Land and Fresh-water Vertebrates in Victoria. 39 



Among the Dasyurids we may note the restriction of Phasco- 

 logah caiura, Sminthopsis murina, Antechinomys lanigera and 

 Dasyurus geoffroyi to N.W. Victoria, and the restriction of 

 Phascologah minima, Thylacinus cynocephalus and Sarcophilus 

 ursinus to Tasmania ; the former apparently due to the climatic 

 (especially, as has been suggested by Professor Spencer, probably 

 the hygrometric) barrier, and the latter to the absence of the 

 dingo, while we have already alluded to the influence of the 

 absence of the dingo on the perpetuation of the larger Tasmanian 

 carnivorous marsupials in Tasmania. Further, while Phascologah 

 flavipes and the more widely distributed P. penicillata occur in 

 North and in South Victoria, P. sivainsoni and Sminthopsis 

 leucopits and Dasyurus maculatus are found in Tasmania and only 

 the moister districts of Victoria.

Perameles. 



P. ooesuta, Shaw - 

 P. nasuta, Geoff. - 

 P. gunnii, Gray - 

 P. bougainvilii, Quoy A; Gaim.

CH.EROPUS. 



C. castanotis, Gray 



Thus Perameles fasciata and Chceropus castanotis are confined to 

 the less humid part of Victoria, where P. obesula is wantingj 

 though it occurs in Tasmania and Southern Victoria.
