  Ceratodus \Ce*rat"o*dus\, n. [NL., fr. Gr. ke`ras, ke`ratos horn
     + ? tooth.] (Zool.)
     A genus of ganoid fishes, of the order Dipnoi, first known as
     Mesozoic fossil fishes; but recently two living species have
     been discovered in Australian rivers. They have lungs so well
     developed that they can leave the water and breathe in air.


     In Australia they are called {salmon} and {baramunda}. See
     {Dipnoi}, and {Archipterygium}.
