The genus Sericulus is peculiar to 3, but only two species Menura 

 alberti and Collyriocincla cerviniventris are limited to it. 



AREA 4. This is the southern extension of 3, and with it is closely 

 associated 5 ; indeed, the latter may be expanded as a southern 

 offshoot of 4. The two areas 4 and 5, on the other hand, differ in 

 important respects from 6 and 7. Of the 71 genera 121 species there 

 are 4 genera 28 species absent from 3 ; 21 genera 52 species absent 

 from 6 ; 25 genera 66 species absent from 7. In 5 there are 39 

 genera 90 species absent. Genera absent in 3, Pycnoptilus, 

 Monarcha, Calamanthus ; in 6, Oriolus, Myiagra, Sphenura, 

 Psophodes, Atrichia ; in 7, Pycnoptilus, Menura ; in 5, -ZEgintha, 

 Ptilonorhynchus, Piezorhynchus, Menura. 



The genus peculiar to this area is Pycnoptilus, the species 

 Manorhina melanophrys, Ptilotis cassidix, Menura superba, Menura 

 victorise, Sericornis osculans, Pycnoptilus floccosus. 



AREA 5. The insular area of 4. Of 34 genera 55 species, it does 

 not appear to hold a genus not common with 4, unless Acanthornis 

 (of Legge, Sericornis of other authors) stands alone. The relation- 

 ship is not so strong with 6, for while 1 genus 14 species are not in 

 4, there are 4 genera 29 species not found in 6. 



The reciprocal of 6 to 5 in number of genera and species (36 genera 

 103 species) is practically the same as that of 4 to 5 (39 genera 91) 

 species). Genera absent in 6, Myiagra, Cisticola, and Stipiturus 

 (all present in 4). Peculiar to the island are 14 species. 



AREA 6. Apparently the relation is to 7, 9, and 4, in that order. 

 The total number of genera is 65, species 117. Absent in 4 are 17 genera 

 53 species; in 9, 11 genera 61 species; in 7, 5 genera 24 species. 

 Genera absent in 4, Drymacedus, Xerophila, Oreoica, Entomophila, 



(all in 4). The species peculiar to this area are Xerophila 

 pectoralis and Mirafra secunda, 



AREA 7. It has 65 genera and 126 species, and although it appears 

 to be more closely related to 6, it is closely related to 3. In this area 

 there are 5 genera 29 species absent from 6; 10 genera 49 species 

 absent in 3 ; 16 genera 46 species absent in 9 ; 19 genera 69 species 

 absent in 2 ; 21 genera 68 species absent in 4 ; 26 genera 96 species 

 absent in 1 ; 31 genera 92 species absent in 8. Area 5 is practically 4. 



In the separate areas it will be noticed that the relationship 

 between area 7 and other areas is in the following order : 8, 1, 4, 2, 

 9, 3, 6, area 8 showing the most^ marked difference, and 6 the 

 strongest affinity. The closest relationship appears to be to 6, then 



3, 9, 2, 4, 1, 8 in order. The boundary between 6 and 7 is not a strong 

 one. In 7, absent from 6, are Bathilda, Ernblema, Aidemosyne, 

 Myiagra, Gerygone ; absent from 3, Struthidea, Aruytis, Drymacedus, 

 Calamanthus, Entomophila ; absent from 9, Lalage, Smicrornis, 

 Myiagra, Sphenostoma, Entomyza; absent from 2, Pteropodocys, 

 Acanthochaera, Amytis, Calamanthus, Staganopleura ; absent from 



4, Chlamydodera, Xerophila, Oreoica, Entomophila, Emblema ; 

 absent from 1, Corcorax, Cinclosoma, Acanthiza, Falcuiiculus, 

 Strepera; absent from 8, Amytis, Sericornis, Hylacola, Zosterops, 

 Megalurus. There are no known genera peculiar to 7. The follow- 

 ing species are not beyond it : Rhipidura albicauda, Amytis goyderi, 

 Calamanthus isabellinus, Xerophila nigricincta.
