uniform height; anal short and rati) or liigh; air bladder 

 large, cellular, lung -like, communicating by a glottis 

 with the oesophagus; stomach large. 



A single species is found in the larger bodies of fresh 

 water in the U. S. from N. Y. to the plains. It is 

 exceedingly tenacious of life, even more so than the 

 species of Amiurus. The flesh is soft and pasty, and 

 not edible. In some regions its voracity has acquired 

 for it the name of " Lawyer," because, as has been said, 

 " it will bite at any thing, and is good for nothing when 

 caught."
