Anal papilla generally distinct. GiU-opening vertical, of moderate 

 width, the gill-membranes being united to the isthmus ; branchio- 

 stegals five ; gills fom-, pseudobrancliiae ; au--bladder none, or, if 

 present, very small. Pyloric appendages none. Vertebrae ji^. 



Eonnd on all the coasts of the temperate and tropical regions, 

 many species entering fresh waters, and some entirely confined to 

 them. 



The attempts to di\-ide the numerous species of this genus into 

 smaller groups have failed to establish natural genera. The cha- 

 racters which may be used for that purpose — as the form of the body, 

 the stnictiu'e and size of the scales, modifications of the dentition,

 transitions between the most extreme forms, or such species are
