C4E0GRAPHICAL RELATIONS. 



The only endemic (fenus is Leptodrilus, which is closely related to a, purely New 

 Zealand genus, Rhododrilus, in which, indeed, I formerly included it. This new 

 genus, represented by two species, occurs both on the Auckland and on the Campbell 

 Islands, as does also Eliododrilus.
