Procoptodon rapha, Owen l . 

 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 small 

 race of that species. 



Hob. Queensland and New South Wales. 



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

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

 Queensland. Shows the first three true molars in use, 

 with pm. 4 in alveolo. Figured by Owen in the ' Phil. 

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

 of Australia,' pi. xc. figs. 26, as P.pusio, of which it is the 

 type ; it cannot, however, be specifically distinguished from 

 No. M. 1519. Presented by Sir D. Cooper, Bart., 1866. 



46836. The nearly entire mandible, showing the left incisor, and 

 (Fig.) the entire series of cheek-teeth on both sides; from the 

 Pleistocene of Queensland. Figured by Owen in the 

 ' Extinct Mammals of Australia,' pi. cxxviii. The length 

 of the series of cheek-teeth is 0,092, and that of the four 

 true molars 0,078. 



Presented by Dr. George Benmtt, 1875. 



48420. The symphysis and nearly entire left ramus of the mandible, 

 showing the five cheek-teeth, and the alveolus of the 

 incisor ; from Queensland. 



Presented by Dr. George Bennett, 1877. 



M. 3676. Cast of the nearly entire right ramus of the mandible, sh<5w- 

 ing the five cheek-teeth (pmT4 imperfect). The original, of 

 which the exact locality is unknown, is preserved in the 

 Australian Museum, Sydney, and is figured by Owen in 

 the ' Phil. Trans.' 1874, pi. Ixxviii. figs. 1-3. 



Presented by Sir E. Owen, K.C.B.
