Section VIII. — Analysis of the Papuan Mammal- 

 fauna 



The number of genera of mammals represented in the 

 Papuan Sub-region is fifty; of these eight are restricted 

 to the Sub - region (namely, Proechidna, Distmchurus, 

 Dorcopsis, Chiuromys, Pteralopex, Nesonycteris, Melonyc- 

 teris, and Anthops). There are also twelve genera, nearly 

 all marsupials, common to the Papuan Sub-region and 

 Australia ; and sixteen genera common to the Papuan 

 Sub-region and the Oriental Kegion. Of these, however, 

 only six (Sus and five genera of bats) penetrate so far 

 eastwards as New Guinea ; the other ten are stragglers 

 over " Wallace's Line " as far as the Timor group and the 

 Moluccas only. Thirteen genera (Phalanger, Mus, and 

 eleven genera of Bats) are found in both the Oriental 

 Region and in the Papuan and Austral Sub-regions.
