Of the different varieties of M. rattus described by Thomas ' and

^ Besides the specimen of M. raHits there are in the collection three specimens 

 (skins or in spirit) of two or three species of Mus from North Australia. 

 But without larger series from the different localities it is hardly possible 

 at present to work them out satisfactorily ; and as the description of isolated 

 specimens of this genus only causes further confusion, I prefer to omit them 

 altogether.
