 RODENTIA. 



Here we are at once struck with the restriction of Hapalotis to 

 the northern parts of Victoria. The moister climates of Southern 

 and Eastern Victoria and of Tasmania are unfavourable to the 

 genus. Mastacomys has been met with in Central Australia 

 (Horn Expedition) and in the fossil state in New South Wales. 

 Hydromys is widely spread over Australia. The species of Mus 

 clearly need more attention. If the Tasmanian species enume- 

 rated all hold good, it would be a very remarkable thing if a 

 large number of them should not also occur in Victoria. That 

 the Victorian mice have been so far pretty much neglected must 

 indeed be freely admitted.
