This little fish departs but in a small degree in likeness 

 from the general family of the Lampreys, but it differs from 

 most of them in its characteristic habits; and especially in its 

 little disposition to wander from its accustomed haunts, or its 

 place of shelter and concealment; Avhich is in the beds or 

 accumulations of sandy mud at the border and eddy of the 

 smaller brooks; and from which it seldom emerges; so that 

 however numerous, it would scarcely be known if not sought 

 for by fishermen to serve as a bait in icldjfing for Pollacks. 

 Buried in scattered companies in the soft soil, it may be said 

 to lead the life of the mole; and it is there it finds all it 

 Avants of food; in search of which by taste or scent it moves 

 through its tracks as appetite or disposition prompts; and from 

 observation it may be judged that except in search of new 

 feeding ground, it never willingly exposes itself to the dangers
