Area 8. — It is most closely related to 1. Of the 45 genera 76 

 species there are 5 genera 20 species absent from 1 ; 6 genera 

 37 species absent from 7 ; 13 genera 50 species not in 9. Area 9 

 seems to repel 8 ; 8 is in strong sympathy with 1, and slightly so 

 with 7. Genera absent in 1, Eniblema, Amytis, Acrocephalus 

 (the only gap) ; in 9, Cisticola, Philemon, Myiagra, Munia, Peophila ; 

 in 7, Stipiturus, Pcecilodryas, Neochmia, Munia. The following 

 species are peculiar to this area : — Malurus coronatus, Gerygone 

 cinerascens, Cinclosoma marginatum, Pachycephala lanioides. 



Area 9. — It has 59 genera 93 species, and seems to be derived in 

 two ways — from 6 and 7. Genera in 9 absent from 6 are — Psophodes, 

 Atrichia, Stipiturus, and Sphenura (all in area 4), while those absent 

 in 7 are Stipiturus, Acanthorynchus, Meliornis, Pseudogerygone. 

 From this, and remarks under 6, it would appear the avifauna of 

 the south-west is largely derived from 6, that of the west proper 

 from 7. The genera here absent from 8, or very feebly represented 

 by a single species in sparse quantity, are those strong ones of 

 the east and south-east — Sericornis, Acanthiza, and Zosterops ; 

 others being Amytis and Gymnorhina. Three-fourths of the species 

 and half the genera of 9 are absent from 8. In 9 there are 4 genera 

 (also in 4) and 37 species that are not in 6, while in 6 there are 11 

 genera and 61 species that are not in 9. Present in 9, but absent in 

 7, are 7 genera and 36 species, while there are 16 genera and 64 

 species in 7 absent in 9. To this area there is no Passerine genus 

 peculiar, but there are 17 species. In the order Psittaci there is 

 Porphyrocephalus confined to 9. 



In a more limited way the smaller orders help to support this 

 scheme of distribution, the idea of which was in part suggested 

 by Professor Baldwin Spencer, Hon. Director of the National 

 Museum.
