Habitat : Central districts. 



As to the habits of the Jerboa-Hke species, Spencer and Gillen suggest that 

 " probably the real advantage of the jumping method of progression amongst the 

 smaller animals Hes in the difficulty that birds experience in pouncing do\\7i upo^i an 

 animal which is proceeding by leaps and bounds. It has certainty nothing to do directly 

 mth the sandy and arid nature of the country. "^^

Notomys gouldii (Gray, 1841), Gould, 1863. 



This species was first noted by Gray in the Appendix to Grey's " Travels in 

 Australia," pp. 404 & 413, but it was not described. It was then figured by Gould in 

 Mamm. Austr., iii, pi. 9, as Hapalotis mitchelli, but the correct designation of H. gouldii 

 was pointed out by Gould in his introduction. Apparently i/a^aZo^^'s richardsoni, Gray, 

 is a synonjon. In our " Zool. Voy. Erebus & Terror," vol. i, dated 1845-1875, the 

 reference on p. 12d notes a previous publication of the same work wliich suggests 

 priority to richardsoni, but Oldfield Thomas has pointed out (Brit. Mus. Cat. Marsupiaha, 

 p. 227, footnote) that the official date is 1875.
