We have thus a wonderful amount of speciality; yet the affi- 
nities of the fauna, whenever they can he traced, are with Aus- 
tralia or Polynesia. Nine genera of New Zealand birds are 
characteristically Australian, and the eight genera of wide range 
are Australian also. Of the peculiar genera, 7 or 8 are undoubtedly 
allied to Australian groups. There are also four Australian and 
one Polynesian species. Even the peculiar family, Nestoridse, is 
allied to the Australian Trichoglossidae. We have therefore every 
gradation of similarity to the Australian fauna, from identical 
species, through identical genera, and allied genera, to distinct 
but allied families; clearly indicating very long continued yet 
rare immigations from Australia or Polynesia; immigrations which 
are continued down to our day. For resident ornithologists be- 
lieve, that the Zosterops lateralis has found its way to New Zea- 
land within the last few years, and that the two cuckoos now 
migrate annually, the one from Australia, the other from some
