We have here 
no sign of 
any 
approach to the Mammalian 
fauna of the Oriental region, for though Bus has appeared, the 
Muridse (rats and mice) seem to be wanting. 
In Birds the case is very different, since we at once meet 
with important groups, either wholly, or almost peculiar to 
the Papuan fauna. According to a careful estimate, embodying 
the recent discoveries of Meyer and D ’Albertis, there are 
350 species of Papuan land-birds comprised iu 136 genera. 
About 300 of the species are absolutely peculiar to the dis- 
trict, while 39 of the genera are exclusively Papuan or just 
extend into the Moluccas, or into North Australia where it 
closely approaches New Guinea. In analysing the genera we 
may set aside 31 as having a wide range, and being of no signifi- 
cance in distribution ; such are most of the birds of prey, with 
the genera Hirundo, Caprimulgus , Zosteraps ; and others widely 
spread in both the Oriental and Australian regions, as Dicoeum , 
Munia , Eiulynamis, &c. Of the remainder, as above stated, 
about 39 are peculiar to the Papuan fauna, 50 are characteristic 
Australian genera ; 9 are more especially Malayan, and as much 
Australian as Oriental; while 7 only, appear to be typically 
Oriental with a discontinuous distribution, none of them occurring 
in the Moluccas. 
1 See Ann. Nat. Hist., 1873, p. 418, where the species is said to inhabit 
the Aru Islands and Celebes, which renders it not improbable that it may 
have been oarried to the former islands from the latter.
