in the Walyema Swamps area. This bears a plausible similarity 

 to the "Moort" of Shortridge, whereas the native name of gilbertii 

 was "Grul-gyte" (Gould, 1841, text to pi. 15) or "Ngil-gyte" (Gould, 

 1863, vol. 2, p. 79). 



For some years past the Broad-faced Rat-kangaroo has been 

 considered possibly or probably extinct (Shortridge, 1910, p. 825; 

 Le Souef and Burrell, 1926, p. 237; A. S. Le Souef, in litt., February 

 15, 1937; E. Le G. Troughton, in litt., April 16, 1937). Finally, L. 

 Glauert (in litt., March 17, 1937) definitely lists it as extinct.

Formerly ranging from South Australia through Victoria and 

 New South Wales to southern Queensland, the Potoroo has become 

 extinct in South Australia and possibly in New South Wales. Its 

 status in Queensland does not seem to be very definitely known, 

 but it survives in some numbers in certain districts of Victoria. 



The Potoroo is distinguished from other species of its genus by its 

 elongated head and short tarsus; the fur is long, loose, and slightly
