We already know two species of Notiodrilus from these 

 southern islands — viz., N. macquariensis, Beddard, originally 

 described some years ago, and more recently studied and illus- 

 trated by myself,* and N. aucMandicus, described by myself in 

 1902. Hitherto these two worms have been the only Oligochseta 

 recorded from this region, and the other islands have been un- 

 explored for this branch of their fauna. The present contri- 

 bution thus adds a third species of Notiodrilus,^ as^well as two 

 new species of Rhododrilus, which is endemic in New Zealand, 

 and, unlike some of our other genera, is represented alike in 

 the North and South Islands, as well as in the Chathams. 

 The presence, too, of Enchytreeids in these southern islands is 

 of interest, as species of both Marionina and Lumbricillus have 

 been recorded from South Georgia and Tierra del Fuego, while 

 the same species of Enchytrceus has been met with all over the 



globe.
