We have now completed the survey of the principal land-masses of the globe. We shall conclude with a reference to one of the largest islands of the world, viz. New Zealand, with which will be included a few outlying islands such as the Aucklands, Snares Island, etc. The reason for not ignoring these islands as we have ignored certain other islands of large size, such as Japan, will be apparent from the peculiarity of the earthworm fauna which they show. From New Zealand the Moniligastridae, Geoscolecidae, Lumbricidae, and, of course, the Eudrilidae, are absent, save the ubiquitous _Eudrilus_. The only family of earthworms which is here represented is that of the Megascolecidae. Of this family the Acanthodrilinae are very well represented. We have at any rate seven species of the genus _Notiodrilus_ of which the bulk are from the small adjacent islands and not from the mainland. The genus _Rhododrilus_ with nine species is actually limited to the New Zealand group and so is an allied genus consisting of two species only, viz. _Leptodrilus_. This latter genus is confined, so far as present information goes, to the Auckland and Campbell islands. _Dinodriloides_ with two species is also limited to New Zealand and to the North Island. _Maoridrilus_ with some ten species is another native and restricted genus. So too is the allied _Plagiochaeta_ with numerous setae on each segment but with the alternating and single nephridial pores of _Maoridrilus_. There are several species of _Plagiochaeta_ of which one has been lately regarded by Dr Michaelsen as really falling within the otherwise Indian genus _Hoplochaetella_, while for another he has formed the genus _Pereiodrilus_. _Neodrilus_ with but one species _N. monocystis_ is another peculiar New Zealand genus. The family Octochaetinae contains only four genera, of which one, viz. _Dinodrilus_ (with four species), is limited to New Zealand, while _Octochaetus_ has about five representatives. _Hoplochaetella_ (if Dr Michaelsen's surmise referred to above be correct) has one species in New Zealand. The Megascolecinae are less numerous than the Acanthodrilinae, but there are ten species of the genus _Megascolides_ (which includes Benham's genus _Tokea_), perhaps seven species of _Diporochaeta_, and two other species which Michaelsen has removed from the genus _Diporochaeta_ and placed in _Spenceriella_. One _Plutellus_ (which however may have been introduced) completes the New Zealand Megascolecines. We have therefore in this part of the world fifteen genera including between them some 58 species; eight of the genera are peculiar to the islands.
