ISABELLIKE ELoreAEOO. 



Fur of medium length, very soft and fine, but not woolly. 

 General colour rich foxy red ; underside and limbs white. Eront 

 of neck pure white, sharply defined from the rufous colour of the 

 nape by a ridge of opposed hairs. Belly and upper part of arms 

 white. Tail rufous grey. 



Dimensions about the same as those of M. rufus. 



Hob. North-west Australia. 



Type in collection. 



The above are all the particulars that can be obtained about this 

 species from the only known specimen, which consists merely of a 

 fiat skin, without head, arms below elbows, legs or tip of tail, so 

 that it is almost impossible to make out its afiinities. It appears, 

 however, to be most nearly allied to M. rufus, from which it differs 

 by its longer straighter fur, and by the sharp separation of the 

 white on the front of the neck from the dark colour on the back. 

 The species is evidently an exceedingly fine and handsome one, and 

 it is much to be hoped that further specimens will soon be obtained 

 of it.
