102 EXTINCT AND VANISHING MAMMALS 



"Mr. J. T. Tunney, whose fame as a collector is world-wide, in- 

 formed me that I could only hope to get the Crescent Wallaby . . . 

 along one obscure river [of Western Australia], and a forlorn hope 

 at that. Such a Wallaby should be energetically sought, trapped, 

 and placed, not in Zoological Gardens, but in the haven of a properly 

 supervised national reserve." (Troughton, 1923, p. 155.) 



It occurs in "South-Western Australia, in isolated localities to the 

 west of the lower Great Southern Railway, probably on the verge of 

 extinction in the settled districts, but surviving further east towards 

 'the Great Victoria Desert" (Glauert, 1933, p. 29) . 



It is "still found on the Nullarbor Plain" (A. S. Le Souef, in litt., 

 February 15, 1937). 



Jones (1924, p. 234) writes of its status as follows: 



"In 1884 Mr. E. B. Sanger reported the Crescent-marked Wallaby 

 from the Centre and in the British Museum catalogue of 1888 three 

 South Australian specimens, collected by Sir George Grey, are 

 recorded. 



"The Elder Expedition in 1891 met with it in the Everard Ranges 

 .... The Horn Expedition of 1894 obtained two specimens at 

 Alice Springs. I know of no more recent observations, and proba- 

 bly so far as South Australia is concerned the animal has ceased 

 to exist." 



C. W. Brazenor writes (in litt., March 3, 1937) of a single Vic- 

 torian record, from the River Murray in 1857. 



"Regarded as verging upon extinction in the settled areas of its 

 south Western Australian habitat, but surviving in the more desert- 

 like conditions between the Great Victoria Desert and Trans-Rail- 

 way, to the eastward. Extinction may be regarded as inevitable, 

 without establishment under favourable conditions." (E. Le G. 

 Troughton, in litt., April 16, 1937.) 



Doubtless settlement and the concomitant imported pests have 

 accounted for the decline of this lovely wallaby.

Formerly abundant in eastern Australia, this animal has suffered 

 serious reduction of range and numbers.
