 Syn. Macropus rapha, Flower 2. 



Procoptodon pusio, Owen 3 {in parte). 



This form is mainly, if not entirely, distinguished from the pre- 

 ceding species by its inferior dimensions, and since there is a con- 

 siderable amount of variation in the size of the following specimens, 

 it is not improbable that it will eventually prove merely a smaU 

 race of that species. 



Hah. Queensland and New South Wales. 



39996. The imperfect palate of a small immature individual appa- 

 (Pig.) rently belonging to this species ; from the Pleistocene of 

 Queensland. Shows the first three true molars in use,

 -Trans.' 1874, pi. Ixxvii. figs. 2-6, and ' Extinct Mammals
