches, and its food value is slight. It lives mostly 

 in muddy water, and is said to be nocturnal in its habits.
