Habitat. — Streams of Northern Tasmania. 

 Extremely abundant on the banks of the river Tamar, and 

 probably widely distributed over the island. Settlers residing 

 near the river suffer much from its destructive propensities. 

 Specimens of a very much larger size than the type are occa- 

 sionally seen. 



Mus Leucopus. 

 Since the description of " leucopus " was written we have 

 received from Storey's Creek and Long's Plains, and the 

 Eoyal Society's Museum at Hobart, from the West Coast, 

 specimens of a rat, agreeing in all its essential characters

 and darker fur. We do not at present feel justified in 

 describing it as a seimrate species. The type specimen, an 

 adult male, from Kentishbury, measured

 there are not many that are likely to become of much utility, 

 yet there are a few which are deserving of notice in this 

 respect, as they are of great commercial importance in their 

 native country. 



I would first call attention to the South American Pinus
